This feature is no longer recommended. Though some browsers might still support it, it may have already been removed from the relevant web standards, may be in the process of being dropped, or may only be kept for compatibility purposes. Avoid using it, and update existing code if possible; see the

UIEvent.cancelBubble
property indicates if event bubbling for this event has been canceled or not. It is set to
false
by default, allowing 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.
使用
Event.stopPropagation()
instead of this non-standard method.
event.cancelBubble = bool; var bool = event.cancelBubble;
This property is not part of any specification.
Although the similar
Event.cancelBubble
property was included in
an old Working Draft of W3C DOM Level 2
. Microsoft has a
description of it on MSDN
