The Event.cancelBubble property is a historical alias to Event.stopPropagation(). Setting its value to true before returning from an event handler prevents propagation of the event. In later implementations, setting this to false does nothing. See Browser compatibility for details. 

Syntax

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

Example

elem.onclick = function(e) {
 // do cool things here
  e.cancelBubble = true;
}

1. Starting with Chrome 58 and Opera 45, setting this property to false does nothing, as per spec discussion.

2. Prior to Firefox 53, this property was defined on the UIEvent interface. See bug 1298970 for more details.
