Convert this PHP in to Javascript?

[JAB Creations]

I'm not sure how to do this in Javascript...

if ($HTTP_COOKIE_VARS[bandwidth]=="2") {echo ' <object type="application/x-shockwave-flash" data="jab-creations-registration-lo.swf" id="gallery" width="1" height="1">'."\n"; echo ' <param name="movie" value="jab-creations-registration-lo.swf" />'."\n"; echo ' <param name="loop" value="false" />'."\n"; echo ' </object>';}
elseif ($HTTP_COOKIE_VARS[bandwidth]=="4") {echo ' <object type="application/x-shockwave-flash" data="jab-creations-registration-hi.swf" id="gallery" width="1" height="1">'."\n"; echo ' <param name="movie" value="jab-creations-registration-hi.swf" />'."\n"; echo ' <param name="loop" value="false" />'."\n"; echo ' </object>';}

Well, you may still need javascript to get the PHP variables:

<script type="text/javascript">
<!--
var bandwidth=<?
echo $HTTP_COOKIE_VARS[bandwidth];
?>;
if(bandwidth == 2)
{
document.write(' <object type="application/x-shockwave-flash" data="jab-creations-registration-lo.swf" id="gallery" width="1" height="1">\n <param name="movie" value="jab-creations-registration-lo.swf" />\n <param name="loop" value="false" />\n </object>';
}
else if(bandwidth == 4)
{
document.write(' <object type="application/x-shockwave-flash" data="jab-creations-registration-hi.swf" id="gallery" width="1" height="1">\n <param name="movie" value="jab-creations-registration-hi.swf" />\n <param name="loop" value="false" />\n </object>');
}
//-->
</script>

You can use javascript to read cookies.

function readcookie(name){
dck=unescape(document.cookie);value="";if(dck.indexOf(name)!=-1)value=dck.substring(dck.indexOf(name)+name.length,dck.indexOf(";",dck.indexOf(name)+name.length)!=-1?dck.indexOf(";",dck.indexOf(name)+name.length):dck.length);return value
}
bandwidth = readcookie("bandwidth");
