URL Validation in JavaScript

This won’t catch every malformed URL, but it’s a pretty good filter:

function test_url(url) {
  // comments:  (protocol )(user&pass   ) (subdomains&domain) (TLD            )(port   ) (path & query string   )
  var regex = /^https?:\/\/(\w+(:\w+)?\@)?([\w\-]+|\.[\w\-]+)+(\.[a-zA-Z]{2,6})(:[0-9]+)?(\/[\w#!:.?+=&%@!\-\/]*)?$/i;
  return url.match(regex);
}

I bet you didn’t think e-mail address validation could be that “easy”. Take a look at http://www.linuxjournal.com/article/9585 (the PHP way). I’m wondering if I should change my e-mail address to {^c\@talin*ciocov^}@somedomain.com .
