我不确定为什么会收到此错误,有人可以向我解释一下吗?

我创建了一项服务,以便存储,更新和返回零件清单的值。我在点击不同的单选按钮后尝试更新partsList。
此外,如果您知道如何通过不同的视图更改来保持这些选择,这些更改也很棒。
谢谢!
这是我的服务代码:
mainApp.controller('controller_Computer_Type', ['$scope', function ($scope, MyService) {
//Computer Type Selected
$scope.current = MyService.getValueByName("selected_computer_type");
//Updates the partsList
$scope.change = function () {
var value = $scope.current.toString();
MyService.setValue("selected_computer_type", value);
};
//List of options for computer type
$scope.types = [
//TODO: update url images to reflect personal gaming and business profiles
{name: 'Personal', value: 'personal', url: 'images/intel 700/ABFS_1_201706141903610053.jpg'},
{name: 'Gaming', value: 'gaming', url: 'images/amd 500/83-230-100-02.jpg'},
{name: 'Business', value: 'business', url: 'images/intel 500/83-101-369-z01.jpg'}
];
}]);
这是我的控制器代码:
<div ng-controller="controller_Computer_Type">
<h2>Type of Computer</h2>
<!--Radio Button Options Using Images-->
<div class="row">
<label class="col-sm-4" ng-repeat="option in types">
<input type="radio" name="radio_type" ng-model="$parent.current" ng-change="change()" value="{{option.value}}" hidden/>
<img class="img-thumbnail" src="{{option.url}}" alt="{{option.value}}">
<img class="overlay" src="images/greenCheck.png">
</label>
</div>
<!--Debugging purposes-->
<p>Current RB - {{current}}</p>
<p>Current DD - {{selectedItem.name}}</p>
<p>Message - {{message}}</p>
</div>
这是我的观看代码:
