Cocos2d-js创建构造注册事件监听回调函数

registerEventListener:function () {    var onListener = function(event) {        if (event._data.type == "showFail") {            this.youAreFail();        }    }.bind(this);    this.listener = cc.EventListener({        event: cc.EventListener.CUSTOM,        eventName: "ResultUiLayer",        callback: onListener    });    cc.eventManager.addListener(this.listener, 1);},onExit:function () {    cc.removeEventListener(this.listener);}
