  • set oppositeIndex(value): void
  • 参数

    返回 void

    Index of the opposite page. ie. If the current index is 0, the opposite index will be 1, else if the current index is greate than 0, the opposite index will be 0.

    相反页面的索引。即如果当前索引为0,则相反索引为1;如果当前索引大于0,则相反索引为0。

方法

  • 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.

    Dispatch an event.

    派发事件。

  • 参数

    • type: string

    返回 boolean

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

    Check if the EventDispatcher object has any listeners registered for a specific type of event.

    检查 EventDispatcher 对象是否为特定事件类型注册了任何侦听器。

  • 参数

    • type: string

      The type of event.

    • listener: Function

      The listener function.

    返回 EventDispatcher

    This EventDispatcher object.
