从AngularJS ng-options中的两个字段构建Select Options

Question

在Angular中，我希望select中显示的内容是数组中对象的两个属性的组合。例如，我在物品上有auctionName和auctionLocation，我希望显示中的文本显示为auctionLocation-auctionName。

<select  ng-model="selectedAuction" ng-options="item.auctionLocation as item.auctionLocation for item in auctions">
              <option value="" disabled selected>All Auctions</option>
  </select>

Answer 1

值可以在ng-options内部连接。

您可以使用:

ng-options="item.auctionLocation as item.auctionName+'-'+item.auctionLocation for item in auctions"
