Utilities for dealing with form controls in the DOM.

This is a collection of methods that assist in dealing with form controls. They provide ways to focus, serialize, disable/enable or extract current value from a specific control.

Note that nearly all these methods are available directly on input, select, and textarea elements. Therefore, these are equivalent:

Form.Element.activate('myfield');
$('myfield').activate();

Naturally, you should always prefer the shortest form suitable in a situation. Most of these methods also return the element itself (as indicated by the return type) for chainability.
