Textarea Object
The Textarea object represents a text-area in an HTML form.
For each instance of an HTML <textarea> tag in a form, a
Textarea object is created.
You can access a Textarea object by indexing the elements
array (by number or name) of the corresponding form or by using
getElementById().
