HTML ondrop Attribute - HTML Attribute

Definition and Usage

The ondrop attribute fires when a draggable element or text selection is dropped on a valid drop target.

To learn about Drag and Drop, read our HTML Tutorial on HTML5 Drag and Drop.

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
