      //通过controller来获取Angular应用
      var appElement = document.querySelector('[ng-controller=myController]');
      //获取$scope变量
      var $scope = angular.element(appElement).scope();
      //调用msg变量，并改变msg的值
      $scope.msg = '123456';
      //上一行改变了msg的值，如果想同步到Angular控制器中，则需要调用$apply()方法即可
      $scope.$apply();
      //调用控制器中的getData()方法
      console.log($scope.getData());
    }
  }
