CustomEvent.initCustomEvent()

Deprecated
This feature has been removed from the Web standards. Though some browsers may still support it, it is in the process of being dropped. Do not use it in old or new projects. Pages or Web apps using it may break at any time.

The CustomEvent.initCustomEvent() method initializes a CustomEvent object. If the event has already been dispatched, this method does nothing.

Events initialized in this way must have been created with the Document.createEvent() method. This method must be called to set the event before it is dispatched, using EventTarget.dispatchEvent(). Once dispatched, it doesn't do anything anymore.

Do not use this method anymore, as it is deprecated.

Instead use specific event constructors, like CustomEvent(). The page on Creating and triggering events gives more information about the way to use these.

Syntax

Parameters

type
Is a DOMString containing the name of the event.
canBubble
