怎么实现ng-repeat的嵌套

Answer 1

<div ng-repeat="links in slides">
<div ng-repeat="link in links track by $index">{{link.name}}</div>
</div>

Error: [ngRepeat:dupes]这个出错提示具体到题主的情况，意思是指数组中有2个以上的相同数字。ngRepeat不允许collection中存在两个相同Id的对象
For example: item in items is equivalent to item in items track by $id(item). This implies that the DOM elements will be associated by item identity in the array.
对于数字对象来说，它的id就是它自身的值，因此，数组中是不允许存在两个相同的数字的。为了规避这个错误，需要定义自己的track by表达式。例如：item in items track by item.id或者item in items track by fnCustomId(item)。嫌麻烦的话，直接拿循环的索引变量$index来用item in items track by $index
