JavaScript Regex Generator (beta)

First attempt at making a user-friendly regex generator. A little buggy in IE. Currently limited to 7 groups and no support for negating character classes.

This script runs on top of JDC 1.0.3 in Internet Explorer which is why it is executed slightly faster in Firefox, Opera and Safari.
