[edit] Summary

removeAttributeNode removes the specified attribute from the current element.

[edit] Syntax

removedAttr = element.removeAttributeNode(attributeNode)

• attributeNode is the Attr node that needs to be removed.
• removedAttr is the removed Attr node.

[edit] Example

// <div id="top" align="center" />
var d = document.getElementById("top"); 
var d_align = d.getAttributeNode("align"); 
d.removeAttributeNode(d_align); 
// align has a default value, center, 
// so the removed attribute is immediately 
// replaced: <div id="top" align="center" />

[edit] 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.
