Hi

I need to change the class in the code via onclick, the following is a basic idea of what I need but javascript does not seem to accept .class -- Any help really appreciated!

<SCRIPT>
function ChangeClass() {

var ClassName = document.getElementById("WhatClass")

ClassName.class="NEW_VALUE"

}

</SCRIPT>

<div ID="WhatClass" class="ORIGIONAL_VALUE">

<a onclick="ChangeClass();">TEST</a>

Kind Regards

Walker

It would seem I chose an unfortunate name origionally className appears to be CODE.

THE Following works for anyone who needs it in the future:

<SCRIPT>
function ChangeClass() {

var NAME = document.getElementById("WhatClass")

NAME.className="NEW_VALUE"

}

</SCRIPT>

<div ID="WhatClass" class="ORIGIONAL_VALUE">

<a onclick="ChangeClass();">TEST</a>

Kind Regards

Walker
