如何在下拉列表中仅存储 ID Bootstrap

Question

<div class="form-group">                           
    <label for="title" class="col-sm-2 control-label">Section Id</label>
    <div class="col-sm-10">
        <select ng-model="product.sectionId" class="form-control" ng-options="section.name for section in sections track by section.id">
        </select>
    </div>
</div>

这是我的代码，我通过 JSON 和 section has id,name 填充 sections 对象。我只想在我的 product.sectionId 中存储 section.id 但它存储了部分 ID 和名称，如下所示 "sectionId":{"id":"Iron Man","name":"Superman"}。我只想存储 id。有没有办法做到这一点。我是 bootstrap 和 angularjs 的新手，请帮助我。谢谢

Answer 1

将您的 ng-option 更改为

标记

ng-options="section.id as section.name for section in sections"

这将 section.name 和 select section.id 当您 select 任何选项时。

Do not use select as and track by in the same expression. They are not designed to work together.
