AngularJS - ng-repeat array with string index

Question

如何 ng-repeat 带字符串索引的数组？请参阅下面的代码片段 -

下面的代码在控制器中。

 $scope.days = ["mon", "tue", "wed" .... "sun"];
$scope.arr = [];
$scope.arr["mon"] = ["apple","orange"];
$scope.arr["tue"] = ["blue","swish"];
.
.
.
$scope.arr["sun"] = ["pineapple","myfruit","carrot"];

问题 - 如何 ng-repeat 像下面的东西，这可能吗？

 <div ng-repeat="day in days">{{day}}
    <span ng-repeat="item in arr(day)">{{item}}</span>
    <-- Something like "arr(day)", can it be done in angular -->
</div>

您可以只对数组中的项目使用普通语法。请参考我的小提琴

<div ng-app='app' ng-controller='default' ng-init='init()'>
  <div ng-repeat='day in days'>
    <strong>{{day}}</strong><br/>
    <span ng-repeat="item in arr[day]">{{item}} </span>
  </div>
</div>
