ng repeat为嵌套的ng repeat动态创建数组

这是可能的,而且在我看来这不是一个坏主意,例如,如果您的subRow数据很大或是图像,您可能只想在用户单击displaySubRow项目时加载subRow数据,以避免给服务器带来不必要的负担或让用户等待。

html

<table>
      <tbody ng-repeat="item in data" ng-init="item.show = false">
    <tr>
        <td>
            <button ng-show="item.show==false" ng-click="getRowSubItems(item)">Show</button>
            <button ng-show="item.show==true" ng-click="item.show = false">Hide</button>
        </td>
        <td>
          {{item.name}}
        </td>
