Definition and Usage
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):
- 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
