A read-only reference to the Form object that contains the Hidden element.
A read-only string, set by the HTML NAME attribute, that specifies the name of the Hidden element. This is also the name that can be used to reference the Hidden element as a property of its form.
A read-only string that specifies the type of this form element. For Hidden elements, it has the value "hidden." Available in Navigator 3.0 and later.
A read/write string, initially set by the HTML VALUE attribute, which specifies arbitrary data to be transmitted to the server when the form is submitted. This data is never visible to the user.
A Hidden element is created with a standard HTML <INPUT> tag:
<FORM> ... <INPUT TYPE="hidden" specifies that this is a Hidden element [ NAME="name" ] a name that can later be used to refer to this element specifies the name property [ VALUE="value" ] the value transmitted when the form is submitted specifies the initial value of the value property > ... </FORM>
The Hidden element is an invisible form element that allows arbitrary data to be transmitted to the server when the form is submitted. You can use a Hidden element when you want to transmit additional information, besides the user's input data, to the server.
Cookies can also be used to transmit data from client to server. An important difference between hidden form elements and cookies, however, is that cookies are persistent on the client side.
