this._onlineScheduleHandle = this.updateOnlineTime.bind(this);
            cc.director.getScheduler().unschedule(this._onlineScheduleHandle,this);
            cc.director.getScheduler().schedule(this._onlineScheduleHandle,this,1.1,cc.REPEAT_FOREVER,false,"keyCountDownTime");

Cocos2d-js中，回调函数一定要先保存起来，例如 this._onlineScheduleHandle = this.updateOnlineTime.bind(this);@H_502_3@

其次 cc.director.getScheduler().schedule(this._onlineScheduleHandle,"keyCountDownTime");这个参数一定要写全，否则出问题。
