我试图在角度函数中运行JavaScript函数,但我面临错误 (曾经索引,搜索功能不起作用)

 <select class="form-control input-sm input_high" name="groupname" id="groupname" ng-model="tech_groupname">
                    <option value="">Select</option>
                    <option value="Dedicated-1">Test1</option>
                    <option value="Dedicated-2">Test2</option>
                    <option value="Yellow-2">Test3</option>
  </select>

<div class="ui-widget" ng-if="checkCorpPackage(tech_groupname)" ></div>

appTechInfo.controller('tech_info_ctrl', ['$scope',function($scope)
  { 
   //** check if package is corporate and need if start
    $scope.checkCorpPackage = function(temp_grp_name){
        //value is printed here if javascript function is not used
        console.log(temp_grp_name);

         //i have tested by getting data via scope too
        var test_data = $scope.tech_groupname;

        console.log(temp_grp_name.toLowerCase());
        /**
        if(temp_grp_name.indexof("Dedicated") > -1)
        {

           return true; 
        }
        else
        {
            return false;
        } 
         **/                  
    }
    //** check if package is corporate and need if start
  }]); 

错误日志 TypeError:无法读取未定义的属性'toLowerCase'

我已经搜索过类似的问题,但他们提供的解决方案对我不起作用

temp_grp_name将是未定义的,因为它的值将在更改选择控件时更改。所以你必须通过检查undefined或null来处理它。 indexof indexOf ,如下所示

temp_grp_name.indexOf("Dedicated")
