Question

我正在按照此链接中的ng-repeat说明进行操作

Angular ng-repeat Error "Duplicates in a repeater are not allowed."

但在我的情况下，我在我的组合框中使用ng-repeat

这是我的视图代码（超薄格式）

md-input-container flex="50"
  label Period
  md-select name="type" ng-model="period"
    md-option ng-repeat=" period in periods track by $index" value="{{period.value}} track by $index"
      | {{period.name}}

这是我的控制器（咖啡脚本格式）

  $scope.periods = [{ "id": 1 ,"value": 1.0 , "name": "amtopm" }, { "id": 2 , "value": 0.5 , "name": "amtoam" }, { "id": 3 , "value": 0.5 , "name": "pmtopm" }]

这可以解决吗？

我的错误

错误：select中不允许重复的md-option值。找到重复值“0.5 track by $ index”
