OBJECT:
Textarea
A Textarea object provides a multi-line field in which the user can enter data and is created with every instance of an HTML <TEXTAREA> tag on a form. These objects are then stored in the elements array of the parent form and accessed using either the name defined within the HTML tag or an integer (with '0' being the first element defined, in source order, in the specified form).
PROPERTIES
defaultValue Property
This property sets or returns a string indicating the initial value of the Textarea object. The value of this property initially reflects the value between the start and end <TEXTAREA> tags. Use of the defaultValue property, which can be done at any time, will override the original value.
Syntax: object.defaultValue[ = "newdefaultvalue"]
form Property
This property returns a reference to the parent Form of the Textarea
object.
Syntax: object.form
name Property
This property sets or returns the value of the Textarea object's
name attribute.
Syntax: object.name
type Property
Every element on a form has an associated type property. In the
case of a Textarea object, the value of this property is always
"textarea".
Syntax: object.type
value Property
This property sets or returns the Textarea object's value
attribute. This is the text that is actually displayed in the Textarea and can be set at any time with any changes being immediately displayed.
Syntax: object.value

object.
