Dynamic HTML: The Definitive Reference

Name

hidden — NN 3 IE 4 DOM 1

Synopsis

The hidden object is a form control generated with an INPUT element whose TYPE attribute is set to "hidden". This element has no event handlers, because users do not interact directly with the element. Be aware that any values assigned to a hidden object are removed if the user reloads the page. In other words, it does not function as a persistent store. The Win32 version of Internet Explorer 4 exposes many more properties than are listed below. Most of these are included in the internal object definition for consistency across other text-oriented form controls, but have no significance for a hidden object.
