javascript - 无法弄清楚为什么 ng-repeat 不排序

Question

我有以下 HTML，我想按最新的评论按时间倒序排序:

<div class="list list-inset"
    ng-repeat="(threadId, thread) in messageThreads | orderBy:'thread.newestComment'"
    ng-if="thread.newestComment > messageClearTime">
    <div class="item item-divider">
        {{thread.newestComment}}
    </div>
</div>

数据(messageThreads)是这样的，以threadId为键，newestComment为时间戳:

{ "5381897" : {
      "newestComment" : 1403280014,
      "title" : "asdf"
    },
  "5595015" : {
      "newestComment" : 1403192555,
      "title" : ""
    },
  "5761260" : {
      "newestComment" : 1403126044,
      "title" : ""
    },
  "5838498" : {
      "newestComment" : 1403279962,
      "title" : "Share Test"
    }
}

无论我做什么，我似乎都无法弄清楚如何对其进行排序——它总是按照数组的顺序出现。有什么帮助吗？

orderBy 过滤器仅适用于对象数组，不适用于对象本身。请参阅文档 here .
