Class: Validation on General Form Fields

This class can be used to generate Web forms with Javascript based client side validation.

It can generate the HTML tags for starting and ending forms with one or more fields. The supported types of fields are: text, password, checkbox, select and submit.

Additionally it can generate a Javascript function named validate that should be embedded in the form page so it can be called when the form is submitted to validate the form.

If there are any required fields that are not set, the validate function opens an alert window to tell the user which field needs to be set.
