我正在尝试使用 ng-repeat 在 blockquote 中打印来自 dishDetailController 的一组注释。我试过了，但我不知道该怎么做。任何帮助将不胜感激，谢谢。这是代码。

  </div>

您面临的问题是 Controller 在 blockquote 段中无效。

带有 ng-controller="dishDetailController as dish" 的 div 在这个特定的 div 之前被关闭。为了克服这个问题，您可以将段移动到上面的 div。

<div class="row row-content" ng-controller="dishDetailController as dish">
.
.
.
  <blockquote ng-repeat="com in dish.comments">
    <!--In this blockquote. -->
    {{ com.comment }}
    {{ com.rating }}
    {{ com.author }}
  </blockquote>
</div>
