Laya.EventDispatcher off 删除侦听器

123黄

var eventDis = new Laya.EventDispatcher()

    eventDis.on('TEST_EVENT_DIS', this, someEventHandler, null)
    eventDis.off('TEST_EVENT_DIS', this, another_eventHandler, false)

off 怎样才能从 EventDispatcher 对象中删除侦听器？
我这样做 eventDis 还是监听TEST_EVENT_DIS

Laya_XS

eventDis.on('TEST_EVENT_DIS', this, someEventHandler, null)
eventDis.off('TEST_EVENT_DIS', this, someEventHandler)

这是正常的监听跟移除事件的方法；
