removeAttributeNode removes the specified attribute from the current element.
Syntax
removedAttr = element.removeAttributeNode(attributeNode)
attributeNodeis theAttrnode that needs to be removed.removedAttris the removedAttrnode.
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 and setAttributeNodeNS 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.
