|
* This object provides a utility for producing rich Error messages within |
|
* Angular. It can be called as follows: |
|
* |
|
* var exampleMinErr = minErr('example'); |
|
* throw exampleMinErr('one', 'This {0} is {1}', foo, bar); |
|
* |
|
* The above creates an instance of minErr in the example namespace. The |
|
* resulting error will have a namespaced error code of example.one. The |
|
* resulting error will replace {0} with the value of foo, and {1} with the |
|
* value of bar. The object is not restricted in the number of arguments it can |
|
* take. |
|
* |
|
* If fewer arguments are specified than necessary for interpolation, the extra |
|
* interpolation markers will be preserved in the final string. |
|
* |
|
* Since data will be parsed statically during a build step, some restrictions |
|
* are applied with respect to how minErr instances are created and called. |
|
* Instances should have names of the form namespaceMinErr for a minErr created |
|
* using minErr('namespace') . Error codes, namespaces and template strings |
|
* should all be static strings, not variables or general expressions. |
|
* |
|
* @param {string} module The namespace to use for the new minErr instance. |
|
* @returns {function(string, string, ...): Error} instance |

|
* {@link angular.module module} name to load. |
|
* |
|
* @description |
|
* |
|
* Use this directive to **auto-bootstrap** an AngularJS application. The `ngApp` directive |
|
* designates the **root element** of the application and is typically placed near the root element |
|
* of the page - e.g. on the `<body>` or `<html>` tags. |
|
* |
|
* Only one AngularJS application can be auto-bootstrapped per HTML document. The first `ngApp` |
|
* found in the document will be used to define the root element to auto-bootstrap as an |
|
* application. To run multiple applications in an HTML document you must manually bootstrap them using |
|
* {@link angular.bootstrap} instead. AngularJS applications cannot be nested within each other. |
|
* |
|
* You can specify an **AngularJS module** to be used as the root module for the application. This |
|
* module will be loaded into the {@link AUTO.$injector} when the application is bootstrapped and |
|
* should contain the application code needed or have dependencies on other modules that will |
|
* contain the code. See {@link angular.module} for more information. |
|
* |
|
* In the example below if the `ngApp` directive were not placed on the `html` element then the |
|
* document would not be compiled, the `AppController` would not be instantiated and the `{{ a+b }}` |
|
* would not be resolved to `3`. |
|
* |
|
* `ngApp` is the easiest, and most common, way to bootstrap an application. |
|
* |
|
<example module="ngAppDemo"> |
|
<file name="index.html"> |
|
<div ng-controller="ngAppDemoController"> |
|
I can add: {{a}} + {{b}} = {{ a+b }} |
|
</div> |
|
</file> |
|
<file name="script.js"> |
|

|
* The `angular.module` is a global place for creating, registering and retrieving Angular |
|
* modules. |
|
* All modules (angular core or 3rd party) that should be available to an application must be |
|
* registered using this mechanism. |
|
* |

* existing module (the name passed as the first argument to `module`) is retrieved. |
|
* |
|
* |
|
* # Module |
|
* |
|
* A module is a collection of services, directives, filters, and configuration information. |
|
* `angular.module` is used to configure the {@link AUTO.$injector $injector}. |
|
* |
|
* <pre> |
|
* // Create a new module |
|
* var myModule = angular.module('myModule', []); |
|
* |
|
* // register a new service |
|
* myModule.value('appName', 'MyCoolApp'); |
|
* |
|
* // configure existing services inside initialization blocks. |
|
* myModule.config(function($locationProvider) { |
|
* // Configure existing providers |
|
* $locationProvider.hashPrefix('!'); |
|
* }); |
|
* </pre> |
|
* |
|
* Then you can create an injector and load your modules like this: |
|
* |
|
* <pre> |
|
* var injector = angular.injector(['ng', 'MyModule']) |
|
* </pre> |
|
* |
|
* However it's more likely that you'll just use |
|
* {@link ng.directive:ngApp ngApp} or |
|
* {@link angular.bootstrap} to simplify this process for you. |
|
* |
|
* @param {!string} name The name of the module to create or retrieve. |
|
* @param {Array.<string>=} requires If specified then new module is being created. If |
|
* unspecified then the the module is being retrieved for further configuration. |
|
* @param {Function} configFn Optional configuration function for the module. Same as |
|
* {@link angular.Module#methods_config Module#config()}. |
|
* @returns {module} new module with the {@link angular.Module} api. |

|
* @name angular.element |
|
* @function |
|
* |
|
* @description |
|
* Wraps a raw DOM element or HTML string as a [jQuery](http://jquery.com) element. |
|
* |
|
* If jQuery is available, `angular.element` is an alias for the |
|
* [jQuery](http://api.jquery.com/jQuery/) function. If jQuery is not available, `angular.element` |
|
* delegates to Angular's built-in subset of jQuery, called "jQuery lite" or "jqLite." |
|
* |
|
* <div class="alert alert-success">jqLite is a tiny, API-compatible subset of jQuery that allows |
|
* Angular to manipulate the DOM in a cross-browser compatible way. **jqLite** implements only the most |
|
* commonly needed functionality with the goal of having a very small footprint.</div> |
|
* |
|
* To use jQuery, simply load it before `DOMContentLoaded` event fired. |
|
* |
|
* <div class="alert">**Note:** all element references in Angular are always wrapped with jQuery or |
|
* jqLite; they are never raw DOM references.</div> |
|
* |
|
* ## Angular's jqLite |
|
* jqLite provides only the following jQuery methods: |
|
* |
|
* - [`addClass()`](http://api.jquery.com/addClass/) |
|
* - [`after()`](http://api.jquery.com/after/) |
|
* - [`append()`](http://api.jquery.com/append/) |
|
* - [`attr()`](http://api.jquery.com/attr/) |
|
* - [`bind()`](http://api.jquery.com/bind/) - Does not support namespaces, selectors or eventData |
|
* - [`children()`](http://api.jquery.com/children/) - Does not support selectors |
|
* - [`clone()`](http://api.jquery.com/clone/) |
|
* - [`contents()`](http://api.jquery.com/contents/) |
|
* - [`css()`](http://api.jquery.com/css/) |
|
* - [`data()`](http://api.jquery.com/data/) |
|
* - [`empty()`](http://api.jquery.com/empty/) |
|
* - [`eq()`](http://api.jquery.com/eq/) |
|
* - [`find()`](http://api.jquery.com/find/) - Limited to lookups by tag name |
|
* - [`hasClass()`](http://api.jquery.com/hasClass/) |
|
* - [`html()`](http://api.jquery.com/html/) |
|
* - [`next()`](http://api.jquery.com/next/) - Does not support selectors |
|
* - [`on()`](http://api.jquery.com/on/) - Does not support namespaces, selectors or eventData |
|
* - [`off()`](http://api.jquery.com/off/) - Does not support namespaces or selectors |
|
* - [`one()`](http://api.jquery.com/one/) - Does not support namespaces or selectors |
|
* - [`parent()`](http://api.jquery.com/parent/) - Does not support selectors |
|
* - [`prepend()`](http://api.jquery.com/prepend/) |
|
* - [`prop()`](http://api.jquery.com/prop/) |
|
* - [`ready()`](http://api.jquery.com/ready/) |
|
* - [`remove()`](http://api.jquery.com/remove/) |
|
* - [`removeAttr()`](http://api.jquery.com/removeAttr/) |
|
* - [`removeClass()`](http://api.jquery.com/removeClass/) |
|
* - [`removeData()`](http://api.jquery.com/removeData/) |
|
* - [`replaceWith()`](http://api.jquery.com/replaceWith/) |
|
* - [`text()`](http://api.jquery.com/text/) |
|
* - [`toggleClass()`](http://api.jquery.com/toggleClass/) |
|
* - [`triggerHandler()`](http://api.jquery.com/triggerHandler/) - Passes a dummy event object to handlers. |
|
* - [`unbind()`](http://api.jquery.com/unbind/) - Does not support namespaces |
|
* - [`val()`](http://api.jquery.com/val/) |
|
* - [`wrap()`](http://api.jquery.com/wrap/) |
|
* |
|
* ## jQuery/jqLite Extras |
|
* Angular also provides the following additional methods and events to both jQuery and jqLite: |
|
* |
|
* ### Events |
|
* - `$destroy` - AngularJS intercepts all jqLite/jQuery's DOM destruction apis and fires this event |
|
* on all DOM nodes being removed. This can be used to clean up any 3rd party bindings to the DOM |
|
* element before it is removed. |
|
* |
|
* ### Methods |
|
* - `controller(name)` - retrieves the controller of the current element or its parent. By default |
|
* retrieves controller associated with the `ngController` directive. If `name` is provided as |
|
* camelCase directive name, then the controller for this directive will be retrieved (e.g. |
|
* `'ngModel'`). |
|
* - `injector()` - retrieves the injector of the current element or its parent. |
|
* - `scope()` - retrieves the {@link api/ng.$rootScope.Scope scope} of the current |
|
* element or its parent. |
|
* - `isolateScope()` - retrieves an isolate {@link api/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. |
|
* - `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. |

|

|
|
|
* @param {Array.<string|Function>} modules A list of module functions or their aliases. See |

|
* @returns {function()} Injector function. See {@link AUTO.$injector $injector}. |
|
* |
|
* @example |
|
* Typical usage |
|
* <pre> |
|
* // create an injector |
|
* var $injector = angular.injector(['ng']); |
|
* |
|
* // use the injector to kick off your application |
|

|
* |
|
* Sometimes you want to get access to the injector of a currently running Angular app |

|
* |
|
* *This is fairly rare but could be the case if a third party library is injecting the |
|
* markup.* |
|
* |
|
* In the following example a new block of HTML containing a `ng-controller` |
|
* directive is added to the end of the document body by JQuery. We then compile and link |
|
* it into the current AngularJS scope. |
|
* |
|
* <pre> |
|
* var $div = $('<div ng-controller="MyCtrl">{{content.label}}</div>'); |

* # Injection Function Annotation |
|
* |
|
* JavaScript does not have annotations, and annotations are needed for dependency injection. The |
|
* following are all valid ways of annotating function with injection arguments and are equivalent. |
|
* |
|
* <pre> |
|
* // inferred (only works if code not minified/obfuscated) |
|
* $injector.invoke(function(serviceA){}); |
|
* |
|
* // annotated |
|
* function explicit(serviceA) {}; |
|
* explicit.$inject = ['serviceA']; |
|
* $injector.invoke(explicit); |
|
* |
|
* // inline |
|
* $injector.invoke(['serviceA', function(serviceA){}]); |
|
* </pre> |
|
* |
|
* ## Inference |
|
* |
|
* In JavaScript calling `toString()` on a function returns the function definition. The definition |
|
* can then be parsed and the function arguments can be extracted. *NOTE:* This does not work with |
|
* minification, and obfuscation tools since these tools change the argument names. |
|
* |
|
* ## `$inject` Annotation |
|
* By adding a `$inject` property onto a function the injection parameters can be specified. |
|
* |
|
* ## Inline |
|
* As an array of injection names, where the last item in the array is the function to call. |

|
* @description |
|
* Returns an array of service names which the function is requesting for injection. This API is |
|
* used by the injector to determine which services need to be injected into the function when the |
|
* function is invoked. There are three ways in which the function can be annotated with the needed |
|
* dependencies. |
|
* |
|
* # Argument names |
|
* |
|
* The simplest form is to extract the dependencies from the arguments of the function. This is done |
|
* by converting the function into a string using `toString()` method and extracting the argument |
|
* names. |
|
* <pre> |
|
* // Given |
|
* function MyController($scope, $route) { |
|
* // ... |
|
* } |
|
* |
|
* // Then |
|
* expect(injector.annotate(MyController)).toEqual(['$scope', '$route']); |
|
* </pre> |
|
* |
|
* This method does not work with code minification / obfuscation. For this reason the following |
|
* annotation strategies are supported. |
|
* |
|
* # The `$inject` property |
|
* |
|
* If a function has an `$inject` property and its value is an array of strings, then the strings |
|
* represent names of services to be injected into the function. |
|
* <pre> |
|
* // Given |
|
* var MyController = function(obfuscatedScope, obfuscatedRoute) { |
|
* // ... |
|
* } |
|
* // Define function dependencies |
|
* MyController['$inject'] = ['$scope', '$route']; |
|
* |
|
* // Then |
|
* expect(injector.annotate(MyController)).toEqual(['$scope', '$route']); |
|
* </pre> |
|
* |
|
* # The array notation |
|
* |
|
* It is often desirable to inline Injected functions and that's when setting the `$inject` property |
|
* is very inconvenient. In these situations using the array notation to specify the dependencies in |
|
* a way that survives minification is a better choice: |
|
* |
|
* <pre> |
|
* // We wish to write this (not minification / obfuscation safe) |
|
* injector.invoke(function($compile, $rootScope) { |
|
* // ... |
|
* }); |
|
* |
|
* // We are forced to write break inlining |
|
* var tmpFn = function(obfuscatedCompile, obfuscatedRootScope) { |
|
* // ... |
|
* }; |
|
* tmpFn.$inject = ['$compile', '$rootScope']; |
|
* injector.invoke(tmpFn); |
|
* |
|
* // To better support inline function the inline annotation is supported |
|
* injector.invoke(['$compile', '$rootScope', function(obfCompile, obfRootScope) { |
|
* // ... |
|
* }]); |
|
* |
|
* // Therefore |
|
* expect(injector.annotate( |
|
* ['$compile', '$rootScope', function(obfus_$compile, obfus_$rootScope) {}]) |
|
* ).toEqual(['$compile', '$rootScope']); |
|
* </pre> |
|
* |
|
* @param {function|Array.<string|Function>} fn Function for which dependent service names need to |
|
* be retrieved as described above. |
|
* |
|
* @returns {Array.<string>} The names of the services which the function requires. |

|

|
* The {@link AUTO.$provide $provide} service has a number of methods for registering components |
|
* with the {@link AUTO.$injector $injector}. Many of these functions are also exposed on |
|
* {@link angular.Module}. |
|
* |
|
* An Angular **service** is a singleton object created by a **service factory**. These **service |
|
* factories** are functions which, in turn, are created by a **service provider**. |
|
* The **service providers** are constructor functions. When instantiated they must contain a |
|
* property called `$get`, which holds the **service factory** function. |
|
* |
|
* When you request a service, the {@link AUTO.$injector $injector} is responsible for finding the |
|
* correct **service provider**, instantiating it and then calling its `$get` **service factory** |
|
* function to get the instance of the **service**. |
|
* |
|
* Often services have no configuration options and there is no need to add methods to the service |
|
* provider. The provider will be no more than a constructor function with a `$get` property. For |
|
* these cases the {@link AUTO.$provide $provide} service has additional helper methods to register |
|
* services without specifying a provider. |
|
* |
|
* * {@link AUTO.$provide#methods_provider provider(provider)} - registers a **service provider** with the |
|
* {@link AUTO.$injector $injector} |
|
* * {@link AUTO.$provide#methods_constant constant(obj)} - registers a value/object that can be accessed by |
|
* providers and services. |
|
* * {@link AUTO.$provide#methods_value value(obj)} - registers a value/object that can only be accessed by |
|
* services, not providers. |
|
* * {@link AUTO.$provide#methods_factory factory(fn)} - registers a service **factory function**, `fn`, |
|
* that will be wrapped in a **service provider** object, whose `$get` property will contain the |
|
* given factory function. |
|
* * {@link AUTO.$provide#methods_service service(class)} - registers a **constructor function**, `class` that |
|
* that will be wrapped in a **service provider** object, whose `$get` property will instantiate |
|
* a new object using the given constructor function. |

|
* |
|
* Register a **provider function** with the {@link AUTO.$injector $injector}. Provider functions |
|
* are constructor functions, whose instances are responsible for "providing" a factory for a |
|
* service. |
|
* |
|
* Service provider names start with the name of the service they provide followed by `Provider`. |
|
* For example, the {@link ng.$log $log} service has a provider called |
|
* {@link ng.$logProvider $logProvider}. |
|
* |
|
* Service provider objects can have additional methods which allow configuration of the provider |
|
* and its service. Importantly, you can configure what kind of service is created by the `$get` |
|
* method, or how that service will act. For example, the {@link ng.$logProvider $logProvider} has a |
|
* method {@link ng.$logProvider#debugEnabled debugEnabled} |
|
* which lets you specify whether the {@link ng.$log $log} service will log debug messages to the |
|
* console or not. |
|
* |
|
* @param {string} name The name of the instance. NOTE: the provider will be available under `name + |
|
'Provider'` key. |
|
* @param {(Object|function())} provider If the provider is: |
|
* |
|
* - `Object`: then it should have a `$get` method. The `$get` method will be invoked using |
|
* {@link AUTO.$injector#invoke $injector.invoke()} when an instance needs to be created. |
|
* - `Constructor`: a new instance of the provider will be created using |
|
* {@link AUTO.$injector#instantiate $injector.instantiate()}, then treated as `object`. |
|
* |

* Here are some examples of creating value services. |
|
* <pre> |
|
* $provide.value('ADMIN_USER', 'admin'); |
|
* |
|
* $provide.value('RoleLookup', { admin: 0, writer: 1, reader: 2 }); |

|
* @param {string} name The name of the service to decorate. |
|
* @param {function()} decorator This function will be invoked when the service needs to be |
|
* instantiated and should return the decorated service instance. The function is called using |
|
* the {@link AUTO.$injector#invoke injector.invoke} method and is therefore fully injectable. |
|
* Local injection arguments: |

* |
|
* * `$delegate` - The original service instance, which can be monkey patched, configured, |

|
* <pre> |
|
* <div ng-include=" 'templateId.html' "></div> |
|
* </pre> |
|
* |
|

* @description |
|
* Compiles an HTML string or DOM into a template and produces a template function, which |
|
* can then be used to link {@link ng.$rootScope.Scope `scope`} and the template together. |
|
* |
|
* The compilation is a process of walking the DOM tree and matching DOM elements to |
|
* {@link ng.$compileProvider#methods_directive directives}. |

|
* **Note:** This document is an in-depth reference of all directive options. |

* </div> |
|
* |
|
* ## 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). |
|
* |
|
* <div class="alert alert-success"> |
|
* **Best Practice:** It's recommended to use the "directive definition object" form. |
|
* </div> |
|
* |
|
* Here's an example directive declared with a Directive Definition Object: |
|
* |
|
* <pre> |
|
* var myModule = angular.module(...); |
|
* |
|
* myModule.directive('directiveName', function factory(injectables) { |
|
* var directiveDefinitionObject = { |
|
* priority: 0, |
|
* template: '<div></div>', // or // function(tElement, tAttrs) { ... }, |
|
* // or |
|
* // templateUrl: 'directive.html', // or // function(tElement, tAttrs) { ... }, |
|
* replace: false, |
|
* transclude: false, |
|
* restrict: 'A', |
|
* scope: false, |
|
* controller: function($scope, $element, $attrs, $transclude, otherInjectables) { ... }, |
|
* require: 'siblingDirectiveName', // or // ['^parentDirectiveName', '?optionalDirectiveName', '?^optionalParent'], |
|
* compile: function compile(tElement, tAttrs, transclude) { |
|
* return { |
|
* pre: function preLink(scope, iElement, iAttrs, controller) { ... }, |
|
* post: function postLink(scope, iElement, iAttrs, controller) { ... } |
|
* } |
|
* // or |
|
* // return function postLink( ... ) { ... } |
|
* }, |
|
* // or |
|
* // link: { |
|
* // pre: function preLink(scope, iElement, iAttrs, controller) { ... }, |
|
* // post: function postLink(scope, iElement, iAttrs, controller) { ... } |
|
* // } |
|
* // or |
|
* // link: function postLink( ... ) { ... } |
|
* }; |
|
* return directiveDefinitionObject; |
|
* }); |
|
* </pre> |
|
* |
|
* <div class="alert alert-warning"> |
|
* **Note:** Any unspecified options will use the default value. You can see the default values below. |
|
* </div> |
|
* |
|
* Therefore the above can be simplified as: |
|
* |
|
* <pre> |
|
* var myModule = angular.module(...); |
|
* |
|
* myModule.directive('directiveName', function factory(injectables) { |
|
* var directiveDefinitionObject = { |
|
* link: function postLink(scope, iElement, iAttrs) { ... } |
|
* }; |
|
* return directiveDefinitionObject; |
|
* // or |
|
* // return function postLink(scope, iElement, iAttrs) { ... } |
|
* }); |
|
* </pre> |
|
* |
|
* |
|
* |
|
* ### Directive Definition Object |
|
* |
|
* The directive definition object provides instructions to the {@link api/ng.$compile |
|
* compiler}. The attributes are: |
|
* |
|
* #### `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). |
|
* |
|
* #### `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 `<widget my-attr="hello {{name}}">` 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 `<widget my-attr="parentModel">` 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. |
|
* |
|
* * `&` 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 `<widget my-attr="count = count + value">` 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 and 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})`. |
|
* |
|
* |
|
* |
|
* #### `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. |
|
* The scope can be overridden by an optional first argument. |
|
* `function([scope], cloneLinkingFn)`. |
|
* |
|
* |
|
* #### `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. 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's parents. Throw an error 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` |
|
* Controller alias at the directive scope. An alias for the controller so it |
|
* can be referenced at 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 default (attributes only) is used. |
|
* |
|
* * `E` - Element name: `<my-directive></my-directive>` |
|
* * `A` - Attribute (default): `<div my-directive="exp"></div>` |
|
* * `C` - Class: `<div class="my-directive: exp;"></div>` |
|
* * `M` - Comment: `<!-- directive: my-directive exp -->` |
|
* |
|
* |
|
* #### `template` |
|
* replace the current element with the contents of the HTML. The replacement process |
|
* migrates all of the attributes / classes from the old element to the new one. See the |
|
* {@link guide/directive#creating-custom-directives_creating-directives_template-expanding-directive |
|
* Directives Guide} for an example. |
|
* |
|
* You can specify `template` as a string representing the template 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 template. |
|
* |
|
* |
|
* #### `templateUrl` |
|
* Same as `template` but the template is loaded from the specified URL. Because |
|
* the template loading is asynchronous the compilation/linking is suspended until the template |
|
* is loaded. |
|
* |
|
* 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 |
|
* api/ng.$sce#methods_getTrustedResourceUrl $sce.getTrustedResourceUrl}. |
|
* |
|
* |
|
* #### `replace` |
|
* specify where the template should be inserted. Defaults to `false`. |
|
* |
|
* * `true` - the template will replace the current element. |
|
* * `false` - the template will replace the contents of the current element. |
|
* |
|
* |
|
* #### `transclude` |
|
* compile the content of the element and make it available to the directive. |
|
* Typically used with {@link api/ng.directive:ngTransclude |
|
* ngTransclude}. The advantage of transclusion is that the linking function receives a |
|
* transclusion function which is pre-bound to the correct scope. In a typical setup the widget |
|
* creates an `isolate` scope, but the transclusion is not a child, but a sibling of the `isolate` |
|
* scope. This makes it possible for the widget to have private state, and the transclusion to |
|
* be bound to the parent (pre-`isolate`) scope. |
|
* |
|
* * `true` - transclude the content of the directive. |
|
* * `'element'` - transclude the whole element including any directives defined at lower priority. |
|
* |
|
* |
|
* #### `compile` |
|
* |
|
* <pre> |
|
* function compile(tElement, tAttrs, transclude) { ... } |
|
* </pre> |
|
* |
|
* The compile function deals with transforming the template DOM. Since most directives do not do |
|
* template transformation, it is not used often. Examples that require compile functions are |
|
* directives that transform template DOM, such as {@link |
|
* api/ng.directive:ngRepeat ngRepeat}, or load the contents |
|
* asynchronously, such as {@link api/ngRoute.directive:ngView ngView}. 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)` |
|
* |
|
* <div class="alert alert-warning"> |
|
* **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. |
|
* </div> |
|
* |
|
* <div class="alert alert-error"> |
|
* **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. |
|
* </div> |
|
|
|
* 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. |
|
* |
|
* <pre> |
|
* function link(scope, iElement, iAttrs, controller, transcludeFn) { ... } |
|
* </pre> |
|
* |
|
* 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 api/ng.$rootScope.Scope Scope} - The scope to be used by the |
|
* directive for registering {@link api/ng.$rootScope.Scope#methods_$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` - a controller instance - A controller instance if at least one directive on the |
|
* element defines a controller. The controller is shared among all the directives, which allows |
|
* the directives to use the controllers as a communication channel. |
|
* |
|
* * `transcludeFn` - A transclude linking function pre-bound to the correct transclusion scope. |
|
* The scope can be overridden by an optional first argument. This is the same as the `$transclude` |
|
* parameter of directive controllers. |
|
* `function([scope], cloneLinkingFn)`. |
|
* |
|
* |
|
* #### Pre-linking function |
|
* |
|
* Executed before the child elements are linked. Not safe to do DOM transformation since the |
|
* compiler linking function will fail to locate the correct elements for linking. |
|
* |
|
* #### Post-linking function |
|
* |
|
* Executed after the child elements are linked. It is safe to do DOM transformation in the post-linking function. |
|
* |
|
* <a name="Attributes"></a> |
|
* ### Attributes |
|
* |
|
* The {@link api/ng.$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 `$observe` to observe the value changes of attributes |
|
* that contain interpolation (e.g. `src="{{bar}}"`). Not only is this very efficient but it's also |
|
* the only way to easily get the actual value because during the linking phase the interpolation |
|
* hasn't been evaluated yet and so the value is at this time set to `undefined`. |
|
* |
|
* <pre> |
|
* function linkingFn(scope, elm, attrs, ctrl) { |
|
* // get the attribute value |
|
* console.log(attrs.ngModel); |
|
* |
|
* // change the attribute |
|
* attrs.$set('ngModel', 'new value'); |
|
* |
|
* // observe changes to interpolated attribute |
|
* attrs.$observe('ngModel', function(value) { |
|
* console.log('ngModel has changed value to ' + value); |
|
* }); |
|
* } |
|
* </pre> |
|
* |
|
* Below is an example using `$compileProvider`. |
|
* |
|
* <div class="alert alert-warning"> |
|
* **Note**: Typically directives are registered with `module.directive`. The example below is |
|
* to illustrate how `$compile` works. |

* @param {string|DOMElement} element Element or HTML string to compile into a template function. |
|
* @param {function(angular.Scope[, cloneAttachFn]} transclude function available to directives. |
|
* @param {number} maxPriority only apply directives lower then given priority (Only effects the |
|
* root element(s), not their children) |
|
* @returns {function(scope[, cloneAttachFn])} 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: <br> `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. |
|
* |
|
* 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. |
|
* <pre> |
|
* var element = $compile('<p>{{total}}</p>')(scope); |
|
* </pre> |
|
* |
|
* - if on the other hand, you need the element to be cloned, the view reference from the original |
|

* @description |
|
* The `$http` service is a core Angular service that facilitates communication with the remote |
|
* HTTP servers via the browser's {@link https://developer.mozilla.org/en/xmlhttprequest |
|
* XMLHttpRequest} object or via {@link http://en.wikipedia.org/wiki/JSONP JSONP}. |
|
* |
|
* For unit testing applications that use `$http` service, see |
|
* {@link ngMock.$httpBackend $httpBackend mock}. |
|
* |
|
* For a higher level of abstraction, please check out the {@link ngResource.$resource |
|
* $resource} service. |
|
* |
|
* The $http API is based on the {@link ng.$q deferred/promise APIs} exposed by |
|
* the $q service. While for simple usage patterns this doesn't matter much, for advanced usage |
|
* it is important to familiarize yourself with these APIs and the guarantees they provide. |
|
* |
|
* |
|
* # General usage |
|
* The `$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} |
|
* with two $http specific methods: `success` and `error`. |
|
* |
|
* <pre> |
|
* $http({method: 'GET', url: '/someUrl'}). |
|
* success(function(data, status, headers, config) { |
|
* // this callback will be called asynchronously |
|
* // when the response is available |
|
* }). |
|
* error(function(data, status, headers, config) { |
|
* // called asynchronously if an error occurs |
|
* // or server returns response with an error status. |
|
* }); |
|
* </pre> |
|
* |
|
* Since the returned value of calling the $http function is a `promise`, you can also use |
|
* the `then` method to register callbacks, and these callbacks will receive a single argument – |
|
* an object representing the response. See the API signature and type info below for more |
|
* details. |
|
* |
|
* 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 $http |
|
* When unit testing (using {@link api/ngMock ngMock}), it is necessary to call |
|
* {@link api/ngMock.$httpBackend#methods_flush $httpBackend.flush()} to flush each pending |
|
* request using trained responses. |
|
* |
|
* ``` |
|
* $httpBackend.expectGET(...); |
|
* $http.get(...); |
|
* $httpBackend.flush(); |
|
* ``` |
|
* |
|
* # Shortcut methods |
|
* |
|
* Since all invocations of the $http service require passing in an HTTP method and URL, and |
|
* POST/PUT requests require request data to be provided as well, shortcut methods |
|
* were created: |
|
* |
|
* <pre> |
|
* $http.get('/someUrl').success(successCallback); |
|
* $http.post('/someUrl', data).success(successCallback); |
|
* </pre> |
|
* |
|
* Complete list of shortcut methods: |
|
* |
|
* - {@link ng.$http#methods_get $http.get} |
|
* - {@link ng.$http#methods_head $http.head} |
|
* - {@link ng.$http#methods_post $http.post} |
|
* - {@link ng.$http#methods_put $http.put} |
|
* - {@link ng.$http#methods_delete $http.delete} |
|
* - {@link ng.$http#methods_jsonp $http.jsonp} |
|
* |
|
* |
|
* # 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) { |
|
* $http.defaults.headers.common.Authentication = 'Basic YmVlcDpib29w' |
|
* }); |
|
* ``` |
|
* |
|
* In addition, you can supply a `headers` property in the config object passed when |
|
* calling `$http(config)`, which overrides the defaults without changing them globally. |
|
* |
|
* |
|
* # Transforming Requests and Responses |
|
* |
|
* Both requests and responses can be transformed using transform functions. By default, Angular |
|
* applies these transformations: |
|
* |
|
* Request transformations: |
|
* |
|
* - If the `data` property of the request configuration object contains an object, serialize it |
|
* into JSON format. |
|
* |
|
* Response transformations: |
|
* |
|
* - If XSRF prefix is detected, strip it (see Security Considerations section below). |
|
* - If JSON response is detected, deserialize it using a JSON parser. |
|
* |
|
* To globally augment or override the default transforms, modify the |
|
* `$httpProvider.defaults.transformRequest` and `$httpProvider.defaults.transformResponse` |
|
* properties. These properties are by default an array of transform functions, which allows you |
|
* to `push` or `unshift` a new transformation function into the transformation chain. You can |
|
* also decide to completely override any default transformations by assigning your |
|
* transformation functions to these properties directly without the array wrapper. These defaults |
|
* are again available on the $http factory at run-time, which may be useful if you have run-time |
|
* services you wish to be involved in your transformations. |
|
* |
|
* Similarly, to locally override the request/response transforms, augment the |
|
* `transformRequest` and/or `transformResponse` properties of the configuration object passed |
|
* into `$http`. |
|
* |
|
* |
|
* # 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#properties_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 http `config` object. The function is free to |
|
* modify the `config` or create a new one. The function needs to return the `config` |
|
* directly or as a promise. |
|
* * `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` or create a new one. The function needs to return the `response` |
|
* directly or as a promise. |
|
* * `responseError`: interceptor gets called when a previous interceptor threw an error or |
|
* resolved with a rejection. |
|
* |
|
* |
|
* <pre> |
|
* // 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 || $q.when(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 || $q.when(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 |
|
* } |
|
* }; |
|
* }); |
|
* </pre> |
|
* |
|
* # Response interceptors (DEPRECATED) |
|
* |
|
* Before you start creating interceptors, be sure to understand the |
|
* {@link ng.$q $q and deferred/promise APIs}. |
|
* |
|
* For purposes of global error handling, authentication or any kind of synchronous or |
|
* asynchronous preprocessing of received responses, it is desirable to be able to intercept |
|
* responses for http requests before they are handed over to the application code that |
|
* initiated these requests. The response interceptors leverage the {@link ng.$q |
|
* promise apis} to fulfil this need for both synchronous and asynchronous preprocessing. |
|
* |
|
* The interceptors are service factories that are registered with the $httpProvider by |
|
* adding them to the `$httpProvider.responseInterceptors` array. The factory is called and |
|
* injected with dependencies (if specified) and returns the interceptor — a function that |
|
* takes a {@link ng.$q promise} and returns the original or a new promise. |
|
* |
|
* <pre> |
|
* // register the interceptor as a service |
|
* $provide.factory('myHttpInterceptor', function($q, dependency1, dependency2) { |
|
* return function(promise) { |
|
* return promise.then(function(response) { |
|
* // do something on success |
|
* return response; |
|
* }, function(response) { |
|
* // do something on error |
|
* if (canRecover(response)) { |
|
* return responseOrNewPromise |
|
* } |
|
* return $q.reject(response); |
|
* }); |
|
* } |
|
* }); |
|
* |
|
* $httpProvider.responseInterceptors.push('myHttpInterceptor'); |
|
* |
|
* |
|
* // register the interceptor via an anonymous factory |
|
* $httpProvider.responseInterceptors.push(function($q, dependency1, dependency2) { |
|
* return function(promise) { |
|
* // same as above |
|
* } |
|
* }); |
|
* </pre> |

* # Security Considerations |
|
* |
|
* When designing web applications, consider security threats from: |
|
* |
|
* - {@link http://haacked.com/archive/2008/11/20/anatomy-of-a-subtle-json-vulnerability.aspx |
|
* JSON vulnerability} |
|
* - {@link http://en.wikipedia.org/wiki/Cross-site_request_forgery XSRF} |
|
* |
|
* 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 {@link http://haacked.com/archive/2008/11/20/anatomy-of-a-subtle-json-vulnerability.aspx |
|
* JSON vulnerability} allows third party website to turn your JSON resource URL into |
|
* {@link http://en.wikipedia.org/wiki/JSONP 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: |
|
* <pre> |
|
* ['one','two'] |
|
* </pre> |
|
* |
|
* which is vulnerable to attack, your server can return: |
|
* <pre> |
|
* )]}', |
|
* ['one','two'] |
|
* </pre> |
|
* |
|
* Angular will strip the prefix, before processing the JSON. |
|
* |
|
* |
|
* ## Cross Site Request Forgery (XSRF) Protection |
|
* |
|
* {@link http://en.wikipedia.org/wiki/Cross-site_request_forgery XSRF} 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 {@link https://en.wikipedia.org/wiki/Salt_(cryptography) salt} |
|
* 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. |
|
* |
|
* |
|
* @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.<string|Object>}` – Map of strings or objects which will be turned |
|
* to `?key1=value1&key2=value2` after the url. If the value is not a string, it will be |
|
* JSONified. |
|
* - **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. |
|
* - **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.<function(data, headersGetter)>}` – |
|
* 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. |
|
* - **transformResponse** – |
|
* `{function(data, headersGetter)|Array.<function(data, headersGetter)>}` – |
|
* transform function or an array of such functions. The transform function takes the http |
|
* response body and headers and returns its transformed (typically deserialized) version. |
|
* - **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 to set the `withCredentials` flag on the |
|
* XHR object. See {@link https://developer.mozilla.org/en/http_access_control#section_5 |
|
* requests with credentials} for more information. |
|
* - **responseType** - `{string}` - see {@link |
|
* https://developer.mozilla.org/en-US/docs/DOM/XMLHttpRequest#responseType requestType}. |
|
* |
|
* @returns {HttpPromise} Returns a {@link ng.$q promise} object with the |
|
* standard `then` method and two http specific methods: `success` and `error`. The `then` |
|
* method takes two arguments a success and an error callback which will be called with a |
|
* response object. The `success` and `error` methods take a single argument - a function that |
|
* will be called when the request succeeds or fails respectively. The arguments passed into |
|
* these functions are destructured representation of the response object passed into the |
|
* `then` method. 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. |
|
* |
|
* @property {Array.<Object>} pendingRequests Array of config objects for currently pending |
|
* requests. This is primarily meant to be used for debugging purposes. |

|
* Angular's wrapper for `window.setInterval`. The `fn` function is executed every `delay` |
|
* milliseconds. |
|
* |
|
* The return value of registering an interval function is a promise. This promise will be |
|
* notified upon each tick of the interval, and will be resolved after `count` iterations, or |
|
* run indefinitely if `count` is not defined. The value of the notification will be the |
|
* number of iterations that have run. |
|
* To cancel an interval, call `$interval.cancel(promise)`. |
|
* |
|
* In tests you can use {@link ngMock.$interval#methods_flush `$interval.flush(millis)`} to |
|
* move forward by `millis` milliseconds and trigger any functions scheduled to run in that |
|
* time. |
|
* |
|

|
* **Note**: Intervals created by this service must be explicitly destroyed when you are finished |
|
* with them. In particular they are not automatically destroyed when a controller's scope or a |
|
* directive's element are destroyed. |
|
* You should take this into consideration and make sure to always cancel the interval at the |
|
* appropriate moment. See the example below for more details on how and when to do this. |

* @param {boolean=} [invokeApply=true] If set to `false` skips model dirty checking, otherwise |
|

// Sandboxing Angular Expressions |
|
// ------------------------------ |
|
// Angular expressions are generally considered safe because these expressions only have direct |
|
// access to $scope and locals. However, one can obtain the ability to execute arbitrary JS code by |
|
// obtaining a reference to native JS functions such as the Function constructor. |
|
// |
|
// As an example, consider the following Angular expression: |
|
// |
|
// {}.toString.constructor(alert("evil JS code")) |
|
// |
|
// We want to prevent this type of access. For the sake of performance, during the lexing phase we |
|
// disallow any "dotted" access to any member named "constructor". |
|
// |
|
// For reflective calls (a[b]) we check that the value of the lookup is not the Function constructor |
|
// while evaluating the expression, which is a stronger but more expensive test. Since reflective |
|
// calls are expensive anyway, this is not such a big deal compared to static dereferencing. |
|
// |
|
// This sandboxing technique is not perfect and doesn't aim to be. The goal is to prevent exploits |
|
// against the expression language, but not to prevent exploits that were enabled by exposing |
|
// sensitive JavaScript or browser apis on Scope. Exposing such objects on a Scope is never a good |
|
// practice and therefore we are not even trying to protect against interaction with an object |
|
// explicitly exposed in this way. |
|
// |
|
// A developer could foil the name check by aliasing the Function constructor under a different |
|
// name on the scope. |
|
// |
|
// In general, it is not possible to access a Window object from an angular expression unless a |
|
// window or some DOM object that has a reference to window is published onto a Scope. |
