记录一下，好开心，感觉今天自己又学到东西了，对于屏幕双击事件本来还毫无头绪的，今天得以解决总算没白费加班，其实原理很简单； 就是在点击事件里做一个判断，这个判断就是需要获取当前系统的时间的毫秒差，第一次点击的时候直接return， 然后进行第二次点击的时候也进行记录，判断两者之间的时间差，进行函数响应，就可以解决了

1 timeUpdate : function() {2     var t = new Date();3     var hours = (t.getHours() > 9) ? t.getHours() : ("0" + t.getHours());//获取系统小时(其实并没有什么卵用)4     var minutes = (t.getMinutes() > 9) ? t.getMinutes() : ("0" + t.getMinutes());//获取系统分钟(也并没有什么卵用)5 　　var seconds = (t.getMilliseconds() > 9) ? t.getMilliseconds() : ("0" + t.getMilliseconds());//这个是毫秒(需要用到哦)6 var str = "" + hours + ":" + minutes+ ":" +seconds;//拼接起来就是时间了7     this.tfClock.setString(str);8 },

1 operateMyTile : function(sender, eventType) {
   //屏幕点击事件函数处理 2  3     if(this.unlock) { 4  5         if (eventType == ccui.Widget.TOUCH_BEGAN) {　//在此处判断，点下触碰生效 Touch_began  6             this.newSender = sender.clone(); 7             sender.getParent().addChild(this.newSender, 100); 8             //var ddd=sender.getPosition(); 9             this.newSender.setScale(1.3);10             this.timeCount ++ ;11 12             var t = new Date();13              var hours = (t.getHours() > 9) ? t.getHours() : ("0" + t.getHours());//获取当前系统小时14             // var minutes = (t.getMinutes() > 9) ? t.getMinutes() : ("0" + t.getMinutes());15             var seconds = t.getMilliseconds();//其实就这一句就可以了16             //var str = "" + hours + ":" + minutes+ ":" + seconds;17 18             this.sender = sender;19 20             if(sender.seconds != null){21                 var ints = t.getMilliseconds() - sender.seconds;22                 if(1000 > ints){
