Web/API/Event/bubbles

The bubbles read-only property of the Event interface indicates whether the event bubbles up through the DOM or not.

Note: See [[../../../../Learn/JavaScript/Building_blocks/Events#Event_bubbling_and_capture|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 handleInput(e) {
  // Checks whether the event bubbles and ...
  if (!e.bubbles) {
    // ... passes the event along if does 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.
