jQuery/Ajax form validation

Why on earth would you do it that way? That is bad practice, extra work, insecure and would break for anyone without JavaScript!

I consider adding a return false; on fail at the bottom of your jQuery .submit() to be considerably easier, and will allow JS and non-JS users to use the site fully.

You can even use $.post() and return false; so it will submit the form via AJAX or normal HTTP.

The only time I would consider coding the way you suggested is in something like AIR where you KNOW JavaScript is going to be enabled.
