hmmm ... that's another question ... try a regExp like the following: - var url = 'http://bytes.com/forum/newthread.php';
-
-
function get_hostname_from_url(url) {
-
return url.match(/:\/\/(.[^/]+)/)[1];
-
}
-
-
alert(get_hostname_from_url(url));
kind regards

looks a little fragile.
try url.split(/\/+/g)[1];
