本文实例讲述了AngularJS监听ng-repeat渲染完成的两种方法。分享给大家供大家参考，具体如下：

监听ng-repeat渲染完成有两种方法

一、最实用的方法:

<ul class="pprt_content">
    <li ng-repeat="src in imageHotList track by $index" ng-click='goGoodsDet(src.goodsId,src.merchId)' on-finish-render-filters="completeRepeat">
      <img ng-src="/UploadFiles/2021-04-02/{{productUrl}}{{src.imageName}}">

对应作用域controller:


$scope.completeRepeate= function(){
alert('1')
}




自定义指令directive:


var app = angular.moduler('myApp',[]);
app.directive('onFinishRenderFilters', ['$timeout', function ($timeout) {
    return {
      restrict: 'A',
      link: function(scope,element,attr) {
        if (scope.$last === true) {
          var finishFunc=scope.$parent[attr.onFinishRenderFilters];
          if(finishFunc)
          {
            finishFunc();
          }
        }
      }
    };
}])




二、使用广播事件


/*
* Controller文件中的代码
* Setup general page controller
*/
MetronicApp.controller('simpleManageController', ['$rootScope',
'$scope', 'settings','$http', function($rootScope, $scope, settings,$http) {
  $scope.$on('ngRepeatFinished', function (ngRepeatFinishedEvent) {
    //下面是在table render完成后执行的js
    FormEditable.init();
    Metronic.stopPageLoading();
    $(".simpleTab").show();
  });
});
MetronicApp.directive('onFinishRenderFilters', function ($timeout) {
  return {
    restrict: 'A',
    link: function(scope,element,attr) {
      if (scope.$last === true) {
        $timeout(function() {
          scope.$emit('ngRepeatFinished');
        });
      }
    }
  };
});




HTML


<!--HTML页面的代码，添加标签onFinishRenderFilters(格式有变)：on-finish-render-filters-->
 <tr style="display: none" class="simpleTab" ng-repeat="simpleProduct in simpleProducts"
   on-finish-render-filters>
     <td>
       {{simpleProduct.productNo}}
     </td>
</tr>
