Question

我有一个使用angularJs制作的移动应用程序并实现了css。

它使用API显示数据并且包含电话间隙。

我正在用这个应用程序解决我的主要问题。如果你们中的任何人帮助我，我会感谢你们。

当我在app中使用此代码时，其负载但未显示在

中

<div class="card" ng-repeat="x in campList">
    <div class="card-image waves-effect waves-block waves-light">
        <img class=" materialboxed" src="my-api-source-link/images/slider/{{x.myphoto}}">
    </div>
</div>

并且有证据表明它在浏览器中加载

此照片＆gt;＆gt;

当我使用时没有实现旋转木马，它的装载和显示。
