Definition and Usage of HTML ondragstart Event Attribute

The ondragstart attribute fires when the user starts to drag an element or text selection.

Drag and drop is a very common feature in HTML5. It is when you "grab" an object and drag it to a different location. For more information, see our HTML Tutorial on HTML5 Drag and Drop.

Note: To make an element draggable, use the global HTML5 draggable attribute.

Tip: Links and images are draggable by default, and do not need the draggable attribute.

There are many event attributes that are used, and can occur, in the different stages of a drag and drop operation:

• Events fired on the draggable target (the source element):
  • ondragstart - fires when the user starts to drag an element
  • ondrag - fires when an element is being dragged
  • ondragend - fires when the user has finished dragging the element


• Events fired on the drop target:
  • ondragenter - fires when the dragged element enters the drop target
  • ondragover - fires when the dragged element is over the drop target
  • ondragleave - fires when the dragged element leaves the drop target
  • ondrop - fires when the dragged element is dropped on the drop target
