event

  • event(type: string, data?: any): boolean

    参数

    • type: string

      The type of event.

    • 可选data: any

      (Optional) Data to pass to the callback. If multiple parameters p1, p2, p3, ... need to be passed, use an array structure such as [p1, p2, p3, ...]. If a single parameter p needs to be passed and p is an array, use a structure such as [p]. For other single parameters p, you can directly pass parameter p. If data is Event.EMPTY, it means passing an Event object to the callback function. Note that it is not passing Event.TEMP, but an independent Event object.

    返回 boolean

    True if there are listeners for this event type, false otherwise.

    En

    Dispatch an event.

    Zh

    派发事件。

hasListener

  • hasListener(type: string): boolean

    参数

    • type: string

      The type of event.

    返回 boolean

    True if a listener of the specified type is registered, false otherwise.
