HTML Syntax

<input
   datafld = fieldname
   dataformatas = html | text
   datasrc = #id
   id = value
   name = name
   type = hidden
   value = value
   event = script
>

The INPUT type=hidden element is used to create a control that is not rendered but whose value is submitted with a form. This control type provides a mechanism for storing and delivering information to the receiving program without user interaction.

The hidden input type presents no control to the user. Note that the element is not truly hidden; a user can see it by simply viewing the document source.

INPUT Members

The code below creates a hidden input control named keyPass that stores, for example, a dynamically assigned access code.

<form>
   ... other forms controls here ...
   <input type="hidden" name="keyPass" value="">
</form>

The control's value may be dynamically encrypted based on other form inputs, by a script that is triggered by the form's onsubmit event handler. This data then gets sent to the receiving program when the form is submitted.
