Event.constructor

The Event() constructor creates a new Event.

Syntax

 event = new Event(typeArg, eventInit);

Values

typeArg

Is a DOMString representing the name of the event.

eventInit Optional

Is an EventInit dictionary, having the following fields:

• "bubbles": (Optional) A Boolean indicating whether the event bubbles. The default is false.
• "cancelable": (Optional) A Boolean indicating whether the event can be canceled. The default is false.
• "scoped": (Optional) A Boolean indicating whether the given event bubbles. If this value is true, deepPath will only contain a target node.
• "composed": (Optional) A Boolean indicating whether the event will trigger listeners outside of a shadow root. The default is false.

Example

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

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