使用 Angular.js 对下拉值进行排序时出现意外错误

Question

我在使用 Angular.js 按字母顺序对下拉值进行排序时遇到了一些错误。我在下面提供我的代码：

<div ng-dropdown-multiselect="" options="example16data | orderBy:'label'" selected-model="example16model" checkboxes="true" extra-settings="example16settings" class="form-control"></div>

 angular.forEach(response.data,function(obj){
      var data={'label':obj.cat_name+':'+obj.subcat_name,'id':obj.subcat_id};
      $scope.example16data.push(data);
 })

我在这里使用 Anguar 的 angularjs-dropdown-multiselect 作为下拉列表，但是当我尝试对列表进行排序时，出现以下意外错误。

你可以在你的代码中添加一个 $timeout 函数，只有我们可以避免 Angularjs 中的摘要循环。

You can remove your orderBy in HTML and apply the bellow login to the

$scope.$example16data = $filter("orderBy")($scope.example16data, 
"label")
