“dataOrder.operative_order_id”和“orderoperatives.id”具有相同的值，我想要的是显示该值的名称。

如果dataOrder.operative_order_id = 2我需要在ng-option中“选中”

    <select class="form-control"
     ng-model="vm.operative_order_id" 
     ng-selected="dataOrder.operative_order_id" <!--The "id" or "operative_order_id" is from a related table -->
     ng-options="orderoperatives.id as orderoperatives.nombre for orderoperatives in dataOperatives"></select>

Answer 1

<select class="form-control"
     ng-model="vm.operative_order_id" >
<option ng-repeat = "item in orderoperatives " value = "{{item .id}}">{{item .nombre}}}</option>
</select>

你能尝试这样：）

Answer 2

您不需要ng-selected

试试这个

<select class="form-control"  ng-model="dataOrder.operative_order_id" 
ng-options="orderoperatives.id as orderoperatives.nombre for 
orderoperatives in dataOperatives"></select>

或试试这个

<select class="form-control"
 ng-model="vm.operative_order_id" 
 ng-selected="dataOrder.operative_order_id" ng-options="orderoperatives.id as orderoperatives.nombre for orderoperatives in dataOperatives"></select>

您应该在控制器中将dataOrder.operative_order_id分配给vm.operative_order_id，例如

$scope.operative_order_id=$scope.dataOrder.operative_order_id;

ng从显示的表中选择显示值
