Element: getAttributeNode() method
Baseline Widely available
This feature is well established and works across many devices and browser versions. It’s been available across browsers since July 2015.
Returns the specified attribute of the specified element, as an Attr
node.
This method is useful if you need the attribute's instance properties.
If you only need the attribute's value, you can use the getAttribute()
method instead.
Syntax
getAttributeNode(attrName)
Parameters
attrName
-
A string containing the name of the attribute.
Return value
An Attr
node for the attribute.
Examples
// html: <div id="top" />
let t = document.getElementById("top");
let idAttr = t.getAttributeNode("id");
alert(idAttr.value === "top");
Notes
When called on an HTML element in a DOM flagged as an HTML document, getAttributeNode
lower-cases its argument before proceeding.
The Attr
node inherits from Node
, but is not considered a part of the document tree. Common Node
attributes like parentNode, previousSibling, and nextSibling are null
for an Attr
node. You can, however, get the element to which the attribute belongs with the ownerElement
property.
