Javascript Textarea Object
The Javascript 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 Javascript Textarea object by indexing the elements array (by number or name) of the corresponding form or by using getElementById().
