The Node.getUserData() method returns any user DOMUserData set previously on the given node by Node.setUserData().

userData = someNode.getUserData(userKey);

Parameters

  • userKey is the key to choose the specific data sought for the given node. More than one key may have been assigned on a given node, containing its own value.

Example

var d = document.setUserData('key', 15, null);
