This can be used to clean up any 3rd party bindings to the DOM + * element before it is removed. + * + * ### Methods + * - `controller(name)` - retrieves the controller of the current element or its parent. By default + * retrieves controller associated with the `ngController` directive. If `name` is provided as + * camelCase directive name, then the controller for this directive will be retrieved (e.g. + * `'ngModel'`). + * - `injector()` - retrieves the injector of the current element or its parent. + * - `scope()` - retrieves the {@link ng.$rootScope.Scope scope} of the current + * element or its parent. Requires {@link guide/production#disabling-debug-data Debug Data} to + * be enabled. + * - `isolateScope()` - retrieves an isolate {@link ng.$rootScope.Scope scope} if one is attached directly to the + * current element. This getter should be used only on elements that contain a directive which starts a new isolate + * scope. Calling `scope()` on this element always returns the original non-isolate scope. + * Requires {@link guide/production#disabling-debug-data Debug Data} to be enabled. + * - `inheritedData()` - same as `data()`, but walks up the DOM until a value is found or the top + * parent element is reached. + * + * @param {string|DOMElement} element HTML string or DOMElement to be wrapped into jQuery. + * @returns {Object} jQuery object. + */ + +JQLite.expando = 'ng339'; + +var jqCache = JQLite.cache = {}, + jqId = 1, + addEventListenerFn = function(element, type, fn) { + element.addEventListener(type, fn, false); + }, + removeEventListenerFn = function(element, type, fn) { + element.removeEventListener(type, fn, false); + }; + +/* + * !!!

+ * **Note:** This document is an in-depth reference of all directive options. + * For a gentle introduction to directives with examples of common use cases, + * see the {@link guide/directive directive guide}. + *
+ * + * ## Comprehensive Directive API + * + * There are many different options for a directive. + * + * The difference resides in the return value of the factory function. + * You can either return a "Directive Definition Object" (see below) that defines the directive properties, + * or just the `postLink` function (all other properties will have the default values). + * + *
+ * **Best Practice:** It's recommended to use the "directive definition object" form. + *
+ * + * Here's an example directive declared with a Directive Definition Object: + * + * ```js + * var myModule = angular.module(...); + * + * myModule.directive('directiveName', function factory(injectables) { + * var directiveDefinitionObject = { + * priority: 0, + * template: '
', // or // function(tElement, tAttrs) { ... }, + * // or + * // templateUrl: 'directive.html', // or // function(tElement, tAttrs) { ... }, + * transclude: false, + * restrict: 'A', + * templateNamespace: 'html', + * scope: false, + * controller: function($scope, $element, $attrs, $transclude, otherInjectables) { ... }, + * controllerAs: 'stringIdentifier', + * bindToController: false, + * require: 'siblingDirectiveName', // or // ['^parentDirectiveName', '?optionalDirectiveName', '?^optionalParent'], + * compile: function compile(tElement, tAttrs, transclude) { + * return { + * pre: function preLink(scope, iElement, iAttrs, controller) { ... }, + * post: function postLink(scope, iElement, iAttrs, controller) { ... } + * } + * // or + * // return function postLink( ... ) { ... } + * }, + * // or + * // link: { + * // pre: function preLink(scope, iElement, iAttrs, controller) { ... }, + * // post: function postLink(scope, iElement, iAttrs, controller) { ... } + * // } + * // or + * // link: function postLink( ... ) { ... } + * }; + * return directiveDefinitionObject; + * }); + * ``` + * + *
+ * **Note:** Any unspecified options will use the default value. You can see the default values below. + *
+ * + * Therefore the above can be simplified as: + * + * ```js + * var myModule = angular.module(...); + * + * myModule.directive('directiveName', function factory(injectables) { + * var directiveDefinitionObject = { + * link: function postLink(scope, iElement, iAttrs) { ... } + * }; + * return directiveDefinitionObject; + * // or + * // return function postLink(scope, iElement, iAttrs) { ... } + * }); + * ``` + * + * + * + * ### Directive Definition Object + * + * The directive definition object provides instructions to the {@link ng.$compile + * compiler}. The attributes are: + * + * #### `multiElement` + * When this property is set to true, the HTML compiler will collect DOM nodes between + * nodes with the attributes `directive-name-start` and `directive-name-end`, and group them + * together as the directive elements. It is recommended that this feature be used on directives + * which are not strictly behavioural (such as {@link ngClick}), and which + * do not manipulate or replace child nodes (such as {@link ngInclude}). + * + * #### `priority` + * When there are multiple directives defined on a single DOM element, sometimes it + * is necessary to specify the order in which the directives are applied. The `priority` is used + * to sort the directives before their `compile` functions get called. Priority is defined as a + * number. Directives with greater numerical `priority` are compiled first. Pre-link functions + * are also run in priority order, but post-link functions are run in reverse order. The order + * of directives with the same priority is undefined. The default priority is `0`. + * + * #### `terminal` + * If set to true then the current `priority` will be the last set of directives + * which will execute (any directives at the current priority will still execute + * as the order of execution on same `priority` is undefined). Note that expressions + * and other directives used in the directive's template will also be excluded from execution. + * + * #### `scope` + * **If set to `true`,** then a new scope will be created for this directive. If multiple directives on the + * same element request a new scope, only one new scope is created. The new scope rule does not + * apply for the root of the template since the root of the template always gets a new scope. + * + * **If set to `{}` (object hash),** then a new "isolate" scope is created. The 'isolate' scope differs from + * normal scope in that it does not prototypically inherit from the parent scope. This is useful + * when creating reusable components, which should not accidentally read or modify data in the + * parent scope. + * + * The 'isolate' scope takes an object hash which defines a set of local scope properties + * derived from the parent scope. These local properties are useful for aliasing values for + * templates. Locals definition is a hash of local scope property to its source: + * + * * `@` or `@attr` - bind a local scope property to the value of DOM attribute. The result is + * always a string since DOM attributes are strings. If no `attr` name is specified then the + * attribute name is assumed to be the same as the local name. + * Given `` and widget definition + * of `scope: { localName:'@myAttr' }`, then widget scope property `localName` will reflect + * the interpolated value of `hello {{name}}`. As the `name` attribute changes so will the + * `localName` property on the widget scope. The `name` is read from the parent scope (not + * component scope). + * + * * `=` or `=attr` - set up bi-directional binding between a local scope property and the + * parent scope property of name defined via the value of the `attr` attribute. If no `attr` + * name is specified then the attribute name is assumed to be the same as the local name. + * Given `` and widget definition of + * `scope: { localModel:'=myAttr' }`, then widget scope property `localModel` will reflect the + * value of `parentModel` on the parent scope. Any changes to `parentModel` will be reflected + * in `localModel` and any changes in `localModel` will reflect in `parentModel`. If the parent + * scope property doesn't exist, it will throw a NON_ASSIGNABLE_MODEL_EXPRESSION exception. You + * can avoid this behavior using `=?` or `=?attr` in order to flag the property as optional. If + * you want to shallow watch for changes (i.e. $watchCollection instead of $watch) you can use + * `=*` or `=*attr` (`=*?` or `=*?attr` if the property is optional). + * + * * `&` or `&attr` - provides a way to execute an expression in the context of the parent scope. + * If no `attr` name is specified then the attribute name is assumed to be the same as the + * local name. Given `` and widget definition of + * `scope: { localFn:'&myAttr' }`, then isolate scope property `localFn` will point to + * a function wrapper for the `count = count + value` expression. Often it's desirable to + * pass data from the isolated scope via an expression to the parent scope, this can be + * done by passing a map of local variable names and values into the expression wrapper fn. + * For example, if the expression is `increment(amount)` then we can specify the amount value + * by calling the `localFn` as `localFn({amount: 22})`. + * + * + * #### `bindToController` + * When an isolate scope is used for a component (see above), and `controllerAs` is used, `bindToController: true` will + * allow a component to have its properties bound to the controller, rather than to scope. When the controller + * is instantiated, the initial values of the isolate scope bindings are already available. + * + * #### `controller` + * Controller constructor function. The controller is instantiated before the + * pre-linking phase and it is shared with other directives (see + * `require` attribute). This allows the directives to communicate with each other and augment + * each other's behavior. The controller is injectable (and supports bracket notation) with the following locals: + * + * * `$scope` - Current scope associated with the element + * * `$element` - Current element + * * `$attrs` - Current attributes object for the element + * * `$transclude` - A transclude linking function pre-bound to the correct transclusion scope: + * `function([scope], cloneLinkingFn, futureParentElement)`. + * * `scope`: optional argument to override the scope. + * * `cloneLinkingFn`: optional argument to create clones of the original transcluded content. + * * `futureParentElement`: + * * defines the parent to which the `cloneLinkingFn` will add the cloned elements. + * * default: `$element.parent()` resp. `$element` for `transclude:'element'` resp. `transclude:true`. + * * only needed for transcludes that are allowed to contain non html elements (e.g. SVG elements) + * and when the `cloneLinkinFn` is passed, + * as those elements need to created and cloned in a special way when they are defined outside their + * usual containers (e.g. like ``). + * * See also the `directive.templateNamespace` property. + * + * + * #### `require` + * Require another directive and inject its controller as the fourth argument to the linking function. The + * `require` takes a string name (or array of strings) of the directive(s) to pass in. If an array is used, the + * injected argument will be an array in corresponding order. If no such directive can be + * found, or if the directive does not have a controller, then an error is raised (unless no link function + * is specified, in which case error checking is skipped). The name can be prefixed with: + * + * * (no prefix) - Locate the required controller on the current element. Throw an error if not found. + * * `?` - Attempt to locate the required controller or pass `null` to the `link` fn if not found. + * * `^` - Locate the required controller by searching the element and its parents. Throw an error if not found. + * * `^^` - Locate the required controller by searching the element's parents. Throw an error if not found. + * * `?^` - Attempt to locate the required controller by searching the element and its parents or pass + * `null` to the `link` fn if not found. + * * `?^^` - Attempt to locate the required controller by searching the element's parents, or pass + * `null` to the `link` fn if not found. + * + * + * #### `controllerAs` + * Identifier name for a reference to the controller in the directive's scope. + * This allows the controller to be referenced from the directive template. The directive + * needs to define a scope for this configuration to be used. Useful in the case when + * directive is used as component. + * + * + * #### `restrict` + * String of subset of `EACM` which restricts the directive to a specific directive + * declaration style. If omitted, the defaults (elements and attributes) are used. + * + * * `E` - Element name (default): `` + * * `A` - Attribute (default): `
` + * * `C` - Class: `
` + * * `M` - Comment: `` + * + * + * #### `templateNamespace` + * String representing the document type used by the markup in the template. + * AngularJS needs this information as those elements need to be created and cloned + * in a special way when they are defined outside their usual containers like `` and ``. + * + * * `html` - All root nodes in the template are HTML. Root nodes may also be + * top-level elements such as `` or ``. + * * `svg` - The root nodes in the template are SVG elements (excluding ``). + * * `math` - The root nodes in the template are MathML elements (excluding ``). + * + * If no `templateNamespace` is specified, then the namespace is considered to be `html`. + * + * #### `template` + * HTML markup that may: + * * Replace the contents of the directive's element (default). + * * Replace the directive's element itself (if `replace` is true - DEPRECATED). + * * Wrap the contents of the directive's element (if `transclude` is true). + * + * Value may be: + * + * * A string. For example `
{{delete_str}}
`. + * * A function which takes two arguments `tElement` and `tAttrs` (described in the `compile` + * function api below) and returns a string value. + * + * + * #### `templateUrl` + * This is similar to `template` but the template is loaded from the specified URL, asynchronously. + * + * Because template loading is asynchronous the compiler will suspend compilation of directives on that element + * for later when the template has been resolved. In the meantime it will continue to compile and link + * sibling and parent elements as though this element had not contained any directives. + * + * The compiler does not suspend the entire compilation to wait for templates to be loaded because this + * would result in the whole app "stalling" until all templates are loaded asynchronously - even in the + * case when only one deeply nested directive has `templateUrl`. + * + * Template loading is asynchronous even if the template has been preloaded into the {@link $templateCache} + * + * You can specify `templateUrl` as a string representing the URL or as a function which takes two + * arguments `tElement` and `tAttrs` (described in the `compile` function api below) and returns + * a string value representing the url. In either case, the template URL is passed through {@link + * $sce#getTrustedResourceUrl $sce.getTrustedResourceUrl}. + * + * + * #### `replace` ([*DEPRECATED*!], will be removed in next major release - i.e. v2.0) + * specify what the template should replace. Defaults to `false`. + * + * * `true` - the template will replace the directive's element. + * * `false` - the template will replace the contents of the directive's element. + * + * The replacement process migrates all of the attributes / classes from the old element to the new + * one. See the {@link guide/directive#template-expanding-directive + * Directives Guide} for an example. + * + * There are very few scenarios where element replacement is required for the application function, + * the main one being reusable custom components that are used within SVG contexts + * (because SVG doesn't work with custom elements in the DOM tree). + * + * #### `transclude` + * Extract the contents of the element where the directive appears and make it available to the directive. + * The contents are compiled and provided to the directive as a **transclusion function**. See the + * {@link $compile#transclusion Transclusion} section below. + * + * There are two kinds of transclusion depending upon whether you want to transclude just the contents of the + * directive's element or the entire element: + * + * * `true` - transclude the content (i.e. the child nodes) of the directive's element. + * * `'element'` - transclude the whole of the directive's element including any directives on this + * element that defined at a lower priority than this directive. When used, the `template` + * property is ignored. + * + * + * #### `compile` + * + * ```js + * function compile(tElement, tAttrs, transclude) { ... } + * ``` + * + * The compile function deals with transforming the template DOM. Since most directives do not do + * template transformation, it is not used often. The compile function takes the following arguments: + * + * * `tElement` - template element - The element where the directive has been declared. It is + * safe to do template transformation on the element and child elements only. + * + * * `tAttrs` - template attributes - Normalized list of attributes declared on this element shared + * between all directive compile functions. + * + * * `transclude` - [*DEPRECATED*!] A transclude linking function: `function(scope, cloneLinkingFn)` + * + *
+ * **Note:** The template instance and the link instance may be different objects if the template has + * been cloned. For this reason it is **not** safe to do anything other than DOM transformations that + * apply to all cloned DOM nodes within the compile function. Specifically, DOM listener registration + * should be done in a linking function rather than in a compile function. + *
+ + *
+ * **Note:** The compile function cannot handle directives that recursively use themselves in their + * own templates or compile functions. Compiling these directives results in an infinite loop and a + * stack overflow errors. + * + * This can be avoided by manually using $compile in the postLink function to imperatively compile + * a directive's template instead of relying on automatic template compilation via `template` or + * `templateUrl` declaration or manual compilation inside the compile function. + *
+ * + *
+ * **Note:** The `transclude` function that is passed to the compile function is deprecated, as it + * e.g. does not know about the right outer scope. Please use the transclude function that is passed + * to the link function instead. + *
+ + * A compile function can have a return value which can be either a function or an object. + * + * * returning a (post-link) function - is equivalent to registering the linking function via the + * `link` property of the config object when the compile function is empty. + * + * * returning an object with function(s) registered via `pre` and `post` properties - allows you to + * control when a linking function should be called during the linking phase. See info about + * pre-linking and post-linking functions below. + * + * + * #### `link` + * This property is used only if the `compile` property is not defined. + * + * ```js + * function link(scope, iElement, iAttrs, controller, transcludeFn) { ... } + * ``` + * + * The link function is responsible for registering DOM listeners as well as updating the DOM. It is + * executed after the template has been cloned. This is where most of the directive logic will be + * put. + * + * * `scope` - {@link ng.$rootScope.Scope Scope} - The scope to be used by the + * directive for registering {@link ng.$rootScope.Scope#$watch watches}. + * + * * `iElement` - instance element - The element where the directive is to be used. It is safe to + * manipulate the children of the element only in `postLink` function since the children have + * already been linked. + * + * * `iAttrs` - instance attributes - Normalized list of attributes declared on this element shared + * between all directive linking functions. + * + * * `controller` - the directive's required controller instance(s) - Instances are shared + * among all directives, which allows the directives to use the controllers as a communication + * channel. The exact value depends on the directive's `require` property: + * * no controller(s) required: the directive's own controller, or `undefined` if it doesn't have one + * * `string`: the controller instance + * * `array`: array of controller instances + * + * If a required controller cannot be found, and it is optional, the instance is `null`, + * otherwise the {@link error:$compile:ctreq Missing Required Controller} error is thrown. + * + * Note that you can also require the directive's own controller - it will be made available like + * any other controller. + * + * * `transcludeFn` - A transclude linking function pre-bound to the correct transclusion scope. + * This is the same as the `$transclude` + * parameter of directive controllers, see there for details. + * `function([scope], cloneLinkingFn, futureParentElement)`. + * + * #### Pre-linking function + * + * Executed before the child elements are linked. Not safe to do DOM transformation since the + * compiler linking function will fail to locate the correct elements for linking. + * + * #### Post-linking function + * + * Executed after the child elements are linked. + * + * Note that child elements that contain `templateUrl` directives will not have been compiled + * and linked since they are waiting for their template to load asynchronously and their own + * compilation and linking has been suspended until that occurs. + * + * It is safe to do DOM transformation in the post-linking function on elements that are not waiting + * for their async templates to be resolved. + * + * + * ### Transclusion + * + * Transclusion is the process of extracting a collection of DOM elements from one part of the DOM and + * copying them to another part of the DOM, while maintaining their connection to the original AngularJS + * scope from where they were taken. + * + * Transclusion is used (often with {@link ngTransclude}) to insert the + * original contents of a directive's element into a specified place in the template of the directive. + * The benefit of transclusion, over simply moving the DOM elements manually, is that the transcluded + * content has access to the properties on the scope from which it was taken, even if the directive + * has isolated scope. + * See the {@link guide/directive#creating-a-directive-that-wraps-other-elements Directives Guide}. + * + * This makes it possible for the widget to have private state for its template, while the transcluded + * content has access to its originating scope. + * + *
+ * **Note:** When testing an element transclude directive you must not place the directive at the root of the + * DOM fragment that is being compiled. See {@link guide/unit-testing#testing-transclusion-directives + * Testing Transclusion Directives}. + *
+ * + * #### Transclusion Functions + * + * When a directive requests transclusion, the compiler extracts its contents and provides a **transclusion + * function** to the directive's `link` function and `controller`. This transclusion function is a special + * **linking function** that will return the compiled contents linked to a new transclusion scope. + * + *
+ * If you are just using {@link ngTransclude} then you don't need to worry about this function, since + * ngTransclude will deal with it for us. + *
+ * + * If you want to manually control the insertion and removal of the transcluded content in your directive + * then you must use this transclude function. When you call a transclude function it returns a a jqLite/JQuery + * object that contains the compiled DOM, which is linked to the correct transclusion scope. + * + * When you call a transclusion function you can pass in a **clone attach function**. This function accepts + * two parameters, `function(clone, scope) { ... }`, where the `clone` is a fresh compiled copy of your transcluded + * content and the `scope` is the newly created transclusion scope, to which the clone is bound. + * + *
+ * **Best Practice**: Always provide a `cloneFn` (clone attach function) when you call a translude function + * since you then get a fresh clone of the original DOM and also have access to the new transclusion scope. + *
+ * + * It is normal practice to attach your transcluded content (`clone`) to the DOM inside your **clone + * attach function**: + * + * ```js + * var transcludedContent, transclusionScope; + * + * $transclude(function(clone, scope) { + * element.append(clone); + * transcludedContent = clone; + * transclusionScope = scope; + * }); + * ``` + * + * Later, if you want to remove the transcluded content from your DOM then you should also destroy the + * associated transclusion scope: + * + * ```js + * transcludedContent.remove(); + * transclusionScope.$destroy(); + * ``` + * + *
+ * **Best Practice**: if you intend to add and remove transcluded content manually in your directive + * (by calling the transclude function to get the DOM and calling `element.remove()` to remove it), + * then you are also responsible for calling `$destroy` on the transclusion scope. + *
+ * + * The built-in DOM manipulation directives, such as {@link ngIf}, {@link ngSwitch} and {@link ngRepeat} + * automatically destroy their transluded clones as necessary so you do not need to worry about this if + * you are simply using {@link ngTransclude} to inject the transclusion into your directive. + * + * + * #### Transclusion Scopes + * + * When you call a transclude function it returns a DOM fragment that is pre-bound to a **transclusion + * scope**. This scope is special, in that it is a child of the directive's scope (and so gets destroyed + * when the directive's scope gets destroyed) but it inherits the properties of the scope from which it + * was taken. + * + * For example consider a directive that uses transclusion and isolated scope. The DOM hierarchy might look + * like this: + * + * ```html + *
+ *
+ *
+ *
+ *
+ *
+ * ``` + * + * The `$parent` scope hierarchy will look like this: + * + * ``` + * - $rootScope + * - isolate + * - transclusion + * ``` + * + * but the scopes will inherit prototypically from different scopes to their `$parent`. + * + * ``` + * - $rootScope + * - transclusion + * - isolate + * ``` + * + * + * ### Attributes + * + * The {@link ng.$compile.directive.Attributes Attributes} object - passed as a parameter in the + * `link()` or `compile()` functions. It has a variety of uses. + * + * accessing *Normalized attribute names:* + * Directives like 'ngBind' can be expressed in many ways: 'ng:bind', `data-ng-bind`, or 'x-ng-bind'. + * the attributes object allows for normalized access to + * the attributes. + * + * * *Directive inter-communication:* All directives share the same instance of the attributes + * object which allows the directives to use the attributes object as inter directive + * communication. + * + * * *Supports interpolation:* Interpolation attributes are assigned to the attribute object + * allowing other directives to read the interpolated value. + * + * * *Observing interpolated attributes:* Use `$observe` to observe the value changes of attributes + * that contain interpolation (e.g. `src="{{bar}}"`). Not only is this very efficient but it's also + * the only way to easily get the actual value because during the linking phase the interpolation + * hasn't been evaluated yet and so the value is at this time set to `undefined`. + * + * ```js + * function linkingFn(scope, elm, attrs, ctrl) { + * // get the attribute value + * console.log(attrs.ngModel); + * + * // change the attribute + * attrs.$set('ngModel', 'new value'); + * + * // observe changes to interpolated attribute + * attrs.$observe('ngModel', function(value) { + * console.log('ngModel has changed value to ' + value); + * }); + * } + * ``` + * + * ## Example + * + *
+ * **Note**: Typically directives are registered with `module.directive`. The example below is + * to illustrate how `$compile` works. + *
+ * + + + +
+
+
+
+
+ + + it('should auto compile', function() { + var textarea = $('textarea'); + var output = $('div[compile]'); + // The initial state reads 'Hello Angular'. + expect(output.getText()).toBe('Hello Angular'); + textarea.clear(); + textarea.sendKeys('{{name}}!'); + expect(output.getText()).toBe('Angular!'); + }); + + + + * + * + * @param {string|DOMElement} element Element or HTML string to compile into a template function. + * @param {function(angular.Scope, cloneAttachFn=)} transclude function available to directives - DEPRECATED. + * + *
+ * **Note:** Passing a `transclude` function to the $compile function is deprecated, as it + * e.g. will not use the right outer scope. Please pass the transclude function as a + * `parentBoundTranscludeFn` to the link function instead. + *
+ * + * @param {number} maxPriority only apply directives lower than given priority (Only effects the + * root element(s), not their children) + * @returns {function(scope, cloneAttachFn=, options=)} a link function which is used to bind template + * (a DOM element/tree) to a scope. Where: + * + * * `scope` - A {@link ng.$rootScope.Scope Scope} to bind to. + * * `cloneAttachFn` - If `cloneAttachFn` is provided, then the link function will clone the + * `template` and call the `cloneAttachFn` function allowing the caller to attach the + * cloned elements to the DOM document at the appropriate place. The `cloneAttachFn` is + * called as:
`cloneAttachFn(clonedElement, scope)` where: + * + * * `clonedElement` - is a clone of the original `element` passed into the compiler. + * * `scope` - is the current scope with which the linking function is working with. + * + * * `options` - An optional object hash with linking options. If `options` is provided, then the following + * keys may be used to control linking behavior: + * + * * `parentBoundTranscludeFn` - the transclude function made available to + * directives; if given, it will be passed through to the link functions of + * directives found in `element` during compilation. + * * `transcludeControllers` - an object hash with keys that map controller names + * to controller instances; if given, it will make the controllers + * available to directives. + * * `futureParentElement` - defines the parent to which the `cloneAttachFn` will add + * the cloned elements; only needed for transcludes that are allowed to contain non html + * elements (e.g. SVG elements). See also the directive.controller property. + * + * Calling the linking function returns the element of the template. It is either the original + * element passed in, or the clone of the element if the `cloneAttachFn` is provided. + * + * After linking the view is not updated until after a call to $digest which typically is done by + * Angular automatically. + * + * If you need access to the bound view, there are two ways to do it: + * + * - If you are not asking the linking function to clone the template, create the DOM element(s) + * before you send them to the compiler and keep this reference around. + * ```js + * var element = $compile('

{{total}}

')(scope); + * ``` + * + * - if on the other hand, you need the element to be cloned, the view reference from the original + * example would not point to the clone, but rather to the original template that was cloned. In + * this case, you can access the clone via the cloneAttachFn: + * ```js + * var templateElement = angular.element('

{{total}}

'), + * scope = ....; + * + * var clonedElement = $compile(templateElement)(scope, function(clonedElement, scope) { + * //attach the clone to DOM document at the right place + * }); + * + * //now we have reference to the cloned DOM via `clonedElement` + * ``` + * + * + * For information on how the compiler works, see the + * {@link guide/compiler Angular HTML Compiler} section of the Developer Guide. + */ + +var $compileMinErr = minErr('$compile'); + +/** + * @ngdoc provider + * @name $compileProvider + * + * @description + */ +$CompileProvider.$inject = ['$provide', '$$sanitizeUriProvider']; +function $CompileProvider($provide, $$sanitizeUriProvider) { + var hasDirectives = {}, + Suffix = 'Directive', + COMMENT_DIRECTIVE_REGEXP = /^\s*directive\:\s*([\w\-]+)\s+(.*)$/, + CLASS_DIRECTIVE_REGEXP = /(([\w\-]+)(?:\:([^;]+))?;?)/, + ALL_OR_NOTHING_ATTRS = makeMap('ngSrc,ngSrcset,src,srcset'), + REQUIRE_PREFIX_REGEXP = /^(?:(\^\^?)?(\?)?(\^\^?)?)?/; + + // Ref: http://developers.whatwg.org/webappapis.html#event-handler-idl-attributes + // The assumption is that future DOM event attribute names will begin with + // 'on' and be composed of only English letters. + var EVENT_HANDLER_ATTR_REGEXP = /^(on[a-z]+|formaction)$/; + + function parseIsolateBindings(scope, directiveName, isController) { + var LOCAL_REGEXP = /^\s*([@&]|=(\*?))(\??)\s*(\w*)\s*$/; + + var bindings = {}; + + forEach(scope, function(definition, scopeName) { + var match = definition.match(LOCAL_REGEXP); + + if (!match) { + throw $compileMinErr('iscp', + "Invalid {3} for directive '{0}'." + + " Definition: {... {1}: '{2}' ...}", + directiveName, scopeName, definition, + (isController ?

While for simple usage patterns this doesn't matter much, for advanced usage + * it is important to familiarize yourself with these APIs and the guarantees they provide. + * + * + * ## General usage + * The `$http` service is a function which takes a single argument — a configuration object — + * that is used to generate an HTTP request and returns a {@link ng.$q promise}. + * + * ```js + * // Simple GET request example : + * $http.get('/someUrl'). + * then(function(response) { + * // this callback will be called asynchronously + * // when the response is available + * }, function(response) { + * // called asynchronously if an error occurs + * // or server returns response with an error status. + * }); + * ``` + * + * ```js + * // Simple POST request example (passing data) : + * $http.post('/someUrl', {msg:'hello word!'}). + * then(function(response) { + * // this callback will be called asynchronously + * // when the response is available + * }, function(response) { + * // called asynchronously if an error occurs + * // or server returns response with an error status. + * }); + * ``` + * + * The response object has these properties: + * + * - **data** – `{string|Object}` – The response body transformed with the transform + * functions. + * - **status** – `{number}` – HTTP status code of the response. + * - **headers** – `{function([headerName])}` – Header getter function. + * - **config** – `{Object}` – The configuration object that was used to generate the request. + * - **statusText** – `{string}` – HTTP status text of the response. + * + * A response status code between 200 and 299 is considered a success status and + * will result in the success callback being called. Note that if the response is a redirect, + * XMLHttpRequest will transparently follow it, meaning that the error callback will not be + * called for such responses. + * + * ## Writing Unit Tests that use $http + * When unit testing (using {@link ngMock ngMock}), it is necessary to call + * {@link ngMock.$httpBackend#flush $httpBackend.flush()} to flush each pending + * request using trained responses. + * + * ``` + * $httpBackend.expectGET(...); + * $http.get(...); + * $httpBackend.flush(); + * ``` + * + * ## Shortcut methods + * + * Shortcut methods are also available. All shortcut methods require passing in the URL, and + * request data must be passed in for POST/PUT requests. + * + * ```js + * $http.get('/someUrl').then(successCallback); + * $http.post('/someUrl', data).then(successCallback); + * ``` + * + * Complete list of shortcut methods: + * + * - {@link ng.$http#get $http.get} + * - {@link ng.$http#head $http.head} + * - {@link ng.$http#post $http.post} + * - {@link ng.$http#put $http.put} + * - {@link ng.$http#delete $http.delete} + * - {@link ng.$http#jsonp $http.jsonp} + * - {@link ng.$http#patch $http.patch} + * + * + * ## Deprecation Notice + *
+ * The `$http` legacy promise methods `success` and `error` have been deprecated. + * Use the standard `then` method instead. + * If {@link $httpProvider#useLegacyPromiseExtensions `$httpProvider.useLegacyPromiseExtensions`} is set to + * `false` then these methods will throw {@link $http:legacy `$http/legacy`} error. + *
+ * + * ## Setting HTTP Headers + * + * The $http service will automatically add certain HTTP headers to all requests. These defaults + * can be fully configured by accessing the `$httpProvider.defaults.headers` configuration + * object, which currently contains this default configuration: + * + * - `$httpProvider.defaults.headers.common` (headers that are common for all requests): + * - `Accept: application/json, text/plain, * / *` + * - `$httpProvider.defaults.headers.post`: (header defaults for POST requests) + * - `Content-Type: application/json` + * - `$httpProvider.defaults.headers.put` (header defaults for PUT requests) + * - `Content-Type: application/json` + * + * To add or overwrite these defaults, simply add or remove a property from these configuration + * objects. To add headers for an HTTP method other than POST or PUT, simply add a new object + * with the lowercased HTTP method name as the key, e.g. + * `$httpProvider.defaults.headers.get = { 'My-Header' : 'value' }`. + * + * The defaults can also be set at runtime via the `$http.defaults` object in the same + * fashion. For example: + * + * ``` + * module.run(function($http) { + * $http.defaults.headers.common.Authorization = 'Basic YmVlcDpib29w' + * }); + * ``` + * + * In addition, you can supply a `headers` property in the config object passed when + * calling `$http(config)`, which overrides the defaults without changing them globally. + * + * To explicitly remove a header automatically added via $httpProvider.defaults.headers on a per request basis, + * Use the `headers` property, setting the desired header to `undefined`. For example: + * + * ```js + * var req = { + * method: 'POST', + * url: 'http://example.com', + * headers: { + * 'Content-Type': undefined + * }, + * data: { test: 'test' } + * } + * + * $http(req).then(function(){...}, function(){...}); + * ``` + * + * ## Transforming Requests and Responses + * + * Both requests and responses can be transformed using transformation functions: `transformRequest` + * and `transformResponse`. These properties can be a single function that returns + * the transformed value (`function(data, headersGetter, status)`) or an array of such transformation functions, + * which allows you to `push` or `unshift` a new transformation function into the transformation chain. + * + * ### Default Transformations + * + * The `$httpProvider` provider and `$http` service expose `defaults.transformRequest` and + * `defaults.transformResponse` properties. If a request does not provide its own transformations + * then these will be applied. + * + * You can augment or replace the default transformations by modifying these properties by adding to or + * replacing the array. + * + * Angular provides the following default transformations: + * + * Request transformations (`$httpProvider.defaults.transformRequest` and `$http.defaults.transformRequest`): + * + * - If the `data` property of the request configuration object contains an object, serialize it + * into JSON format. + * + * Response transformations (`$httpProvider.defaults.transformResponse` and `$http.defaults.transformResponse`): + * + * - If XSRF prefix is detected, strip it (see Security Considerations section below). + * - If JSON response is detected, deserialize it using a JSON parser. + * + * + * ### Overriding the Default Transformations Per Request + * + * If you wish override the request/response transformations only for a single request then provide + * `transformRequest` and/or `transformResponse` properties on the configuration object passed + * into `$http`. + * + * Note that if you provide these properties on the config object the default transformations will be + * overwritten. If you wish to augment the default transformations then you must include them in your + * local transformation array. + * + * The following code demonstrates adding a new response transformation to be run after the default response + * transformations have been run. + * + * ```js + * function appendTransform(defaults, transform) { + * + * // We can't guarantee that the default transformation is an array + * defaults = angular.isArray(defaults) ? defaults : [defaults]; + * + * // Append the new transformation to the defaults + * return defaults.concat(transform); + * } + * + * $http({ + * url: '...', + * method: 'GET', + * transformResponse: appendTransform($http.defaults.transformResponse, function(value) { + * return doTransform(value); + * }) + * }); + * ``` + * + * + * ## Caching + * + * To enable caching, set the request configuration `cache` property to `true` (to use default + * cache) or to a custom cache object (built with {@link ng.$cacheFactory `$cacheFactory`}). + * When the cache is enabled, `$http` stores the response from the server in the specified + * cache. The next time the same request is made, the response is served from the cache without + * sending a request to the server. + * + * Note that even if the response is served from cache, delivery of the data is asynchronous in + * the same way that real requests are. + * + * If there are multiple GET requests for the same URL that should be cached using the same + * cache, but the cache is not populated yet, only one request to the server will be made and + * the remaining requests will be fulfilled using the response from the first request. + * + * You can change the default cache to a new object (built with + * {@link ng.$cacheFactory `$cacheFactory`}) by updating the + * {@link ng.$http#defaults `$http.defaults.cache`} property. All requests who set + * their `cache` property to `true` will now use this cache object. + * + * If you set the default cache to `false` then only requests that specify their own custom + * cache object will be cached. + * + * ## Interceptors + * + * Before you start creating interceptors, be sure to understand the + * {@link ng.$q $q and deferred/promise APIs}. + * + * For purposes of global error handling, authentication, or any kind of synchronous or + * asynchronous pre-processing of request or postprocessing of responses, it is desirable to be + * able to intercept requests before they are handed to the server and + * responses before they are handed over to the application code that + * initiated these requests. The interceptors leverage the {@link ng.$q + * promise APIs} to fulfill this need for both synchronous and asynchronous pre-processing. + * + * The interceptors are service factories that are registered with the `$httpProvider` by + * adding them to the `$httpProvider.interceptors` array. The factory is called and + * injected with dependencies (if specified) and returns the interceptor. + * + * There are two kinds of interceptors (and two kinds of rejection interceptors): + * + * * `request`: interceptors get called with a http `config` object. The function is free to + * modify the `config` object or create a new one. The function needs to return the `config` + * object directly, or a promise containing the `config` or a new `config` object. + * * `requestError`: interceptor gets called when a previous interceptor threw an error or + * resolved with a rejection. + * * `response`: interceptors get called with http `response` object. The function is free to + * modify the `response` object or create a new one. The function needs to return the `response` + * object directly, or as a promise containing the `response` or a new `response` object. + * * `responseError`: interceptor gets called when a previous interceptor threw an error or + * resolved with a rejection. + * + * + * ```js + * // register the interceptor as a service + * $provide.factory('myHttpInterceptor', function($q, dependency1, dependency2) { + * return { + * // optional method + * 'request': function(config) { + * // do something on success + * return config; + * }, + * + * // optional method + * 'requestError': function(rejection) { + * // do something on error + * if (canRecover(rejection)) { + * return responseOrNewPromise + * } + * return $q.reject(rejection); + * }, + * + * + * + * // optional method + * 'response': function(response) { + * // do something on success + * return response; + * }, + * + * // optional method + * 'responseError': function(rejection) { + * // do something on error + * if (canRecover(rejection)) { + * return responseOrNewPromise + * } + * return $q.reject(rejection); + * } + * }; + * }); + * + * $httpProvider.interceptors.push('myHttpInterceptor'); + * + * + * // alternatively, register the interceptor via an anonymous factory + * $httpProvider.interceptors.push(function($q, dependency1, dependency2) { + * return { + * 'request': function(config) { + * // same as above + * }, + * + * 'response': function(response) { + * // same as above + * } + * }; + * }); + * ``` + * + * ## Security Considerations + * + * When designing web applications, consider security threats from: + * + * - [JSON vulnerability](http://haacked.com/archive/2008/11/20/anatomy-of-a-subtle-json-vulnerability.aspx) + * - [XSRF](http://en.wikipedia.org/wiki/Cross-site_request_forgery) + * + * Both server and the client must cooperate in order to eliminate these threats. Angular comes + * pre-configured with strategies that address these issues, but for this to work backend server + * cooperation is required. + * + * ### JSON Vulnerability Protection + * + * A [JSON vulnerability](http://haacked.com/archive/2008/11/20/anatomy-of-a-subtle-json-vulnerability.aspx) + * allows third party website to turn your JSON resource URL into + * [JSONP](http://en.wikipedia.org/wiki/JSONP) request under some conditions. To + * counter this your server can prefix all JSON requests with following string `")]}',\n"`. + * Angular will automatically strip the prefix before processing it as JSON. + * + * For example if your server needs to return: + * ```js + * ['one','two'] + * ``` + * + * which is vulnerable to attack, your server can return: + * ```js + * )]}', + * ['one','two'] + * ``` + * + * Angular will strip the prefix, before processing the JSON. + * + * + * ### Cross Site Request Forgery (XSRF) Protection + * + * [XSRF](http://en.wikipedia.org/wiki/Cross-site_request_forgery) is a technique by which + * an unauthorized site can gain your user's private data. Angular provides a mechanism + * to counter XSRF. When performing XHR requests, the $http service reads a token from a cookie + * (by default, `XSRF-TOKEN`) and sets it as an HTTP header (`X-XSRF-TOKEN`). Since only + * JavaScript that runs on your domain could read the cookie, your server can be assured that + * the XHR came from JavaScript running on your domain. The header will not be set for + * cross-domain requests. + * + * To take advantage of this, your server needs to set a token in a JavaScript readable session + * cookie called `XSRF-TOKEN` on the first HTTP GET request. On subsequent XHR requests the + * server can verify that the cookie matches `X-XSRF-TOKEN` HTTP header, and therefore be sure + * that only JavaScript running on your domain could have sent the request. The token must be + * unique for each user and must be verifiable by the server (to prevent the JavaScript from + * making up its own tokens). We recommend that the token is a digest of your site's + * authentication cookie with a [salt](https://en.wikipedia.org/wiki/Salt_(cryptography)) + * for added security. + * + * The name of the headers can be specified using the xsrfHeaderName and xsrfCookieName + * properties of either $httpProvider.defaults at config-time, $http.defaults at run-time, + * or the per-request config object. + * + * In order to prevent collisions in environments where multiple Angular apps share the + * same domain or subdomain, we recommend that each application uses unique cookie name. + * + * @param {object} config Object describing the request to be made and how it should be + * processed. The object has following properties: + * + * - **method** – `{string}` – HTTP method (e.g. 'GET', 'POST', etc) + * - **url** – `{string}` – Absolute or relative URL of the resource that is being requested. + * - **params** – `{Object.}` – Map of strings or objects which will be serialized + * with the `paramSerializer` and appended as GET parameters. + * - **data** – `{string|Object}` – Data to be sent as the request message data. + * - **headers** – `{Object}` – Map of strings or functions which return strings representing + * HTTP headers to send to the server. If the return value of a function is null, the + * header will not be sent. Functions accept a config object as an argument. + * - **xsrfHeaderName** – `{string}` – Name of HTTP header to populate with the XSRF token. + * - **xsrfCookieName** – `{string}` – Name of cookie containing the XSRF token. + * - **transformRequest** – + * `{function(data, headersGetter)|Array.}` – + * transform function or an array of such functions. The transform function takes the http + * request body and headers and returns its transformed (typically serialized) version. + * See {@link ng.$http#overriding-the-default-transformations-per-request + * Overriding the Default Transformations} + * - **transformResponse** – + * `{function(data, headersGetter, status)|Array.}` – + * transform function or an array of such functions. The transform function takes the http + * response body, headers and status and returns its transformed (typically deserialized) version. + * See {@link ng.$http#overriding-the-default-transformations-per-request + * Overriding the Default TransformationjqLiks} + * - **paramSerializer** - `{string|function(Object):string}` - A function used to + * prepare the string representation of request parameters (specified as an object). + * If specified as string, it is interpreted as function registered with the + * {@link $injector $injector}, which means you can create your own serializer + * by registering it as a {@link auto.$provide#service service}. + * The default serializer is the {@link $httpParamSerializer $httpParamSerializer}; + * alternatively, you can use the {@link $httpParamSerializerJQLike $httpParamSerializerJQLike} + * - **cache** – `{boolean|Cache}` – If true, a default $http cache will be used to cache the + * GET request, otherwise if a cache instance built with + * {@link ng.$cacheFactory $cacheFactory}, this cache will be used for + * caching. + * - **timeout** – `{number|Promise}` – timeout in milliseconds, or {@link ng.$q promise} + * that should abort the request when resolved. + * - **withCredentials** - `{boolean}` - whether to set the `withCredentials` flag on the + * XHR object. See [requests with credentials](https://developer.mozilla.org/docs/Web/HTTP/Access_control_CORS#Requests_with_credentials) + * for more information. + * - **responseType** - `{string}` - see + * [XMLHttpRequest.responseType](https://developer.mozilla.org/en-US/docs/Web/API/XMLHttpRequest#xmlhttprequest-responsetype). + * + * @returns {HttpPromise} Returns a {@link ng.$q `Promise}` that will be resolved to a response object + * when the request succeeds or fails. + * + * + * @property {Array.} pendingRequests Array of config objects for currently pending + * requests. This is primarily meant to be used for debugging purposes. + * + * + * @example + + +

So, for HTML elements interpolated + * by {@link ng.$compile $compile}, or otherwise interpolated with the `mustHaveExpression` parameter + * set to `true`, the interpolated text must contain an unescaped interpolation expression. As such, + * this is typically useful only when user-data is used in rendering a template from the server, or + * when otherwise untrusted data is used by a directive. + * + * + * + *

This is similar to the native Promise implementation from ES6 Harmony, + * see [MDN](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Promise). + * + * While the constructor-style use is supported, not all of the supporting methods from ES6 Harmony promises are + * available yet. + * + * It can be used like so: + * + * ```js + * // for the purpose of this example let's assume that variables `$q` and `okToGreet` + * // are available in the current lexical scope (they could have been injected or passed in). + * + * function asyncGreet(name) { + * // perform some asynchronous operation, resolve or reject the promise when appropriate. + * return $q(function(resolve, reject) { + * setTimeout(function() { + * if (okToGreet(name)) { + * resolve('Hello, ' + name + '!'); + * } else { + * reject('Greeting ' + name + ' is not allowed.'); + * } + * }, 1000); + * }); + * } + * + * var promise = asyncGreet('Robin Hood'); + * promise.then(function(greeting) { + * alert('Success: ' + greeting); + * }, function(reason) { + * alert('Failed: ' + reason); + * }); + * ``` + * + * Note: progress/notify callbacks are not currently supported via the ES6-style interface. + * + * However, the more traditional CommonJS-style usage is still available, and documented below. + * + * [The CommonJS Promise proposal](http://wiki.commonjs.org/wiki/Promises) describes a promise as an + * interface for interacting with an object that represents the result of an action that is + * performed asynchronously, and may or may not be finished at any given point in time. + * + * From the perspective of dealing with error handling, deferred and promise APIs are to + * asynchronous programming what `try`, `catch` and `throw` keywords are to synchronous programming. + * + * ```js + * // for the purpose of this example let's assume that variables `$q` and `okToGreet` + * // are available in the current lexical scope (they could have been injected or passed in). + * + * function asyncGreet(name) { + * var deferred = $q.defer(); + * + * setTimeout(function() { + * deferred.notify('About to greet ' + name + '.'); + * + * if (okToGreet(name)) { + * deferred.resolve('Hello, ' + name + '!'); + * } else { + * deferred.reject('Greeting ' + name + ' is not allowed.'); + * } + * }, 1000); + * + * return deferred.promise; + * } + * + * var promise = asyncGreet('Robin Hood'); + * promise.then(function(greeting) { + * alert('Success: ' + greeting); + * }, function(reason) { + * alert('Failed: ' + reason); + * }, function(update) { + * alert('Got notification: ' + update); + * }); + * ``` + * + * At first it might not be obvious why this extra complexity is worth the trouble. The payoff + * comes in the way of guarantees that promise and deferred APIs make, see + * https://github.com/kriskowal/uncommonjs/blob/master/promises/specification.md. + * + * Additionally the promise api allows for composition that is very hard to do with the + * traditional callback ([CPS](http://en.wikipedia.org/wiki/Continuation-passing_style)) approach. + * For more on this please see the [Q documentation](https://github.com/kriskowal/q) especially the + * section on serial or parallel joining of promises. + * + * # The Deferred API + * + * A new instance of deferred is constructed by calling `$q.defer()`. + * + * The purpose of the deferred object is to expose the associated Promise instance as well as APIs + * that can be used for signaling the successful or unsuccessful completion, as well as the status + * of the task. + * + * **Methods** + * + * - `resolve(value)` – resolves the derived promise with the `value`. If the value is a rejection + * constructed via `$q.reject`, the promise will be rejected instead. + * - `reject(reason)` – rejects the derived promise with the `reason`. This is equivalent to + * resolving it with a rejection constructed via `$q.reject`. + * - `notify(value)` - provides updates on the status of the promise's execution. This may be called + * multiple times before the promise is either resolved or rejected. + * + * **Properties** + * + * - promise – `{Promise}` – promise object associated with this deferred. + * + * + * # The Promise API + * + * A new promise instance is created when a deferred instance is created and can be retrieved by + * calling `deferred.promise`. + * + * The purpose of the promise object is to allow for interested parties to get access to the result + * of the deferred task when it completes. + * + * **Methods** + * + * - `then(successCallback, errorCallback, notifyCallback)` – regardless of when the promise was or + * will be resolved or rejected, `then` calls one of the success or error callbacks asynchronously + * as soon as the result is available. The callbacks are called with a single argument: the result + * or rejection reason. Additionally, the notify callback may be called zero or more times to + * provide a progress indication, before the promise is resolved or rejected. + * + * This method *returns a new promise* which is resolved or rejected via the return value of the + * `successCallback`, `errorCallback` (unless that value is a promise, in which case it is resolved + * with the value which is resolved in that promise using + * [promise chaining](http://www.html5rocks.com/en/tutorials/es6/promises/#toc-promises-queues)). + * It also notifies via the return value of the `notifyCallback` method. The promise cannot be + * resolved or rejected from the notifyCallback method. + * + * - `catch(errorCallback)` – shorthand for `promise.then(null, errorCallback)` + * + * - `finally(callback, notifyCallback)` – allows you to observe either the fulfillment or rejection of a promise, + * but to do so without modifying the final value. This is useful to release resources or do some + * clean-up that needs to be done whether the promise was rejected or resolved. See the [full + * specification](https://github.com/kriskowal/q/wiki/API-Reference#promisefinallycallback) for + * more information. + * + * # Chaining promises + * + * Because calling the `then` method of a promise returns a new derived promise, it is easily + * possible to create a chain of promises: + * + * ```js + * promiseB = promiseA.then(function(result) { + * return result + 1; + * }); + * + * // promiseB will be resolved immediately after promiseA is resolved and its value + * // will be the result of promiseA incremented by 1 + * ``` + * + * It is possible to create chains of any length and since a promise can be resolved with another + * promise (which will defer its resolution further), it is possible to pause/defer resolution of + * the promises at any point in the chain. This makes it possible to implement powerful APIs like + * $http's response interceptors. + * + * + * # Differences between Kris Kowal's Q and $q + * + * There are two main differences: + * + * - $q is integrated with the {@link ng.$rootScope.Scope} Scope model observation + * mechanism in angular, which means faster propagation of resolution or rejection into your + * models and avoiding unnecessary browser repaints, which would result in flickering UI. + * - Q has many more features than $q, but that comes at a cost of bytes. $q is tiny, but contains + * all the important functionality needed for common async tasks. + * + * # Testing + * + * ```js + * it('should simulate promise', inject(function($q, $rootScope) { + * var deferred = $q.defer(); + * var promise = deferred.promise; + * var resolvedValue; + * + * promise.then(function(value) { resolvedValue = value; }); + * expect(resolvedValue).toBeUndefined(); + * + * // Simulate resolving of promise + * deferred.resolve(123); + * // Note that the 'then' function does not get called synchronously. + * // This is because we want the promise API to always be async, whether or not + * // it got called synchronously or asynchronously. + * expect(resolvedValue).toBeUndefined(); + * + * // Propagate promise resolution to 'then' functions using $apply(). + * $rootScope.$apply(); + * expect(resolvedValue).toEqual(123); + * })); + * ``` + * + * @param {function(function, function)} resolver Function which is responsible for resolving or + * rejecting the newly created promise.

One example of + * such a context is binding arbitrary html controlled by the user via `ng-bind-html`. We refer + * to these contexts as privileged or SCE contexts. + * + * As of version 1.2, Angular ships with SCE enabled by default. + * + * Note: When enabled (the default), IE<11 in quirks mode is not supported. In this mode, IE<11 allow + * one to execute arbitrary javascript by the use of the expression() syntax. Refer + * to learn more about them. + * You can ensure your document is in standards mode and not quirks mode by adding `` + * to the top of your HTML document. + * + * SCE assists in writing code in way that (a) is secure by default and (b) makes auditing for + * security vulnerabilities such as XSS, clickjacking, etc. a lot easier. + * + * Here's an example of a binding in a privileged context: + * + * ``` + * + *
+ * ``` + * + * Notice that `ng-bind-html` is bound to `userHtml` controlled by the user. With SCE + * disabled, this application allows the user to render arbitrary HTML into the DIV. + * In a more realistic example, one may be rendering user comments, blog articles, etc. via + * bindings. (HTML is just one example of a context where rendering user controlled input creates + * security vulnerabilities.) + * + * For the case of HTML, you might use a library, either on the client side, or on the server side, + * to sanitize unsafe HTML before binding to the value and rendering it in the document. + * + * How would you ensure that every place that used these types of bindings was bound to a value that + * was sanitized by your library (or returned as safe for rendering by your server?) How can you + * ensure that you didn't accidentally delete the line that sanitized the value, or renamed some + * properties/fields and forgot to update the binding to the sanitized value? + * + * To be secure by default, you want to ensure that any such bindings are disallowed unless you can + * determine that something explicitly says it's safe to use a value for binding in that + * context. You can then audit your code (a simple grep would do) to ensure that this is only done + * for those values that you can easily tell are safe - because they were received from your server, + * sanitized by your library, etc. You can organize your codebase to help with this - perhaps + * allowing only the files in a specific directory to do this. Ensuring that the internal API + * exposed by that code doesn't markup arbitrary values as safe then becomes a more manageable task. + * + * In the case of AngularJS' SCE service, one uses {@link ng.$sce#trustAs $sce.trustAs} + * (and shorthand methods such as {@link ng.$sce#trustAsHtml $sce.trustAsHtml}, etc.) to + * obtain values that will be accepted by SCE / privileged contexts. + * + * + * ## How does it work? + * + * In privileged contexts, directives and code will bind to the result of {@link ng.$sce#getTrusted + * $sce.getTrusted(context, value)} rather than to the value directly. Directives use {@link + * ng.$sce#parseAs $sce.parseAs} rather than `$parse` to watch attribute bindings, which performs the + * {@link ng.$sce#getTrusted $sce.getTrusted} behind the scenes on non-constant literals. + * + * As an example, {@link ng.directive:ngBindHtml ngBindHtml} uses {@link + * ng.$sce#parseAsHtml $sce.parseAsHtml(binding expression)}. Here's the actual code (slightly + * simplified): + * + * ``` + * var ngBindHtmlDirective = ['$sce', function($sce) { + * return function(scope, element, attr) { + * scope.$watch($sce.parseAsHtml(attr.ngBindHtml), function(value) { + * element.html(value || ''); + * }); + * }; + * }]; + * ``` + * + * ## Impact on loading templates + * + * This applies both to the {@link ng.directive:ngInclude `ng-include`} directive as well as + * `templateUrl`'s specified by {@link guide/directive directives}. + * + * By default, Angular only loads templates from the same domain and protocol as the application + * document. This is done by calling {@link ng.$sce#getTrustedResourceUrl + * $sce.getTrustedResourceUrl} on the template URL. To load templates from other domains and/or + * protocols, you may either either {@link ng.$sceDelegateProvider#resourceUrlWhitelist whitelist + * them} or {@link ng.$sce#trustAsResourceUrl wrap it} into a trusted value. + * + * *Please note*: + * The browser's + * [Same Origin Policy](https://code.google.com/p/browsersec/wiki/Part2#Same-origin_policy_for_XMLHttpRequest) + * and [Cross-Origin Resource Sharing (CORS)](http://www.w3.org/TR/cors/) + * policy apply in addition to this and may further restrict whether the template is successfully + * loaded. This means that without the right CORS policy, loading templates from a different domain + * won't work on all browsers. Also, loading templates from `file://` URL does not work on some + * browsers. + * + * ## This feels like too much overhead + * + * It's important to remember that SCE only applies to interpolation expressions. + * + * If your expressions are constant literals, they're automatically trusted and you don't need to + * call `$sce.trustAs` on them (remember to include the `ngSanitize` module) (e.g. + * `
`) just works. + * + * Additionally, `a[href]` and `img[src]` automatically sanitize their URLs and do not pass them + * through {@link ng.$sce#getTrusted $sce.getTrusted}. SCE doesn't play a role here. + * + * The included {@link ng.$sceDelegate $sceDelegate} comes with sane defaults to allow you to load + * templates in `ng-include` from your application's domain without having to even know about SCE. + * It blocks loading templates from other domains or loading templates over http from an https + * served document. You can change these by setting your own custom {@link + * ng.$sceDelegateProvider#resourceUrlWhitelist whitelists} and {@link + * ng.$sceDelegateProvider#resourceUrlBlacklist blacklists} for matching such URLs. + * + * This significantly reduces the overhead. It is far easier to pay the small overhead and have an + * application that's secure and can be audited to verify that with much more ease than bolting + * security onto an application later. + * + * + * ## What trusted context types are supported? + * + * | Context | Notes | + * |---------------------|----------------| + * | `$sce.HTML` | For HTML that's safe to source into the application. The {@link ng.directive:ngBindHtml ngBindHtml} directive uses this context for bindings. If an unsafe value is encountered and the {@link ngSanitize $sanitize} module is present this will sanitize the value instead of throwing an error. | + * | `$sce.CSS` | For CSS that's safe to source into the application. Currently unused. Feel free to use it in your own directives. | + * | `$sce.URL` | For URLs that are safe to follow as links. Currently unused (`
Note that `$sce.RESOURCE_URL` makes a stronger statement about the URL than `$sce.URL` does and therefore contexts requiring values trusted for `$sce.RESOURCE_URL` can be used anywhere that values trusted for `$sce.URL` are required. | + * | `$sce.JS` | For JavaScript that is safe to execute in your application's context. Currently unused. Feel free to use it in your own directives. | + * + * ## Format of items in {@link ng.$sceDelegateProvider#resourceUrlWhitelist resourceUrlWhitelist}/{@link ng.$sceDelegateProvider#resourceUrlBlacklist Blacklist} + * + * Each element in these arrays must be one of the following: + * + * - **'self'** + * - The special **string**, `'self'`, can be used to match against all URLs of the **same + * domain** as the application document using the **same protocol**. + * - **String** (except the special value `'self'`) + * - The string is matched against the full *normalized / absolute URL* of the resource + * being tested (substring matches are not good enough.) + * - There are exactly **two wildcard sequences** - `*` and `**`. All other characters + * match themselves. + * - `*`: matches zero or more occurrences of any character other than one of the following 6 + * characters: '`:`', '`/`', '`.`', '`?`', '`&`' and '`;`'. It's a useful wildcard for use + * in a whitelist. + * - `**`: matches zero or more occurrences of *any* character. As such, it's not + * appropriate for use in a scheme, domain, etc. as it would match too much. (e.g. + * http://**.example.com/ would match http://evil.com/?ignore=.example.com/ and that might + * not have been the intention.) Its usage at the very end of the path is ok. (e.g. + * http://foo.example.com/templates/**). + * - **RegExp** (*see caveat below*) + * - *Caveat*: While regular expressions are powerful and offer great flexibility, their syntax + * (and all the inevitable escaping) makes them *harder to maintain*. It's easy to + * accidentally introduce a bug when one updates a complex expression (imho, all regexes should + * have good test coverage). For instance, the use of `.` in the regex is correct only in a + * small number of cases. A `.` character in the regex used when matching the scheme or a + * subdomain could be matched against a `:` or literal `.` that was likely not intended. It + * is highly recommended to use the string patterns and only fall back to regular expressions + * as a last resort. + * - The regular expression must be an instance of RegExp (i.e. not a string.) It is + * matched against the **entire** *normalized / absolute URL* of the resource being tested + * (even when the RegExp did not have the `^` and `$` codes.) In addition, any flags + * present on the RegExp (such as multiline, global, ignoreCase) are ignored. + * - If you are generating your JavaScript from some other templating engine (not + * recommended, e.g. in issue [#4006](https://github.com/angular/angular.js/issues/4006)), + * remember to escape your regular expression (and be aware that you might need more than + * one level of escaping depending on your templating engine and the way you interpolated + * the value.) Do make use of your platform's escaping mechanism as it might be good + * enough before coding your own. E.g. Ruby has + * [Regexp.escape(str)](http://www.ruby-doc.org/core-2.0.0/Regexp.html#method-c-escape) + * and Python has [re.escape](http://docs.python.org/library/re.html#re.escape). + * Javascript lacks a similar built in function for escaping. Take a look at Google + * Closure library's [goog.string.regExpEscape(s)]( + * http://docs.closure-library.googlecode.com/git/closure_goog_string_string.js.source.html#line962). + * + * Refer {@link ng.$sceDelegateProvider $sceDelegateProvider} for an example. + * + * ## Show me an example using SCE. + * + * + * + *

The predicate can be negated by prefixing + * the string with `!`. + * For example `{name: "!M"}` predicate will return an array of items which have property `name` + * not containing "M". + * + * Note that a named property will match properties on the same level only, while the special + * `$` property will match properties on the same level or deeper. E.g. an array item like + * `{name: {first: 'John', last: 'Doe'}}` will **not** be matched by `{name: 'John'}`, but + * **will** be matched by `{$: 'John'}`. + * + * - `function(value, index, array)`: A predicate function can be used to write arbitrary filters. + * The function is called for each element of the array, with the element, its index, and + * the entire array itself as arguments. + * + * The final result is an array of those elements that the predicate returned true for. + * + * @param {function(actual, expected)|true|undefined} comparator Comparator which is used in + * determining if the expected value (from the filter expression) and actual value (from + * the object in the array) should be considered a match. + * + * Can be one of: + * + * - `function(actual, expected)`: + * The function will be given the object value and the predicate value to compare and + * should return true if both values should be considered equal. + * + * - `true`: A shorthand for `function(actual, expected) { return angular.equals(actual, expected)}`. + * This is essentially strict comparison of expected and actual. + * + * - `false|undefined`: A short hand for a function which will look for a substring match in case + * insensitive way. + * + * Primitive values are converted to strings. Objects are not compared against primitives, + * unless they have a custom `toString` method (e.g. `Date` objects). + * + * @example + + +

Note: if you notice numbers are not being sorted + * as expected, make sure they are actually being saved as numbers and not strings. + * + * @param {Array} array The array to sort. + * @param {function(*)|string|Array.<(function(*)|string)>=} expression A predicate to be + * used by the comparator to determine the order of elements. + * + * Can be one of: + * + * - `function`: Getter function. The result of this function will be sorted using the + * `<`, `===`, `>` operator. + * - `string`: An Angular expression. The result of this expression is used to compare elements + * (for example `name` to sort by a property called `name` or `name.substr(0, 3)` to sort by + * 3 first characters of a property called `name`). The result of a constant expression + * is interpreted as a property name to be used in comparisons (for example `"special name"` + * to sort object by the value of their `special name` property). An expression can be + * optionally prefixed with `+` or `-` to control ascending or descending sort order + * (for example, `+name` or `-name`). If no property is provided, (e.g. `'+'`) then the array + * element itself is used to compare where sorting. + * - `Array`: An array of function or string predicates. The first predicate in the array + * is used for sorting, but when two items are equivalent, the next predicate is used. + * + * If the predicate is missing or empty then it defaults to `'+'`. + * + * @param {boolean=} reverse Reverse the order of the array. + * @returns {Array} Sorted copy of the source array. + * + * + * @example + * The example below demonstrates a simple ngRepeat, where the data is sorted + * by age in descending order (predicate is set to `'-age'`). + * `reverse` is not set, which means it defaults to `false`. + + + +

This means that the outer form is valid when all of the child + * forms are valid as well. However, browsers do not allow nesting of `` elements, so + * Angular provides the {@link ng.directive:ngForm `ngForm`} directive which behaves identically to + * `` but can be nested. This allows you to have nested forms, which is very useful when + * using Angular validation directives in forms that are dynamically generated using the + * {@link ng.directive:ngRepeat `ngRepeat`} directive. Since you cannot dynamically generate the `name` + * attribute of input elements using interpolation, you have to wrap each set of repeated inputs in an + * `ngForm` directive and nest these in an outer `form` element. + * + * + * # CSS classes + * - `ng-valid` is set if the form is valid. + * - `ng-invalid` is set if the form is invalid. + * - `ng-pristine` is set if the form is pristine. + * - `ng-dirty` is set if the form is dirty. + * - `ng-submitted` is set if the form was submitted. + * + * Keep in mind that ngAnimate can detect each of these classes when added and removed. + * + * + * # Submitting a form and preventing the default action + * + * Since the role of forms in client-side Angular applications is different than in classical + * roundtrip apps, it is desirable for the browser not to translate the form submission into a full + * page reload that sends the data to the server. Instead some javascript logic should be triggered + * to handle the form submission in an application-specific way. + * + * For this reason, Angular prevents the default action (form submission to the server) unless the + * `` element has an `action` attribute specified. + * + * You can use one of the following two ways to specify what javascript method should be called when + * a form is submitted: + * + * - {@link ng.directive:ngSubmit ngSubmit} directive on the form element + * - {@link ng.directive:ngClick ngClick} directive on the first + * button or input field of type submit (input[type=submit]) + * + * To prevent double execution of the handler, use only one of the {@link ng.directive:ngSubmit ngSubmit} + * or {@link ng.directive:ngClick ngClick} directives. + * This is because of the following form submission rules in the HTML specification: + * + * - If a form has only one input field then hitting enter in this field triggers form submit + * (`ngSubmit`) + * - if a form has 2+ input fields and no buttons or input[type=submit] then hitting enter + * doesn't trigger submit + * - if a form has one or more input fields and one or more buttons or input[type=submit] then + * hitting enter in any of the input fields will trigger the click handler on the *first* button or + * input[type=submit] (`ngClick`) *and* a submit handler on the enclosing form (`ngSubmit`) + * + * Any pending `ngModelOptions` changes will take place immediately when an enclosing form is + * submitted. Note that `ngClick` events will occur before the model is updated. Use `ngSubmit` + * to have access to the updated model. + * + * ## Animation Hooks + * + * Animations in ngForm are triggered when any of the associated CSS classes are added and removed. + * These classes are: `.ng-pristine`, `.ng-dirty`, `.ng-invalid` and `.ng-valid` as well as any + * other validations that are performed within the form. Animations in ngForm are similar to how + * they work in ngClass and animations can be hooked into using CSS transitions, keyframes as well + * as JS animations. + * + * The following example shows a simple way to utilize CSS transitions to style a form element + * that has been rendered as invalid after it has been validated: + * + * 
+ * //be sure to include ngAnimate as a module to hook into more
+ * //advanced animations
+ * .my-form {
+ *   transition:0.5s linear all;
+ *   background: white;
+ * }
+ * .my-form.ng-invalid {
+ *   background: red;
+ *   color:white;
+ * }
