HTML ondragover Attribute


Definition and Usage

The ondragover attribute fires when a draggable element or text selection is being dragged over a valid drop target.

By default, data/elements cannot be dropped in other elements. To allow a drop, we must prevent the default handling of the element. This is done by calling the event.preventDefault() method for the ondragover attribute.

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

Note: While dragging an element, the ondragover event fires every 350 milliseconds.
