Skal det gøres med script, kan du gøre sådan:
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"
"
http://www.w3.org/TR/html4/loose.dtd"><html>
<head>
<title>TITLE</title>
<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1">
<script type="text/JavaScript">
var actCell, loc = location.href;
actCell = (loc.indexOf("?c=")!=-1)? loc.split("?")[1].split("=")[1] : false;
function mOver(c) {
if (c.id==actCell) return;
c.style.backgroundColor = "#ff0000";
c.style.color = "#ffffff";
}
function mOut(c) {
if (c.id==actCell) return;
c.style.backgroundColor = "#ffffff";
c.style.color = "#000000";
}
function mClick(c, url) {
location.href = url + "?c=" + c.id;
}
window.onload = function() {
if (actCell) {
document.getElementById(actCell).style.backgroundColor = "#ff0000";
document.getElementById(actCell).style.color = "#ffffff";
}
}
</script>
</head>
<body>
<table cellspacing="0" cellpadding="0" border="0">
<tr>
<td id="c0" style="cursor:pointer;cursor:hand;" onmouseover="mOver(this)"
onmouseout="mOut(this)" onclick="mClick(this, 'side1.html')">bla bla bla</td>
</tr>
<tr>
<td id="c1" style="cursor:pointer;cursor:hand;" onmouseover="mOver(this)"
onmouseout="mOut(this)" onclick="mClick(this, 'side2.html')">bla bla bla</td>
</tr>
<tr>
<td id="c2" style="cursor:pointer;cursor:hand;" onmouseover="mOver(this)"
onmouseout="mOut(this)" onclick="mClick(this, 'side3.html')">bla bla bla</td>
</tr>
</table>
</body>
