私はAngularアプリに取り組んでいます。ng-if を使用してng-repeat内で切り替えようとしましたが、成功しませんでした。次のようなデータがあります。

   **[{"_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 = 上記のデータ
と私の Html のようなもの: 

   <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>

Angularでこれを達成するにはどうすればよいですか?

strings( hoot, story, article) を引用符で囲みます':

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

すべてのテンプレートを別のファイルに移動し、繰り返し内でスパゲッティを行わないことをお勧めします

ここを見てください：

html:

<div ng-repeat = "data in comments">
    <div ng-include src="buildUrl(data.type)"></div>
 </div>

js:

var app = angular.module('plunker', []);
app.controller('MainCtrl', function($scope) {

  $scope.comments = [
    {"_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.buildUrl = function(type) {
    return type + '.html';
  }
});
