控制器非常简单:

angular.module('redditdupe').controller('frontPage', ['$scope', '$http', '$routeParams',
function frontPage($scope, $http){

$http({
  method: 'GET',
  url: 'https://www.reddit.com/.json'
})
.
then(
        function successCallback(response) 
        {          
            $scope.children=response.data.data.children;
        }
        , 
        function errorCallback(response) {

        }
    );

}]);
html也是如此:

<div class="cartouche" ng-repeat="child in children">
    <div ng-repeat="data in child">             
        <img src="{{ data.thumbnail }}"><br> 
        <a href="{{ data.url }}">{{ data.title }}</a> ({{ data.domain }})<br>              
        {{ data.created_utc * 1000 | date:'yyyy-MM-dd HH:mm:ss Z' }} <a href="https://www.reddit.com/user/{{data.author}}">{{data.author}}</a>  <a href="#/{{ data.subreddit_name_prefixed }}">{{ data.subreddit_name_prefixed }}</a><br>
        <a href="#/com/{{ data.subreddit_name_prefixed }}/comments/{{ data.id }}/.json">{{ data.num_comments }}</a><br>
    </div>
</div> 


({data.domain}})
{{data.created_utc*1000}日期:'yyyy-MM-dd HH:MM:ss Z'}

然而,ng重复显示

  • 一组空白结果,后跟
  • 一组真实的结果
  • 然后是另一个空白集
  • 接着是另一个实数集
  • 。。。等等
像这样:

  <--- blank line
()  <--- probably the domain gfycat.com, except it's blank
null < --- dunno
    <--- probably the comment count, but is blank line

您正在迭代子对象的所有值(种类、数据)。为什么要这样做而不是仅仅显示数据?我的理解是,我需要这样做,因为json是对象中重复嵌套的对象结构。每个文章都是一个节点,存储在“所有文章”节点中。因此,我需要循环遍历“所有文章”,并在一个边框内显示“每个文章”。您希望遍历子数组的所有元素。如果此数组的每个元素是一个具有两个属性的对象:种类和数据。所以你的外部ng重复是必要的(child中的child),正如我刚才所说的,child是一个具有两个属性的对象,种类和数据。没有理由让你的内心感到不安——重复一遍。你只想显示child.data.url、child.data.thumbnail等等。你是男人中的上帝。我非常感激。你也许帮我找到了理想的工作。标记为已接受。再次感谢。
