如何在嵌套的 ng-repeat 中访问超级父级的索引 [英] How to access the index of super parent in nested ng-repeats

问题描述

我想访问最外层 ng-repeat 的索引.

<div ng-repeat=""><div ng-repeat="">//我想在这里获取外部ng-repeat的$index

解决方案

使用ng-init设置外层索引:

然后您可以在其他范围内使用 outerIndex.

Angular 文档中专门有这个例子

I want to access the index of the outermost ng-repeat.

<div ng-repeat="">
  <div ng-repeat="">
    <div ng-repeat="">
      //I want to get the $index of outer ng-repeat here
    </div>
  </div>
</div>

解决方案

Use ng-init to set the outer index:

<div ng-repeat="" ng-init="outerIndex = $index">

Then you can use outerIndex in the other scopes.

Angular documentation has this example specifically
