This event is cancelable and may bubble up to the Document and Window objects.

DragEvent.dataTransferRead only- 
    
The data that is transferred during a drag-and-drop interaction.
 
Examples
Resetting opacity on dragend
In this example, we have a draggable element inside a container. Try grabbing the element, dragging it, and then releasing it.
We make the element half-transparent while it is dragged, and listen for the dragend event to reset the element's opacity when it is released.
For a complete example of drag and drop, see the page for the drag event.
HTML
<div id="container">
  <div id="draggable" draggable="true">This div is draggable</div>

  /* Prevent the user from selecting text in the example */
  user-select: none;

  width: 200px;
  height: 20px;
  background: blueviolet;
  padding: 10px;
}
.dragging {
  opacity: 0.5;

source.addEventListener("dragstart", (event) => {
  // make it half transparent
