我正在开发Angular应用程序。我尝试使用ng-if并在 ng-repeat中 切换，但未成功。我有类似的数据：

   **[{"_id":"52fb84fac6b93c152d8b4569",
       "post_id":"52fb84fac6b93c152d8b4567",
       "user_id":"52df9ab5c6b93c8e2a8b4567",
       "type":"hoot",},  
      {"_id":"52fb798cc6b93c74298b4568",
       "post_id":"52fb798cc6b93c74298b4567",
       "user_id":"52df9ab5c6b93c8e2a8b4567",
       "type":"story",},        
      {"_id":"52fb7977c6b93c5c2c8b456b",
       "post_id":"52fb7977c6b93c5c2c8b456a",
       "user_id":"52df9ab5c6b93c8e2a8b4567",
       "type":"article",},**

$ scope.comments =上面提到的数据
和我的HTML一样：

   <div ng-repeat = "data in comments">
      <div ng-if="hoot == data.type">
          //differnt template with hoot data
       </div>
      <div ng-if="story == data.type">
          //differnt template with story data
       </div>
       <div ng-if="article == data.type">
          //differnt template with article data
       </div> 
   </div>

如何在Angular中实现此目标？
