This is a very easy-to-setup form validation script. The main idea is: we heed to write NOTHING of JavaScript to handle whole form validation process. This script allows you to specify certain form elements as "required" or "non-required" and also what specific type they have: text, password, numeric, zip code etc. The script checks automatically all required elements to make sure that they are NOT only empty before allowing the form submission, but also that the surfer entered a valid type value.
