角度ng-options，具有按对象id预选的值

Question

以下select是否可以拥有pre-selected分会？

<select ng-model="c.pilot.clubIdx" ng-options="club.idx as club.name for club in c.clubs track by club.idx">

c.pilot.clubIdx = 2
c.clubs = {{idx：1，name：“club1”}，{idx：2，name：“club2”}}

选择菜单应显示“club2”。

由于俱乐部存储在数据库中并且可以更改，我希望将它们仅references保留为pilots。

已解决：通过解决问题来删除曲目。

Answer 1

<select ng-model="c.pilot.clubIdx" ng-options="club.idx as club.name for club   in c.clubs track by club.idx" ng-selected="(club.idx == 2)?true:false">

像这样添加ng-selected。应该预先选择

Answer 2

使用下划线/ lodash在控制器中使用以下行：

var club =_.where(c.clubs, {name:"club2"});
$scope.c.pilot.clubIdx = club.idx;

Answer 3

在控制器中将select的ng-model设置为您想要选择的选项的值。例如：$scope.c.pilot.clubIdx = 2或$scope.c.pilot.clubIdx = $scope.c.clubs[1].idx

Answer 4

removing the track by clause solves the problem. i dont fully understand why, but who knows. angular doc for ngOptions
