FocusEvent: relatedTarget property

Baseline Widely available

This feature is well established and works across many devices and browser versions. It’s been available across browsers since July 2015.

The relatedTarget read-only property of the FocusEvent interface is the secondary target, depending on the type of event:

Event name target relatedTarget
blur The EventTarget losing focus The EventTarget receiving focus (if any).
focus The EventTarget receiving focus The EventTarget losing focus (if any)
focusin The EventTarget receiving focus The EventTarget losing focus (if any)
focusout The EventTarget losing focus The EventTarget receiving focus (if any)

Note that many elements can't have focus, which is a common reason for relatedTarget to be null. relatedTarget may also be set to null for security reasons, like when tabbing in or out of a page.

MouseEvent.relatedTarget is a similar property for mouse events.

Value

An instance of EventTarget.
