我想要实现的基本上是一个“on ng 重复完成渲染”处理程序。我能够检测到它何时完成,但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) { $scope.ta = [1, 2, 3, 4, 5, 6]; function test() { console.log("test executed"); } }
HTML
<div ng-app="testApp" ng-controller="myC"> <p ng-repeat="t in ta" on-finish-render="test()">{{t}}</p> </div>
答案 :finishmove 的工作小提琴:http: //jsfiddle.net/paulocoelho/BsMqq/4/
var module = angular.module(‘testApp’, []) .directive(‘onFinishRender’, function ($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$timeout. $timeout确保它在 ng-repeated 元素真正完成渲染$timeout时执行(因为它将在当前摘要周期结束时执行—— 它也会在$apply内部调用,不像setTimeout)。因此,在ng- repeat完成后,我们使用$emit向外部范围(兄弟范围和父范围)发出事件。
.ready()
$timeout
$apply
setTimeout
ng- repeat
$emit
然后在您的控制器中,您可以使用以下命令捕获它$on:
$on
$scope.$on('ngRepeatFinished', function(ngRepeatFinishedEvent) { //you also get the actual event object //do stuff, execute functions -- whatever... });
使用看起来像这样的 html:
<div ng-repeat="item in items" on-finish-render="ngRepeatFinished"> <div>{{item.name}}}<div> </div>
