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.
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.
