如何將特定值設置爲下拉角度方式？

我有一個簡單的角度下拉像波紋管：如何將特定值設置爲下拉角度方式？

<select class="form-control" ng-model="docPropIdentityModel.OwnerLevel" 
     ng-options="ownerLevel as ownerLevel.LevelName for ownerLevel in ownerLevels track by ownerLevel.OwnerLevelID"> 
     <option value="">--Select--</option> 
</select>

我已經爲OwnerLevelID的值，我想要分配的OwnerLevelID爲下拉&的值表示各LevelName。我可以很容易地通過使用jquery來做到這一點，但要做到這一點的角度。

我試圖指派像波紋管的模型中的價值：

$scope.docPropIdentityModel.OwnerLevel = "123456";

但沒有奏效。如何做到這一點？

'$ scope.docPropIdentityModel.OwnerLevel = {OwnerLevelID：「123456」};' – Satpal

你確定'OwnerLevelID'是'string'而不是'number'？ '$ scope.docPropIdentityModel.OwnerLevel = 123456;' – Kutyel

當您使用track by表達，您需要設置與ngModel相關對象的OwnerLevelID財產。

$scope.docPropIdentityModel.OwnerLevel = { OwnerLevelID : "123456"};
