{{APIRef("HTML Drag and Drop API")}}

The DragEvent interface is a DOM event that represents a drag and drop interaction. The user initiates a drag by placing a pointer device (such as a mouse) on the touch surface and then dragging the pointer to a new location (such as another DOM element). Applications are free to interpret a drag and drop interaction in an application-specific way.

This interface inherits properties from {{domxref("MouseEvent")}} and {{domxref("Event")}}.

Instance properties

  • {{domxref('DragEvent.dataTransfer')}} {{ReadOnlyInline}}
    • : The data that is transferred during a drag and drop interaction.

Constructors

Although this interface has a constructor, it is not possible to create a useful DataTransfer object from script, since {{domxref("DataTransfer")}} objects have a processing and security model that is coordinated by the browser during drag-and-drops.

  • {{domxref("DragEvent.DragEvent", "DragEvent()")}}
    • : Creates a synthetic and untrusted DragEvent.

Event types

  • {{domxref("HTMLElement/drag_event", "drag")}}
    • : This event is fired when an element or text selection is being dragged.
  • {{domxref("HTMLElement/dragend_event", "dragend")}}
    • : This event is fired when a drag operation is being ended (by releasing a mouse button or hitting the escape key).
  • {{domxref("HTMLElement/dragenter_event", "dragenter")}}
    • : This event is fired when a dragged element or text selection enters a valid drop target.
  • {{domxref("HTMLElement/dragleave_event", "dragleave")}}
    • : This event is fired when a dragged element or text selection leaves a valid drop target.
  • {{domxref("HTMLElement/dragover_event", "dragover")}}
    • : This event is fired continuously when an element or text selection is being dragged and the mouse pointer is over a valid drop target (every 50 ms WHEN mouse is not moving ELSE much faster between 5 ms (slow movement) and 1ms (fast movement) approximately. This firing pattern is different than {{domxref("Element/mouseover_event", "mouseover")}} ).
  • {{domxref("HTMLElement/dragstart_event", "dragstart")}}
    • : This event is fired when the user starts dragging an element or text selection.
  • {{domxref("HTMLElement/drop_event", "drop")}}
    • : This event is fired when an element or text selection is dropped on a valid drop target.
