HTML event attribute ondragleave
The ondragleave attribute event is triggered
when a draggable element or text selection leaves a drop target.
To make an element draggable, mark that element
with the global HTML5 draggable attribute.
Links and images are draggable by default.
Events fired on the draggable source element:
- ondragstart - starting dragging
- ondrag - during the dragging
- ondragend - finish dragging
Events fired on the drop target:
- ondragenter - when the dragged element enters the droppable target
- ondragover - when the dragged element is over the droppable target
- ondragleave - when the dragged element leaves the droppable target
- ondrop - when the dragged element is dropped on the droppable target
