HTML != Javascript. Javascript is completely literal, %20 is %20 and is a string of characters & n b s p and ;. For character classes I consider nearly every that is RegEx in perl to be applicable in JS (you can't do named groups etc).
http://www.regular-expressions.info/javascript.html is the refernece I use.
