element.removeAttributeNode

removeAttributeNode removes the specified attribute from the current element.

Syntax

removedAttr = element.removeAttributeNode(attributeNode)
  • attributeNode is the Attr node that needs to be removed.
  • removedAttr is the removed Attr node.

Example

// <div id="top" align="center" />
var d = document.getElementById("top"); 
var d_align = d.getAttributeNode("align"); 
d.removeAttributeNode(d_align); 
// align is now removed: <div id="top" />

Notes

If the removed Attribute has a default value it is immediately replaced. The replacing attribute has the same namespace URI and local name, as well as the original prefix, when applicable.

There is no removeAttributeNodeNS (unlike the pair setAttributeNode andsetAttributeNodeNS which need to know which existing attribute to replace (if any), removeAttributeNode has no such requirement). removeAttributeNode can remove namespaced as well as non-namespaced attributes.

DOM methods dealing with element's attributes:

Not namespace-aware, most commonly used methods Namespace-aware variants (DOM Level 2) DOM Level 1 methods for dealing with Attr nodes directly (seldom used) DOM Level 2 namespace-aware methods for dealing with Attr nodes directly (seldom used)
setAttribute (DOM 1) setAttributeNS setAttributeNode setAttributeNodeNS
getAttribute (DOM 1) getAttributeNS getAttributeNode getAttributeNodeNS
hasAttribute (DOM 2) hasAttributeNS - -
removeAttribute (DOM 1) removeAttributeNS removeAttributeNode -
