Drag & Drop is a common feature that grabs an object and drags it to another location. In HTML5, drag and drop is part of the standard, and any element can be dragged and dropped. In the past, we used the Mousedown, Mouseove, Mouseup and other events of the mouse to constantly acquire the coordinates of the mouse to modify the position of the element. Now the html5 native Drag & Drop event (DnD) is convenient and the performance is improved.
Internet Explorer 9+, Firefox, Opera 12, Chrome, and Safari 5 support drag and drop.
