您可以使用$element。演示链接

JS代码：

<script>

demoApp = angular.module('demoApp',[]);

demoApp.controller('testCntr', function ($scope,$element) 
  {
  $scope.test = function()
    {

      var result = document.getElementsByClassName("multi-files");
     // alert(this.className);
      console.log($scope);
 console.log($element.className);



    }

});
</script>
