The Event property bubbles indicates whether the event bubbles up through the DOM or not.

Note: See Event bubbling and capture for more information on bubbling.

Syntax

var doesItBubble = Event.bubbles;

Value

A Boolean, which is true if the event bubbles up through the DOM.

Example

 function goInput(e) {
  // checks bubbles and
  if (!e.bubbles) {
     // passes event along if it's not
     passItOn(e); 
  }
  // already bubbling
  doOutput(e)
}

Note: Only certain events can bubble. Events that do bubble have this property set to true. You can use this property to check if an event is allowed to bubble or not.
