The Event() constructor creates a new Event.


new Event(typeArg[, eventInit]);


This is a DOMString representing the name of the event.
eventInit Optional
This is an EventInit dictionary, having the following optional fields:
  • bubbles: a Boolean indicating whether the event bubbles. The default is false.
  • cancelable: a Boolean indicating whether the event can be cancelled. The default is false.
  • composed: a Boolean indicating whether the event will trigger listeners outside of a shadow root (see Event.composed for more details). The default is false.


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

var evt = new Event("look", {"bubbles":true, "cancelable":false});

// event can be dispatched from any element, not only the document
