...but not for compliant browsers like FF.
See this code:
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01//EN"
"http://www.w3.org/TR/html4/strict.dtd">
<html>
<head>
<title></title>
<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1">
<style type="text/css">
#nav a {
color:#f00;
text-decoration:none;
}
ul
{
list-style-type:none;
font-family:Tahoma;
font-size:10pt;
}
</style>
<script type="text/javascript">
window.onload=function()
{
var accept=document.getElementById('nav').getElementsByTagName('a');
for(var start=0;start<accept.length;start++)
{
accept[start].onclick=function()
{
for(var start=0;start<accept.length;start++)
{
accept[start].style.textDecoration='none';
{
this.style.textDecoration='underline';
this.style.color='#9900FF';
}
}
}
}
}
</script>
</head>
<body>
<ul id="nav">
<li><a href="#">navigation one</a></li>
<li><a href="#">navigation two</a></li>
<li><a href="#">navigation three</a></li>
<li><a href="#">navigation four</a></li>
<li><a href="#">navigation five</a></li>
</ul>
</body>
</html>
See if it helps ;)
