setAttributeNodeNS
adds a new namespaced attribute node to an element.
Element.setAttributeNodeNS()
Syntax
setAttributeNodeNS(attributeNode)
Parameters
-
attributeNode
is anAttr
node.
Return value
The replaced attribute node, if any, returned by this function.
Examples
// <div id="one" xmlns:myNS="http://www.mozilla.org/ns/specialspace" // myNS:special-align="utterleft">one</div> // <div id="two">two</div> var myns = "http://www.mozilla.org/ns/specialspace"; var d1 = document.getElementById("one"); var d2 = document.getElementById("two"); var a = d1.getAttributeNodeNS(myns, "special-align"); d2.setAttributeNodeNS(a.cloneNode(true)); alert(d2.attributes[1].value) // returns: `utterleft'
Notes
If the specified attribute already exists on the element, then that attribute is replaced with the new one and the replaced one is returned.
Note that if you try to set without cloning the node, Mozilla gives an NS_ERROR_DOM_INUSE_ATTRIBUTE_ERR "Attribute already in use" error, as the DOM requires cloning for Attr to be reused (unlike other Nodes which can be moved).

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) |
