Returns the specified attribute of the specified element, as an Attr
node.
Syntax
var attrNode = element.getAttributeNode(attrName);
attrNode
is anAttr
node for the attribute.attrName
is a string containing the name of the attribute.
Example
// 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.
getAttribute is usually used instead of getAttributeNode
to get the value of an element's attribute.
