Web/API/Node/getUserData

ObsoleteThis feature is obsolete.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

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);
console.log(document.getUserData('key')); // 15
