我不知道为什么 ng-repeat 在我的代码中不起作用

Question

I am a newbie in angular and ionic and had been following a tutorial.我是 angular 和 ionic 的新手，一直在学习教程。 I tried the example code that is working just fine in the tutorial but not with me.我尝试了在教程中运行良好的示例代码，但不适用于我。 The issue is with the ng-repeat directive.问题在于 ng-repeat 指令。 Here is the code:这是代码：

<body ng-app="starter">
  <ion-pane>
    <ion-header-bar class="bar-dark">
      <h1 class="title">Artist List</h1>
    </ion-header-bar>
    <div class="bar bar-subheader item-input-inset bar-light">
      <label class="item-input-wrapper">
        <i class="icon ion-search placeholder-icon"></i>
        <input type="search" placeholder="Search">
      </label>
    </div>
    <ion-content ng-controller="ListController" class="has-subheader">
      <ion-list >
        <ion-item ng-repeat='item in artists' class="item-thumbnail-left item-text-wrap">
          <img src="http://placehold.it/100x100" alt="photo">
          <h2>{{item.name}}</h2>
          <h3>{{item.reknown}}</h3>
          <p>{{item.bio}}</p>


       </ion-list>

       </div>
      </ion-content>
    </ion-pane>
  </body>

the app.js file is: app.js 文件是：

angular.module('starter', ['ionic'])

  .run(function($ionicPlatform) {
    $ionicPlatform.ready(function() {
      if(window.cordova && window.cordova.plugins.Keyboard) {
        // Hide the accessory bar by default (remove this to show the accessory bar above the keyboard
        // for form inputs)
        cordova.plugins.Keyboard.hideKeyboardAccessoryBar(true);

        // Don't remove this line unless you know what you are doing. It stops the viewport
        // from snapping when text inputs are focused. Ionic handles this internally for
        // a much nicer keyboard experience.
        cordova.plugins.Keyboard.disableScroll(true);
      }
      if(window.StatusBar) {
        StatusBar.styleDefault();
      }
    });
  })
  .controller('ListController', ['$scope', '$http', function($scope, $http) {
    $http.get('js/data.json').success(function(data){
      $scope.artists = data;
    });
  }]);

Answer 1

You have not closed <ion-item> in your code maybe.您可能没有在代码中关闭<ion-item> 。

<ion-content ng-controller="ListController" class="has-subheader">
   <ion-list >
        <ion-item ng-repeat='item in artists' class="item-thumbnail-left item-text-wrap">
          <img src="http://placehold.it/100x100" alt="photo">
          <h2>{{item.name}}</h2>
          <h3>{{item.reknown}}</h3>
          <p>{{item.bio}}</p>
        </ion-item> <!--   This was missing   -->
   </ion-list>
 </div> <!--   This is extra   -->
</ion-content>

I've created a CodePen of your code and it seems everything is working perferctly.我已经为您的代码创建了一个CodePen ，看起来一切正常。

You could try adding console.log($scope.artists) after receiving the data from $http to ensure your json is received and binded in the scope.您可以尝试在收到来自$http的数据后添加console.log($scope.artists)以确保您的 json 被接收并绑定在范围内。

Hope it helps希望能帮助到你

According to your code, try to use ng-repeat in ion-list根据您的代码，尝试在ion-list使用 ng-repeat

<ion-list ng-repeat='item in artists'>
    <ion-item class="item-thumbnail-left item-text-wrap">
        <img src="http://placehold.it/100x100" alt="photo">
        <h2>{{item.name}}</h2>
        <h3>{{item.reknown}}</h3>
        <p>{{item.bio}}</p>
</ion-list>
