This fourth edition of the definitive reference to
JavaScript, a scripting language that can be embedded
directly in web pages, covers the latest version of the
language, JavaScript 1.5, as supported by Netscape 6 and
Internet Explorer 6. The book also provides complete
coverage of the W3C DOM standard (Level 1 and Level 2),
while retaining material on the legacy Level 0 DOM for
backward compatibility.

DOM Level 2 Events
Synopsis
void preventDefault( );
Description
This method tells the web browser not to perform the default action
(if any) associated with this event. For example, if the
type property is "submit", any event
handler called during any phase of event propagation can prevent the
form submission by calling this method. Note that if the
cancelable property of an Event object is
false, either there is no default action or there
is a default action that cannot be prevented. In either case, calling
this method has no effect.
