Is there a way to get the raw DOM element from an angular.element

阅读更多关于 Is there a way to get the raw DOM element from an angular.element

问题 angular.element All element references in Angular are always wrapped with jQuery or jqLite; they are never raw DOM references. How can I get the raw DOM element, because I have legacy JS code (jscolor Picker) that needs the raw DOM element? 回答1: Found it: ang_element = angular.element(element); raw_element = ang_element[0]; 来源： https://stackoverflow.com/questions/18302493/is-there-a-way-to-get-the-raw-dom-element-from-an-angular-element

AngularJS element.innerHTML is undefined from within directive

阅读更多关于 AngularJS element.innerHTML is undefined from within directive

Let's say I have: directives.directive('foo', function () { return { restrict:'A', scope: true, link:function (scope, element, attr) { console.log('innerHTML is ' + element.innerHTML); scope.$watch('update', function (newValue) { console.log('innerHTML is... ' + element.innerHTML); }); } } }); ... then innerHTML is undefined. I imagine this is due to the way Angular processes the DOM. What is the right way to obtain the innerHTML? The element variable that is passed to your link function is a jqLite object - not a DOM object. You can obtain the DOM object with element[0] (like you could in

阅读更多关于 AngularJS directives - best practices when using ngModel with jQuery widget

Modifying DOM (slideDown/slideUp) with AngularJS and jQuery

阅读更多关于 Modifying DOM (slideDown/slideUp) with AngularJS and jQuery

问题 I'm trying to implement a slideDown/slideUp animation with AngularJS. I can't use CSS3's transition (unfortunately) since the height is set to auto (and I don't want to use the max-height workaround), so I'm trying to use jQuery's slideToggle method. Given the following markup: <ul> <li ng-repeat="entry in data"> <span>{{entry.title}}</span> <a ng-click="clicked($event)" href>more?</a> <p>{{entry.description}}</p> </li> </ul> I implemented the following method in my controller: $scope.clicked

AngularJS : transcluding multiple sub elements in a single Angular directive

阅读更多关于 AngularJS : transcluding multiple sub elements in a single Angular directive

问题 I am Fairly new to Angular but have been reading quite a lot. I was reading about ng-transclude at http://docs.angularjs.org/guide/directive#creating-custom-directives_demo_isolating-the-scope-of-a-directive and I think I understand properly what it does. If you have a directive that applies to an element that has content inside it such as in <my-directive>directive content</my-directive> It will allow you to tag an element within the directive's template with ng-transclude and the content

Change Angular directive element attribute dynamically

阅读更多关于 Change Angular directive element attribute dynamically

问题 I am trying to create a custom directive which extends the functionality of an existing element. I would like to detect if a certain attribute exists and if not then add it (e.g. ng-class). I have tried to achieve this during pre-compilation but angular does not react to the addition of the new attribute. I created a plunker with a simple example using ng-hide. <input hide type="submit" value="Submit"/> app.directive('hide', function() { return { restrict: 'A', compile: function(){ return {
