已废弃
This feature is obsolete. Although it may still work in some browsers, its use is discouraged since it could be removed at any time. Try to avoid using it.
The Node.getUserData() method returns any user DOMUserData set previously on the given node by Node.setUserData().
The Node.setUserData and Node.getUserData methods are no longer available from Web content. Element.dataset or WeakMap can be used instead.
Syntax
userData = someNode.getUserData(userKey);
Parameters
userKeyis 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);
alert(document.getUserData('key')); // 15
