Simple cut-and-paste boilerplate script solves a common problem with bad e-mail address entries on forms. The script checks e-mail addresses for all common entry errors using powerful regular expressions. This short, easy, reliable script double-validate e-mail addresses with entry and confirm-entry boxes. Can be used to then refer to a subsequent page or call a Perl script, etc.

Got a submissions form that you keep getting multiple submissions from? I've found that in most cases its because people are impatient and click the submit button repeatedly until they get a response. The unfortunate result is that you receive multiple copies of the same form. This little bit of JavaScript disables the submit button as soon as it is clicked for the first time and prevents the user sending their form multiple times. Script now also changes the text on the button to 'Thanks' (this can be modified to suit)

This simple cut-and-paste script opens the Print Dialogue, and lets your visitor print out the current page. Useful for information pages, script pages, receipt pages, etc.
