我试图实现的基本上是“重复完成渲染”处理程序。我能够检测到何时完成,但是我不知道如何从中触发功能。
检查小提琴:http : //jsfiddle.net/paulocoelho/BsMqq/3/
JS
var module = angular.module('testApp', []) .directive('onFinishRender', function () { return { restrict: 'A', link: function (scope, element, attr) { if (scope.$last === true) { element.ready(function () { console.log("calling:"+attr.onFinishRender); // CALL TEST HERE! }); } } } }); function myC($scope) { $scope.ta = [1, 2, 3, 4, 5, 6]; function test() { console.log("test executed"); } }
的HTML
<div ng-app="testApp" ng-controller="myC"> <p ng-repeat="t in ta" on-finish-render="test()">{{t}}</p> </div>
答 :从finishmove的工作提琴:http : //jsfiddle.net/paulocoelho/BsMqq/4/
var module = angular.module('testApp', []) .directive('onFinishRender', function ($timeout) { return { restrict: 'A', link: function (scope, element, attr) { if (scope.$last === true) { $timeout(function () { scope.$emit(attr.onFinishRender); }); } } } });
请注意,我没有使用.ready(),而是将其包装在中$timeout。$timeout确保在ng重复元素真正完成渲染后$timeout执行(因为将会在当前摘要周期的末尾执行- 并且也会在$apply内部调用,与不同setTimeout)。因此,ng- repeat完成后,我们$emit将向外部范围(同级和父范围)发出事件。
.ready()
$timeout
$apply
setTimeout
ng- repeat
$emit
然后在您的控制器中,可以使用以下命令进行捕获$on:
$on
$scope.$on('ngRepeatFinished', function(ngRepeatFinishedEvent) { //you also get the actual event object //do stuff, execute functions -- whatever... });
使用html看起来像这样:
<div ng-repeat="item in items" on-finish-render="ngRepeatFinished"> <div>{{item.name}}}<div> </div>
