This weekend I spent some time looking at adding support for regular expressions as part of the Google Forms validation functionality.  This seemed like a reasonable and useful request.  I was surprised to find that the jQuery Validation plugin doesn’t offer regular expressions as a standard check  however, I found a fairly simple solution on Stack Exchange.
It took me a little while to get it working as Saturday morning I went down a wrong path initially following another post I had found.  When I first read the post I linked to above, I convinced myself that I didn’t want to use the AddMethod solution.  I am not sure why, I guess it was because I haven’t been into the code in a while so I was trying to avoid it.  It turns out it is definitely the right answer and fairly easy to implement.
The beta build also contains a Serbo Croation translation provided by Borisa Djuraskovic

To see the new functionality in action, check out my Validation Demo Form where the last entry field must begin with a capital letter.  The regular expression “[A-Z]” is used to match a capital letter when setting up the validation.
