javascript - 使用静态值获取 AngularJS 中 ng-change 的下拉值

Question

我想在更改 ng-change 上的下拉菜单时获得值(value)。我的代码如下:-

<select class="form-control" id="cobSRQ2" ng-change="cobchange()" required>
    <option>[Select One]</option>
    <option value="Primary" selected>Primary</option>
    <option value="Secondary">Secondary</option>
    <option value="Tertiary">Tertiary</option>
</select>

我想将值发送到 Angular JS Controller 。

请帮忙

使用 ng-model 传递值:

 app.controller('controllername',function($scope){
 $scope.drpmodel=-1
 $scope.cobchange=function(){

     alert($scope.drpmodel);

  }


 });

 <select class="form-control" id="cobSRQ2" ng-model="drpmodel" ng-change="cobchange()" required>
   <option value="-1">[Select One]</option>
   <option value="Primary" selected>Primary</option>
   <option value="Secondary">Secondary</option>
   <option value="Tertiary">Tertiary</option>
</select>
