Web/API/Event/Event

The Event() constructor creates a new Event.

Syntax

new Event(typeArg[, eventInit]);

Values

typeArg

This is a DOMString representing the name of the event.

eventInit Optional

This is an EventInit dictionary, having the following optional fields:

bubbles Optional

A Boolean indicating whether the event bubbles. The default is false.

cancelable Optional

A Boolean indicating whether the event can be cancelled. The default is false.

composed Optional

A Boolean indicating whether the event will trigger listeners outside of a shadow root (see Event.composed for more details). The default is false.

Example

// create a look event that bubbles up and cannot be canceled

const evt = new Event("look", {"bubbles":true, "cancelable":false});
document.dispatchEvent(evt);

// event can be dispatched from any element, not only the document
myDiv.dispatchEvent(evt);
