Summary
setAttributeNode()
adds a new Attr
node to the specified element.
Syntax
replacedAttr =element.setAttributeNode(attribute)
attribute
is theAttr
node to set on the element.replacedAttr
is the replaced attribute node, if any, returned by this function.
Example
// <div id="one" align="left">one</div> // <div id="two">two</div> var d1 = document.getElementById("one"); var d2 = document.getElementById("two"); var a = d1.getAttributeNode("align"); d2.setAttributeNode(a); alert(d2.attributes[1].value) // returns: `left'
Notes
If the attribute named already exists on the element, that attribute is replaced with the new one and the replaced one is returned.
This method is seldom used, with setAttribute()
usually being used to change element's attributes.
