喜欢这个代码将是完美的，只有计数与组和过滤器不完美。任何人都可以提供帮助因此，主要问题是将过滤器放在类别上。

谢谢， Ajai Pandey

Answer 1

您需要将筛选列表的结果存储在别名中：

 <h3>{{ key }} ({{ filteredList.length }})</h3>
 <li ng-repeat="movie in value | filter:title as filteredList">

很好的部分是你可以使用这个变量上面你要过滤的ng-repeat，只要它在你的控制器范围内。

参见 fiddle

Answer 2

尝试以下代码：

<tr ng-repeat="(key, value) in data">
    <td> {{key}} </td> <td> {{ value }} </td>
</tr>

检查this link以获取有关ng-repeat的文档。
