form-validation

I'm already familiar with how to use onSubmit to evaluate form content against RegEx to ensure it meets static parameters for acceptable content. What I'm wondering is if there is a way to further provide validation against a MySQL database, such as if you want to make sure an e-mail address hasn't been used yet before submitting a form and having to re-load the field data back into the proper places for correction.
