DragEvent()
This constructor is used to create a synthetic DragEvent object.
Although this interface has a constructor, it is not possible to create a useful DataTransfer object from script, since DataTransfer objects have a processing and security model that is coordinated by the browser during drag-and-drops.
该接口继承了 MouseEvent 和 Event 的属性。
