javascript - AngularJS ng-repeat 如何获取 item key？

Question

文档:https://code.angularjs.org/1.2.26/docs/api/ng/directive/ngRepeat

The ngRepeat directive instantiates a template once per item from a collection. Each template instance gets its own scope, where the given loop variable is set to the current collection item, and $index is set to the item index or key.

看起来我得到的是索引而不是键。

Controller :

$scope.items = {
  "key1" : "val1",
  "key2" : "val2"
};

查看:

<div class="item" ng-repeat="item in items">{{ $index }} {{item}}</div>

结果:

0 val1
1 val2

我想显示键，在本例中应该是 key1和key2 。有特殊的语法吗？

尝试

<div class="item" ng-repeat="(key, value) in items">{{ $index }} {{key}} {{value}}</div>
