DataTransfer.mozSourceNode

Non-standard
This feature is non-standard and is not on a standards track. Do not use it on production sites facing the Web: it will not work for every user. There may also be large incompatibilities between implementations and the behavior may change in the future.

The DataTransfer.mozSourceNode property is used to determine the Node over which the mouse cursor was located when the the drag operation was initiated (for example, when a <button> was clicked). For external drags or if the calling function cannot reach the node, null is returned.

Note: This property is Gecko-specific.

This property is Read only .

Syntax

dataTransfer.mozSourceNode;

Return value

A Node representing node where the drag originated. Returns null for external drags or if the node cannot be accessed.

Example

function dragend_handler(event)
{
  var dragData = event.dataTransfer;
  var node = dragData.mozSourceNode;
  if (node != null)
    console.log("mozSourceNode = " + dragData.mozSourceNode);
  else
    console.log("mozSourceNode is null");
}
