laravel中的select控件选项中的ng-value，未获得与ng-value相同的value参数

Question

Laravel视图文件中的代码：

<select class="form-control" ng-model="voucher.card_type" > <option value="">Choose Card Type</option> <option ng-repeat="cardList in cardTypes" ng-value="@{{cardList.id}}"> @{{cardList.card_type}} </option> </select>

预期的html标签：

<select class="form-control ng-pristine ng-valid ng-empty ng-touched" ng-model="voucher.card_type">
      <option value="">Choose Card Type</option>
      <!-- ngRepeat: cardList in cardTypes --><option ng-repeat="cardList in cardTypes" ng-value="57" class="ng-binding ng-scope" value="57">ChristmasCard</option><!-- end ngRepeat: cardList in cardTypes -->
      <option ng-repeat="cardList in cardTypes" ng-value="58" class="ng-binding ng-scope" value="58">AnniversaryCard</option>
      <!-- end ngRepeat: cardList in cardTypes -->

但是它让我得到了名称而不是与ng-value相同的id的value参数。

HTML标记已创建：

<select class="form-control ng-pristine ng-valid ng-empty ng-touched" ng-model="voucher.card_type">
      <option value="">Choose Card Type</option>
      <!-- ngRepeat: cardList in cardTypes --><option ng-repeat="cardList in cardTypes" ng-value="57" class="ng-binding ng-scope" value="ChristmasCard">ChristmasCard</option><!-- end ngRepeat: cardList in cardTypes -->
      <option ng-repeat="cardList in cardTypes" ng-value="58" class="ng-binding ng-scope" value="AnniversaryCard">AnniversaryCard</option>
      <!-- end ngRepeat: cardList in cardTypes -->

我没有在选项中提供value参数，它一直工作到2018年10月结束，并在value中获取id，突然之间，值获取的是名称而不是id。

有帮助吗？ 我的angular js版本是1.5.5
