off: (<TData>(type: string, listener?: ((event: TData) => void)) => void)

Remove event listener If no listener is specified, all listeners will be removed

Type declaration

    • <TData>(type, listener?): void

    • Type Parameters

      • TData = unknown

      Parameters

      • type: string

        Event type

      • Optionallistener: ((event: TData) => void)

        Event listener

          • (event): void

          • Parameters

            Returns void

      Returns void

on

on: (<TData, TType>(type: TType, listener: EventListener<TData, TType>, thisArg?: ThisType<unknown>) => void)

Add new event listener

Type declaration

    • <TData, TType>(type, listener, thisArg?): void

    • Type Parameters

      • TData = unknown
      • TType extends string = string

      Parameters

      • type: TType

        Event type. If the event type is xAPI, the listener's event parameter will be of type XAPIEvent. Any dispatched XAPIEvent will trigger the xAPI event.

      • listener: EventListener<TData, TType>

        Event listener

      • OptionalthisArg: ThisType<unknown>

        Optionally specify the listener's this value

      Returns void

Throws

listener must be a function

once

once: (<TData, TType>(type: TType, listener: EventListener<TData, TType>, thisArg?: ThisType<unknown>) => void)

Add new event listener that will be fired only once

Type declaration

    • <TData, TType>(type, listener, thisArg?): void

    • Type Parameters

      • TData = unknown
      • TType extends string = string

      Parameters

      • type: TType

        Event type. If the event type is xAPI, the listener's event parameter will be of type XAPIEvent. Any dispatched XAPIEvent will trigger the xAPI event.

      • listener: EventListener<TData, TType>

        Event listener

      • OptionalthisArg: ThisType<unknown>

        Optionally specify the listener's this value

      Returns void

Throws

listener must be a function

trigger

trigger: (<TData>(event: unknown, eventData?: TData, extras?: {
    bubbles?: boolean;
    external?: boolean;
}) => void)

Dispatch event

Type declaration

    • <TData>(event, eventData?, extras?): void

    • Type Parameters

      • TData = unknown
