Element: focusin event

{{APIRef("UI Events")}}

The focusin event fires when an element has received focus, after the {{domxref("Element/focus_event", "focus")}} event. The two events differ in that focusin bubbles, while focus does not.

The opposite of focusin is the {{domxref("Element/focusout_event", "focusout")}} event, which fires when the element has lost focus.

The focusin event is not cancelable.

Syntax

Use the event name in methods like {{domxref("EventTarget.addEventListener", "addEventListener()")}}, or set an event handler property.

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

onfocusin = (event) => { }

Event type

A {{domxref("FocusEvent")}}. Inherits from {{domxref("UIEvent")}} and {{domxref("Event")}}.
