Constructors

FocusEvent()

public FocusEvent()

FocusEvent(string, FocusEventInit)

The FocusEvent() constructor returns a newly created
FocusEvent object with an optional EventTarget. When the
event has both a source and a destination, the relatedTarget value must be
set to the other target.

public FocusEvent(string type, FocusEventInit eventInitDict = null)

Parameters

type string

eventInitDict FocusEventInit

Remarks

Properties

RelatedTarget

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

[Value("relatedTarget")]
public EventTarget? RelatedTarget { get; }

Property Value

EventTarget

An instance of EventTarget.

Remarks

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.

RelatedTarget is a similar property for mouse events.
