Event.preventDefault( ) — cancel default action of an event
DOM Level 2 Events
void preventDefault( );
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.
