如何在父ng-repeat中访问当前的子ng-repeat对象

Question

我正在使用Angular 1.5.8和光滑的滑块1.6.0。在我的项目中，我有一个父母ng-repeat和一个孩子ng-repeat。我的光滑滑块包含一个ng-repeat，它接收来自API数据的图像。我当前的父ng-repeat对象被称为'key'，而我当前的子ng-repeat对象被称为'thumbkey'（在key.allimages中）。我需要将光滑滑块外的当前thumbkey对象进行一些操作。

（如果我可以在'init'或'afterchange'事件的滑块上获得'thumbkey'对象，那么我想更改对象内的某些值会更好。

我正在使用Angular指令进行光滑的“angular-slick-carousel”。
