UIEvent: UIEvent() constructor

The UIEvent() constructor creates a new UIEvent object.

Note: If you construct a synthetic event using this constructor, that event will not be trusted, for security reasons. Only browser-generated UIEvent objects are trusted and only trusted events trigger default actions.

Syntax

js

new UIEvent(type)
new UIEvent(type, options)

Parameters

type

A string with the name of the event. It is case-sensitive and browsers set it to load, unload, abort, error, or select.

options Optional

An object that, in addition of the properties defined in Event(), can have the following properties:

detail Optional

A number that is an event-dependent value associated with the event. It defaults to 0 and UIEvent.detail lists the semantic for standard events.

view Optional

The Window associated with the event. Its default value is null.

sourceCapabilities Optional

An InputDeviceCapabilities object which provides information about the physical device responsible for generating a touch event.

Result value

A new UIEvent object.
