Methods

    MDN Reference

    Returns EventTarget[]

  • The Event.initEvent() method is used to initialize the value of an event created using Document.createEvent().

    Parameters

    • type: string
    • Optionalbubbles: boolean
    • Optionalcancelable: boolean

    Returns void

    MDN Reference

  • The preventDefault() method of the Event interface tells the user agent that if the event does not get explicitly handled, its default action should not be taken as it normally would be.

    MDN Reference

    Returns void
