bubbles Event Property

Find out if a specific event can bubble or not:

var x = event.bubbles;

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.

The numbers in the table specify the first browser version that fully supports the property.
