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 anAttr node.
This method is useful if you need the attribute'sinstance properties.If you only need the attribute's value, you can use thegetAttribute() method instead.
Syntax
getAttributeNode(attrName)Parameters
attrNameA string containing the name of the attribute.
Return value
AnAttr node for the attribute.
Examples
// html: <div />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.
TheAttr node inherits fromNode, but is not considered a part of the document tree. CommonNode attributes likeparentNode,previousSibling, andnextSibling arenull for anAttr node. You can, however, get the element to which the attribute belongs with theownerElement property.
