This is to disallow changing the behaviour of existing functions in an unforeseen fashion.</p> <ul> <li>due to <a href="https://github.com/angular/angular.js/commit/6081f20769e64a800ee8075c168412b21f026d99">6081f207</a>,</li> </ul> <p>The (deprecated) <strong>proto</strong> property does not work inside angular expressions anymore.</p> <ul> <li>due to <a href="https://github.com/angular/angular.js/commit/48fa3aadd546036c7e69f71046f659ab1de244c6">48fa3aad</a>,</li> </ul> <p>This prevents the use of <strong>{define,lookup}{Getter,Setter}</strong> inside angular expressions. If you really need them for some reason, please wrap/bind them to make them less dangerous, then make them available through the scope object.</p> <ul> <li>due to <a href="https://github.com/angular/angular.js/commit/528be29d1662122a34e204dd607e1c0bd9c16bbc">528be29d</a>,</li> </ul> <p>This prevents the use of <code>Object</code> inside angular expressions. If you need Object.keys, make it accessible in the scope.</p> <ul> <li>due to <a href="https://github.com/angular/angular.js/commit/bdfc9c02d021e08babfbc966a007c71b4946d69d">bdfc9c02</a>, values 'f', '0', 'false', 'no', 'n', '[]' are no longer treated as falsy. Only JavaScript falsy values are now treated as falsy by the expression parser; there are six of them: false, null, undefined, NaN, 0 and "".</li> </ul> <ul> <li>due to <a href="https://github.com/angular/angular.js/commit/fa6e411da26824a5bae55f37ce7dbb859653276d">fa6e411d</a>, promise unwrapping has been removed. It has been deprecated since 1.2.0-rc.3. It can no longer be turned on. Two methods have been removed:<ul> <li><code>$parseProvider.unwrapPromises</code></li> <li><code>$parseProvider.logPromiseWarnings</code></li> </ul> </li> </ul> <ul> <li><p><strong>$interpolate:</strong> due to <a href="https://github.com/angular/angular.js/commit/88c2193c71954b9e7e7e4bdf636a2b168d36300d">88c2193c</a>, the function returned by <code>$interpolate</code> no longer has a <code>.parts</code> array set on it.</p> <p>Instead it has two arrays:</p> <ul> <li><code>.expressions</code>, an array of the expressions in the interpolated text. The expressions are parsed with <code>$parse</code>, with an extra layer converting them to strings when computed</li> <li><code>.separators</code>, an array of strings representing the separations between interpolations in the text. This array is <strong>always</strong> 1 item longer than the <code>.expressions</code> array for easy merging with it</li> </ul> </li> </ul> <h2 id="miscellaneous-angular-helpers">Miscellaneous Angular helpers</h2> <ul> <li><strong>Angular.copy:</strong> due to <a href="https://github.com/angular/angular.js/commit/b59b04f98a0b59eead53f6a53391ce1bbcbe9b57">b59b04f9</a>,</li> </ul> <p>This changes <code>angular.copy</code> so that it applies the prototype of the original object to the copied object. Previously, <code>angular.copy</code> would copy properties of the original object's prototype chain directly onto the copied object.</p> <p>This means that if you iterate over only the copied object's <code>hasOwnProperty</code> properties, it will no longer contain the properties from the prototype. This is actually much more reasonable behaviour and it is unlikely that applications are actually relying on this.</p> <p>If this behaviour is relied upon, in an app, then one should simply iterate over all the properties on the object (and its inherited properties) and not filter them with <code>hasOwnProperty</code>.</p> <p><strong>Be aware that this change also uses a feature that is not compatible with IE8.</strong> If you need this to work on IE8 then you would need to provide a polyfill for <code>Object.create</code> and <code>Object.getPrototypeOf</code>.</p> <ul> <li><strong>forEach:</strong> due to <a href="https://github.com/angular/angular.js/commit/55991e33af6fece07ea347a059da061b76fc95f5">55991e33</a>, forEach will iterate only over the initial number of items in the array. So if items are added to the array during the iteration, these won't be iterated over during the initial forEach call.</li> </ul> <p>This change also makes our forEach behave more like Array#forEach.</p> <ul> <li><strong>angular.toJson:</strong> due to <a href="https://github.com/angular/angular.js/commit/c054288c9722875e3595e6e6162193e0fb67a251">c054288c</a>,</li> </ul> <p>If you expected <code>toJson</code> to strip these types of properties before, you will have to manually do this yourself now.</p> <h2 id="jqlite-jquery">jqLite / JQuery</h2> <ul> <li><strong>jqLite:</strong> due to <a href="https://github.com/angular/angular.js/commit/a196c8bca82a28c08896d31f1863cf4ecd11401c">a196c8bc</a>, previously it was possible to set jqLite data on Text/Comment nodes, but now that is allowed only on Element and Document nodes just like in jQuery. We don't expect that app code actually depends on this accidental feature.</li> </ul> <ul> <li><strong>jqLite:</strong> due to <a href="https://github.com/angular/angular.js/commit/d71dbb1ae50f174680533492ce4c7db3ff74df00">d71dbb1a</a>, the jQuery <code>detach()</code> method does not trigger the <code>$destroy</code> event. If you want to destroy Angular data attached to the element, use <code>remove()</code>.</li> </ul> <h2 id="angular-html-compiler-compile-">Angular HTML Compiler (<code>$compile</code>)</h2> <ul> <li>due to <a href="https://github.com/angular/angular.js/commit/2ee29c5da81ffacdc1cabb438f5d125d5e116cb9">2ee29c5d</a>,</li> </ul> <p>The isolated scope of a component directive no longer leaks into the template that contains the instance of the directive. This means that you can no longer access the isolated scope from attributes on the element where the isolated directive is defined.</p> <p>See <a href="https://github.com/angular/angular.js/issues/10236">https://github.com/angular/angular.js/issues/10236</a> for an example.</p> <ul> <li>due to <a href="https://github.com/angular/angular.js/commit/2cde927e58c8d1588569d94a797e43cdfbcedaf9">2cde927e</a>,</li> </ul> <p>Requesting isolate scope and any other scope on a single element is an error. Before this change, the compiler let two directives request a child scope and an isolate scope if the compiler applied them in the order of non-isolate scope directive followed by isolate scope directive.</p> <p>Now the compiler will error regardless of the order.</p> <p>If you find that your code is now throwing a <code>$compile:multidir</code> error, check that you do not have directives on the same element that are trying to request both an isolate and a non-isolate scope and fix your code.</p> <ul> <li>due to <a href="https://github.com/angular/angular.js/commit/eec6394a342fb92fba5270eee11c83f1d895e9fb">eec6394a</a>, The <code>replace</code> flag for defining directives that replace the element that they are on will be removed in the next major angular version. This feature has difficult semantics (e.g. how attributes are merged) and leads to more problems compared to what it solves. Also, with Web Components it is normal to have custom elements in the DOM.</li> </ul> <ul> <li>due to <a href="https://github.com/angular/angular.js/commit/299b220f5e05e1d4e26bfd58d0b2fd7329ca76b1">299b220f</a>, calling <code>attr.$observe</code> no longer returns the observer function, but a deregistration function instead. To migrate the code follow the example below:</li> </ul> <p>Before:</p> <pre><code>directive('directiveName', function() { return { link: function(scope, elm, attr) { var observer = attr.$observe('someAttr', function(value) { console.log(value); }); } }; }); </code></pre> <p>After:</p> <pre><code>directive('directiveName', function() { return { link: function(scope, elm, attr) { var observer = function(value) { console.log(value); }; attr.$observe('someAttr', observer); } }; }); </code></pre> <h2 id="forms-inputs-and-ngmodel">Forms, Inputs and ngModel</h2> <ul> <li>due to <a href="https://github.com/angular/angular.js/commit/1be9bb9d3527e0758350c4f7417a4228d8571440">1be9bb9d</a>,</li> </ul> <p>If an expression is used on ng-pattern (such as <code>ng-pattern="exp"</code>) or on the pattern attribute (something like on <code>pattern="{{ exp }}"</code>) and the expression itself evaluates to a string then the validator will not parse the string as a literal regular expression object (a value like <code>/abc/i</code>). Instead, the entire string will be created as the regular expression to test against. This means that any expression flags will not be placed on the RegExp object. To get around this limitation, use a regular expression object as the value for the expression.</p> <pre><code>//before $scope.exp = '/abc/i'; //after $scope.exp = /abc/i; </code></pre> <ul> <li><strong>ngModelOptions:</strong> due to <a href="https://github.com/angular/angular.js/commit/adfc322b04a58158fb9697e5b99aab9ca63c80bb">adfc322b</a>,</li> </ul> <p>This commit changes the API on <code>NgModelController</code>, both semantically and in terms of adding and renaming methods.</p> <ul> <li><code>$setViewValue(value)</code> - This method still changes the <code>$viewValue</code> but does not immediately commit this change through to the <code>$modelValue</code> as it did previously. Now the value is committed only when a trigger specified in an associated <code>ngModelOptions</code> directive occurs. If <code>ngModelOptions</code> also has a <code>debounce</code> delay specified for the trigger then the change will also be debounced before being committed. In most cases this should not have a significant impact on how <code>NgModelController</code> is used: If <code>updateOn</code> includes <code>default</code> then <code>$setViewValue</code> will trigger a (potentially debounced) commit immediately.</li> <li><code>$cancelUpdate()</code> - is renamed to <code>$rollbackViewValue()</code> and has the same meaning, which is to revert the current <code>$viewValue</code> back to the <code>$lastCommittedViewValue</code>, to cancel any pending debounced updates and to re-render the input.</li> </ul> <p>To migrate code that used <code>$cancelUpdate()</code> follow the example below:</p> <p>Before:</p> <pre><code class="lang-js">$scope.resetWithCancel = function (e) { if (e.keyCode == 27) { $scope.myForm.myInput1.$cancelUpdate(); $scope.myValue = ''; } }; </code></pre> <p>After:</p> <pre><code class="lang-js">$scope.resetWithCancel = function (e) { if (e.keyCode == 27) { $scope.myForm.myInput1.$rollbackViewValue(); $scope.myValue = ''; } } </code></pre> <ul> <li>types date, time, datetime-local, month, week now always require a <code>Date</code> object as model (<a href="https://github.com/angular/angular.js/commit/46bd6dc88de252886d75426efc2ce8107a5134e9">46bd6dc8</a>, <a href="https://github.com/angular/angular.js/issues/5864">#5864</a>)</li> </ul> <h2 id="scopes-and-digests-scope-">Scopes and Digests (<code>$scope</code>)</h2> <ul> <li>due to <a href="https://github.com/angular/angular.js/commit/8c6a8171f9bdaa5cdabc0cc3f7d3ce10af7b434d">8c6a8171</a>, Scope#$id is now of type number rather than string.

If any code depends on asynchronously accessing their <code>currentScope</code> property, it should be migrated to use <code>targetScope</code> instead. All of these cases should be considered programming bugs.</li> </ul> <h2 id="server-requests-http-resource-">Server Requests (<code>$http</code>, <code>$resource</code>)</h2> <ul> <li><strong>$http:</strong> due to <a href="https://github.com/angular/angular.js/commit/ad4336f9359a073e272930f8f9bcd36587a8648f">ad4336f9</a>,</li> </ul> <p>Previously, it was possible to register a response interceptor like so:</p> <pre><code class="lang-js">// 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); }); } }); $httpProvider.responseInterceptors.push('myHttpInterceptor'); </code></pre> <p>Now, one must use the newer API introduced in v1.1.4 (4ae46814), like so:</p> <pre><code class="lang-js">$provide.factory('myHttpInterceptor', function($q) { return { response: function(response) { // do something on success return response; }, responseError: function(response) { // do something on error if (canRecover(response)) { return responseOrNewPromise } return $q.reject(response); } }; }); $httpProvider.interceptors.push('myHttpInterceptor'); </code></pre> <p>More details on the new interceptors API (which has been around as of v1.1.4) can be found at <a href="api/ng/service/$http#interceptors">interceptors</a></p> <ul> <li><strong>$httpBackend:</strong> due to <a href="https://github.com/angular/angular.js/commit/6680b7b97c0326a80bdccaf0a35031e4af641e0e">6680b7b9</a>, the JSONP behavior for erroneous and empty responses changed: Previously, a JSONP response was regarded as erroneous if it was empty.

Now, provider registration always occurs prior to configuration for a given module, and therefore config blocks are not able to have any control over a providers registration.</p> <p><strong>Example</strong>:</p> <p>Previously, the following:</p> <pre><code class="lang-js">angular.module('foo', []) .provider('$rootProvider', function() { this.$get = function() { ... } }) .config(function($rootProvider) { $rootProvider.dependentMode = "B"; }) .provider('$dependentProvider', function($rootProvider) { if ($rootProvider.dependentMode === "A") { this.$get = function() { // Special mode! } } else { this.$get = function() { // something else } } }); </code></pre> <p>would have "worked", meaning behaviour of the config block between the registration of "$rootProvider" and "$dependentProvider" would have actually accomplished something and changed the behaviour of the app. This is no longer possible within a single module.</p> <h2 id="animation-nganimate-">Animation (<code>ngAnimate</code>)</h2> <ul> <li>due to <a href="https://github.com/angular/angular.js/commit/1cb8584e8490ecdb1b410a8846c4478c6c2c0e53">1cb8584e</a>, <code>$animate</code> will no longer default the after parameter to the last element of the parent container.

In other words if your animation code is expecting any styling to be applied that is defined in the setup class then it will not be applied "instantly" unless a <code>transition:0s none</code> value is present in the styling for that CSS class. This situation is only the case if a transition is already present on the base CSS class once the animation kicks off.</p> </li> </ul> <p>Before:</p> <pre><code>.animated.my-class-add { opacity:0; transition:0.5s linear all; } .animated.my-class-add.my-class-add-active { opacity:1; } </code></pre> <p>After:</p> <pre><code>.animated.my-class-add { transition:0s linear all; opacity:0; } .animated.my-class-add.my-class-add-active { transition:0.5s linear all; opacity:1; } </code></pre> <p>Please view the documentation for ngAnimate for more info.</p> <h2 id="testing">Testing</h2> <ul> <li>due to <a href="https://github.com/angular/angular.js/commit/85880a64900fa22a61feb926bf52de0965332ca5">85880a64</a>, some deprecated features of Protractor tests no longer work.</li> </ul> <p><code>by.binding(descriptor)</code> no longer allows using the surrounding interpolation markers in the descriptor (the default interpolation markers are <code>{{}}</code>).

In Angular 1.0, if a directive with an isolate scope is used on an element, all directives on that same element have access to the same isolate scope. For example, say we have the following directives:</p> <pre><code>// This directive declares an isolate scope. .directive('isolateScope', function() { return { scope: {}, link: function($scope) { console.log('one = ' + $scope.$id); } }; }) // This directive does not. .directive('nonIsolateScope', function() { return { link: function($scope) { console.log('two = ' + $scope.$id); } }; }); </code></pre> <p>Now what happens if we use both directives on the same element?</p> <pre><code><div isolate-scope non-isolate-scope></div> </code></pre> <p>In Angular 1.0, the nonIsolateScope directive will have access to the isolateScope directive’s scope. The log statements will print the same id, because the scope is the same. But in Angular 1.2, the nonIsolateScope will not use the same scope as isolateScope. Instead, it will inherit the parent scope. The log statements will print different id’s.</p> <p>If your code depends on the Angular 1.0 behavior (non-isolate directive needs to access state from within the isolate scope), change the isolate directive to use scope locals to pass these explicitly:</p> <p><strong>Before</strong></p> <pre><code><input ng-model="$parent.value" ng-isolate> .directive('ngIsolate', function() { return { scope: {}, template: '{{value}}' }; }); </code></pre> <p><strong>After</strong></p> <pre><code><input ng-model="value" ng-isolate> .directive('ngIsolate', function() { return { scope: {value: '=ngModel'}, template: '{{value}} }; }); </code></pre> <p>See <a href="https://github.com/angular/angular.js/commit/909cabd36d779598763cc358979ecd85bb40d4d7">909cabd3</a>, <a href="https://github.com/angular/angular.js/issues/1924">#1924</a> and <a href="https://github.com/angular/angular.js/issues/2500">#2500</a>.</p> <h2 id="change-to-interpolation-priority">Change to interpolation priority</h2> <p>Previously, the interpolation priority was <code>-100</code> in 1.2.0-rc.2, and <code>100</code> before 1.2.0-rc.2.

These properties will not be available to Angular expressions (i.e. {{ }} interpolation in templates and strings passed to <code>$parse</code>) They are freely available to JavaScript code (as before).</p> <p><strong>Motivation</strong></p> <p>Angular expressions execute in a limited context. They do not have direct access to the global scope, <code>window</code>, <code>document</code> or the Function constructor. However, they have direct access to names/properties on the scope chain. It has been a long standing best practice to keep sensitive APIs outside of the scope chain (in a closure or your controller.) That's easier said than done for two reasons:</p> <ol> <li>JavaScript does not have a notion of private properties so if you need someone on the scope chain for JavaScript use, you also expose it to Angular expressions</li> <li>The new <code>controller as</code> syntax that's now in increased usage exposes the entire controller on the scope chain greatly increasing the exposed surface.</li> </ol> <p>Though Angular expressions are written and controlled by the developer, they:</p> <ol> <li>Typically deal with user input</li> <li>Don't get the kind of test coverage that JavaScript code would</li> </ol> <p>This commit provides a way, via a naming convention, to allow restricting properties from controllers/scopes. This means Angular expressions can access only those properties that are actually needed by the expressions.</p> <p>See <a href="https://github.com/angular/angular.js/commit/3d6a89e8888b14ae5cb5640464e12b7811853c7e">3d6a89e8</a>.</p> <h2 id="you-cannot-bind-to-select-multiple-">You cannot bind to select[multiple]</h2> <p>Switching between <code>select[single]</code> and <code>select[multiple]</code> has always been odd due to browser quirks.
