ng-repeat, $index and offset problems?

<ul class="stream-informer-short-list">
  <li class="stream-informer-short-list-item" ng-repeat="streamer in streamerItems">
     <a href="stream.html"><img src="{{streamer.imageUrl}}"></a>
  </li>
</ul>

我如何使用$index偏移前X项?{{流光。imageUrl[$index+4}} -工作不正确。或者我必须为这个动作写过滤器?

ng-switch可以与$index一起使用，以允许ng-repeat项具有不同的HTML:

<ul class="stream-informer-short-list">
  <li class="stream-informer-short-list-item" ng-repeat="streamer in streamerItems">
     <span ng-switch on="$index <= 4">
       <a ng-switch-when="true" href="stream.html">
          <img src="{{streamer.imageUrl[$index+4]}}"></a>
       <a ng-switch-default href="stream.html">
          <img src="{{streamer.imageUrl[$index]}}"></a>
     </span>
  </li>
</ul>
