javascript - 从子ng-repeat访问父ng-repeat的索引(Access index of the parent ng-repeat from child ng-repeat)

Question

I want to use the index of the parent list (foos) as an argument to a function call in the child list (foos.bars).(我想使用父列表的索引（foos）作为子列表（foos.bars）中函数调用的参数。)

I found a post where someone recommends using $parent.$index, but $index is not a property of $parent .(我找到了一个帖子，有人建议使用$ parent。$ index，但$index不是$parent的属性。)

How can I access the index of the parent ng-repeat ?(如何访问父ng-repeat的索引？)

<div ng-repeat="f in foos">
  <div>
    <div ng-repeat="b in foos.bars">
      <a ng-click="addSomething($parent.$index)">Add Something</a>
    </div>
  </div>
</div>

Answer 1

My example code was correct and the issue was something else in my actual code.(我的示例代码是正确的，问题是我的实际代码中的其他问题。)

Still, I know it was difficult to find examples of this so I'm answering it in case someone else is looking.(尽管如此，我知道很难找到这样的例子所以我正在回答它，以防其他人在寻找。)

<div ng-repeat="f in foos">
  <div>
    <div ng-repeat="b in foos.bars">
      <a ng-click="addSomething($parent.$index)">Add Something</a>
    </div>
  </div>
</div>
