DOM:event.cancelBubble
From MDC
[edit] Summary
Deprecated
Indicates if event bubbling for this event has been canceled or not.
[edit] Syntax
event.cancelBubble = bool bool = event.cancelBubble
bool is the boolean value of true or false.
[edit] Notes
cancelBubble is set to false by default. This allows the event to bubble up the DOM, if it is a bubbleable event. Setting this property to true stops the event from bubbling up the DOM. Not all events are allowed to bubble up the DOM.
Use event.stopPropagation() instead of this non-standard method.
