JavaScript HTML Form validation description

A generic function written in JavaScript for validating HTML forms. The script supports all the elements types possible in a form. You set a field to required simply by adding the class req to the elements class attribute. You can specify whether the script should use DOM messages, modal JavaScript dialogues or simple styling of input elements for alerting the user of error. The script also incorporates a conditional requirements feature which allows you to make an elements requirement status depending on another elements value.
