Element: getAttributeNode() method

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

js
getAttributeNode(attrName)

Parameters

  • attrName is a string containing the name of the attribute.

Return value

An Attr node for the attribute.

Examples

js
// 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.
