AngularJs在ng-click函數中如何獲取代表當前元素的DOM對象

<input class="unchecked" type="checkbox" ng-model="item.isCustOmized" ng-click="switchCheckBox($event, item.isCustOmized)" />

 

$scope.switchCheckBox = function($event, value) {
      // console.log(value)
      if (value) {
        $($event.target).addClass("checked");
      } else {
        $($event.target).removeClass("checked");
      }
    }
