我是 Angular 和 ionic 方面的新手，一直在关注教程。我尝试了示例代码，该代码在教程中运行良好，但不适用于我。问题出在 ng-repeat 指令上。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>
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;
});
}]);
data.json 文件是:

最佳答案
您尚未关闭<ion-item>也许在你的代码中。
<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>
我创建了一个 CodePen您的代码似乎一切正常。
您可以尝试添加 console.log($scope.artists)收到$http的数据后确保您的 json 被接收并绑定(bind)在范围内。
希望对你有帮助
关于javascript - 我不知道为什么 ng-repeat 在我的代码中不起作用，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/36226611/
