By default, data/elements cannot be dropped in other elements. The ondragover event specifies where the dragged data can be dropped.

The event listener ondragstart will set the allowed effects (copy, move, link, or some combination).Įv.tData("text", ev.target.id).The tData() method sets the data type and the value of the dragged data The ondragstart attribute calls a function, drag(event), that specifies what data to be dragged. Then, specify what should happen when the element is dragged.First set the draggable attribute to true for that element to be draggable.The effect can take on one of the following values: none, copy, link, move.
