Element: focusout event

Limited availability

This feature is not Baseline because it does not work in some of the most widely-used browsers.

The focusout event fires when an element has lost focus, after the blur event. The two events differ in that focusout bubbles, while blur does not.

The opposite of focusout is the focusin event, which fires when the element has received focus.

The focusout event is not cancelable.

Syntax

Use the event name in methods like addEventListener().

addEventListener("focusout", (event) => { })

Note: There is no onfocusout event handler property for this event.

Event type

A FocusEvent. Inherits from UIEvent and Event.

Event properties

This interface also inherits properties from its parent UIEvent, and indirectly from Event.

FocusEvent.relatedTarget: The element receiving focus, if any.
