AngularJS 在 select 菜单中显示多个值？

Question

我有一个 select 菜单使用 Angular 1.5.11:

 <select ng-model="abc.user.state" name="state" ng-options="option.code as option.name for option in abc.brStateSelect.options | orderBy: 'name' track by option.code"
    class="form-control" required></select>

使用json如

[{ "id": 11, "name": "Rondônia", "code": "RO" }, { "id": 12, "name": "Acre", "code": "AC" }]

并且菜单正确显示 "name" 道具。但是我想显示两个道具："name" 和 "code" 例如 Acre - AC 作为菜单项。

如何修改我的 ng-options 以将多个字段显示为标签？

Answer 1

你可以做到，

<select ng-model="abc.user.state" name="state" ng-options="option.name  as option.name + '-' + option.code  for option in datas | orderBy: 'name' track by option.code"  class="form-control" required></select>

演示

var app = angular.module("myApp", []);
app.controller("myCtrl", function($scope) {
$scope.datas =
  [{ "id": 11, "name": "Rondônia", "code": "RO" }, { "id": 12, "name": "Acre", "code": "AC" }];
});
