cancelBubble property
      
      bool
      get
      cancelBubble
      
    
    
The cancelBubble property of the Event
interface is deprecated. Use Event.stopPropagation instead.
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.
Implementation
external bool get cancelBubble;
      
      set
      cancelBubble
      (bool value) 
      
    
    
    
Implementation
external set cancelBubble(bool value);
