OBJECT: Form
Forms allow us to prompt
a user for input using elements such as radio buttons, checkboxes and
selection lists. Data gathered in this manner can then be posted to a
server for processing. A form is created by enclosing HTML controls
and other elements within <form></form> tags. A page
can contain as many forms as required, but they cannot be overlapping
or nested (the closing </form> tag of a form must precede
the opening tag of any subsequent form).
PROPERTIES
action Property
This property specifies the URL address to which the data gathered by
the form will be submitted. An email address can also be specified
using the 'mailto:anybody@anywhere.com' syntax.
Syntax: object.action
= URL
elements Property
This property is an array containing an object for each element on the
form. These objects (checkboxes, radio buttons, etc.) are added
to the array in the order that they appear in the document's source code.
Syntax: object.elements
encoding Property
This property sets the MIME type that is used to encode the data gathered
by the elements in a form for submission when using the post method.
This property initially contains a string reflecting the enctype
attribute of the form tag, but using encoding will override
this.
Syntax: object.encoding
length Property
This property returns the number of elements in a form.
Syntax: object.length
method Property
This property is a string specifying how information input in a form is submitted to the server.
This should return either 'get', which is the default, or 'post'.

the name attribute of the <form> tag.
