If you're like me, you've pressed the submit on a form and then realized a minute later that the computer hadn't picked it up. Or you didn't think you fully pressed the submit button to e-mail someone, only to figure out that your recipient received two or three multiple requests from you. Well, no more of those worries with the Submit Disabler. Now your visitors can be sure they pressed the submit button and you won't be bothered with multiple forms. I highly recommend this script and I personally will be sure to use it whenever I put a new form on my page.
Color coding is provided, but the script is easy enough to customize without it.
