---

setAttributeNode adds a new attribute node to the current element.

Syntax

replaced_attr = element.setAttributeNode(attribute)
 

Parameters

attribute is a node of type Attribute

replaced_attr is the replaced attribute node, if any, returned by this function

Example

// <div id="one" align="left">one</div> // <div id="two">two</div> d1 = document.getElementById("one"); d2 = document.getElementById("two"); a = d1.getAttributeNode("align"); d2.setAttributeNode(a); alert(d2.attributes[1].value) // returns: `left'

Notes

If the attribute named already exists on the element, then that attribute is replaced with the new one and the replaced one is returned.
