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.

Prototype Form Methods

NOTE − Make sure you at least have the version 1.6 of prototype.js.

S.No. Method & Description
1. disable()

Disables the form as whole. Form controls will be visible but uneditable.
2. enable()

Enables a fully or partially disabled form.
3. findFirstElement()

Finds first non-hidden, non-disabled form control.
4. focusFirstElement()

Gives keyboard focus to the first element of the form.
5. getElements()

Returns a collection of all form controls within a form.
6. getInputs()

Returns a collection of all INPUT elements in a form. Use optional type and name arguments to restrict the search on these attributes.
7. request()
