Non-standard
This feature is non-standard and is not on a standards track. Do not use it on production sites facing the Web: it will not work for every user. There may also be large incompatibilities between implementations and the behavior may change in the future.

Deprecated
This feature has been removed from the Web standards. Though some browsers may still support it, it is in the process of being dropped. Do not use it in old or new projects. Pages or Web apps using it may break at any time.

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.

Use Event.stopPropagation() instead of this non-standard method.

Syntax

event.cancelBubble = bool;
var bool = event.cancelBubble;

Specification

This property is not part of any specification.
