AngularJS ng-options将选定项目作为对象

Question

我的范围内有一个对象数组,我将它们列在下面的下拉控件中.

 <select ng-model="selectedItem" ng-options="product.ID as product.Name for product in products">
     <option value="">Please select a product...</option>
 </select>

我还希望将selectedItem作为对象来获取对象的其他属性,以便我可以在页面中进行内容管理.例如;

<a ng-show="selectedItem.isAvailable">Buy Now!</a>

谁能帮我这个？谢谢.

Answer 1

您只需select as要从ng-options中删除部分,以便所选的product将是ngModel , selectedItem.

尝试:-

 <select ng-model="selectedItem" ng-options="product.Name for product in products track by product.id">
     <option value="">Please select a product...</option>
 </select>

您当前的语法是select as label for value in array哪里select就是product.ID,让你只需将其更改为label for value in array
