Function addEventListenerTo

Adds an event listener for the given event name to the given target.

Like EventTarget:addEventListener but it handles options object in case the browser does not support those. Does not support the signal option unless browser natively supports that.

  • addEventListenerTo(
        target: EventTarget,
        eventType: string,
        handler: EventListenerOrEventListenerObject,
        options?: boolean | AddEventListenerOptions,
    ): boolean

    Parameters

    • target: EventTarget
    • eventType: string
    • handler: EventListenerOrEventListenerObject
    • Optionaloptions: boolean | AddEventListenerOptions

    Returns boolean

    true if successfully added, or false if the same handler has already been added by us, or if the handler is not a valid event listener.
