Synopsis

                  form.elements[i] 
form.elements.length

Description

form.elements[] is an array of the form input objects in form. The array has elements.length items in it. These items may be of any of the form input element types: Button, Checkbox, Hidden, Password, Radio, Reset, Select, Submit, Text, and Textarea. These form input objects appear in the array in the same order that they appear in the HTML source code for the form.

Usage

If an item in the form .elements[] array has been given a name with the name=" name " attribute of its HTML <input> tag, that item’s name becomes a property of form, and this property refers to the item. Thus, it is possible to refer to input objects by name instead of by number:

                  form.name

Referring to elements by name is usually easier, so it is a good idea to specify the name attribute for all form elements.
