Prototype provides an easy way to manage HTML forms. Prototype”s Form is a namespace and a module for all things form-related, packed with form manipulation and serialization goodness.
While it holds methods dealing with forms as a whole, its sub module Form.Element deals with specific form controls.
Here is a complete list of all the methods related to Form Element.
