Node.getUserData()
Obsolete
This feature is obsolete.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
JavaScript
Copy Code
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
JavaScript
Copy Code
var d = document.setUserData('key', 15, null); console.log(document.getUserData('key')); // 15
