Definition and Usage

The bubbles event property returns a Boolean value that indicates whether or not an event is a bubbling event.

Event bubbling directs an event to its intended target, it works like this:

  • A button is clicked and the event is directed to the button
  • If an event handler is set for that object, the event is triggered
  • If no event handler is set for that object, the event bubbles up (like a bubble in water) to the objects parent

The event bubbles up from parent to parent until it is handled, or until it reaches the document object.
