使用select2（）显示选择下拉选项（）

Question

我有两个下拉选择框，我使用AngularJS在下拉菜单中显示选项。

在我的脚本中，当我使用$(".select2_demo_1").select2();时，只有一个下拉菜单一次显示选定的选项。我想显示两个下拉菜单以显示选定的选项。请帮助。

<select id="one" class="select2_demo_1 form-control" ng-model="orgs" ng-options="item.OrganizationTypeTitle for item in organization"></select> 
<select id="two" class="select2_demo_1 form-control" ng-model="industry" ng-options="i.IndustryTypeTitle for i in industries"></select> 

var getOrganizationTypes = OrgService.getOrganizationTypes(); 

getOrganizationTypes.then(function (response) { 
    $scope.organization = response.data; 
    $scope.orgs = $scope.organization[0]; 

}, function() { 
    alert('can not get Organization Types!'); 
}); 

var getIndustryTypes = OrgService.getIndustryTypes(); 

getIndustryTypes.then(function (response) { 

    $scope.industries = response.data; 
    $scope.industry = $scope.industries[0]; 

}, function() { 

    alert('can not get industry types'); 

})

你需要一个循环从相同的CSS中获得价值

 $(function() { 
     var v = []; 
     $(".select2_demo_1").each(function(){ 
      v.push($(this).val()); 
     }) 
     });

     <select class="select2_demo_1" name="drp_Books_Ill_Illustrations" > 
      <option value="1">1</option> 
      <option value="2" selected>2</option> 
      <option value="3">3</option> 
      <option value="4">4</option> 
     </select> 


<button class="getValue">Get Value</button> 
<button class="setValue"> Set value </button> 



$(".getValue").click(function() { 
      var v = []; 
     $(".select2_demo_1").each(function(){  
      v.push($(this).val()); 
      alert($(this).val()) 
     }) 
    });
