如何为以下Json数据编写重复？

Question

我的数据如下所示。我尝试过键，但它不起作用。 我想在下拉列表中使用ng-repeat显示所有Product_Groups。 我正在使用

ng-repeat="value.Product_Group for (key, value) in pgroup track by $index"

Answer 1

试试这个

  <div ng-repeat="item in pgroup track by $index">
    {{item.Product_Group}}
  </div>

而不是

ng-repeat="value.Product_Group for (key, value) in pgroup track by $index"

var myApp = angular.module('myApp',[]);

myApp.controller('MyCtrl', function($scope) {
    $scope.pgroup = [
     {Product_Group: "TrueBeam"},
     {Product_Group: "TrueBeam1"},
     {Product_Group: "TrueBeam2"}
    ];
});

<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>
<div ng-app="myApp" ng-controller="MyCtrl">
  <div ng-repeat="item in pgroup track by $index">
    {{item.Product_Group}}
  </div>
</div>
