AngularJS無法使用ng-repeat訪問控制器數據

我有一段應該使用ng-repeat顯示的註釋，但我無法訪問數據。AngularJS無法使用ng-repeat訪問控制器數據

調試後，我仍然無法訪問沒有修改控制器的數據！我對Angular真的很陌生，所以我很容易犯下愚蠢的錯誤。

HTML/JS

'use strict'; 
 

 
angular.module('commentsApp', [])  
 
     .controller('DishDetailController', ['$scope', function($scope) { 
 

 
      var dish={ 
 
          name:'Uthapizza', 
 
          image: 'images/uthapizza.png', 
 
          category: 'mains', 
 
          label:'Hot', 
 
          price:'4.99', 
 
          description:'A unique combination of Indian Uthappam (pancake) and Italian pizza, topped with Cerignola olives, ripe vine cherry tomatoes, Vidalia onion, Guntur chillies and Buffalo Paneer.',

這裏你的錯誤是entry對象表示dish.comments陣列中的一個對象，所以訪問數據，你只需要刪除comments部分

<div ng-app="commentsApp"> 
    <div ng-controller="DishDetailController"> 
    <div class="col-xs-9 col-xs-offset-1"> 
     <div class="blockquote" ng-repeat="entry in dish.comments"> 
     <blockquote> 
      <p>{{entry.rating}} Stars</p> 
      <p>{{entry.comment}}</p> 
      <footer>{{entry.author}}, {{entry.date | date}}</footer> 
     </blockquote> 
     </div> 
    </div> 
    </div> 
</div>

這個工作！非常感謝！ –

試試這個：

<div ng-app="commentsApp"> 
    <div ng-controller="DishDetailController"> 
    <div class="col-xs-9 col-xs-offset-1"> 
     <div class="blockquote" ng-repeat="entry in dish.comments"> 
     <blockquote> 
      <p>{{entry.rating}} Stars</p> 
      <p>{{entry.comment}}</p> 
      <footer>{{entry.author}}, {{entry.date | date}}</footer> 
     </blockquote> 
     </div> 
    </div> 
    </div> 
</div>

你需要更改您的代碼此

<div ng-app="commentsApp"> 
<div ng-controller="DishDetailController"> 
    <div class="col-xs-9 col-xs-offset-1"> 

    <div class="blockquote" ng-repeat="entry in dish.comments"> 
     <blockquote> 
     {{entry}} 
     <p>{{entry.rating}} Stars</p> 
     <p>{{entry.comments}}</p> 
     <footer>{{entry.author}}, {{entry.date | date}}</footer> 
    </blockquote> 
    </div> 
</div> 
</div>
