cocos2d-x JS 获取当前系统时间(解决屏幕双击点击事件)

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

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

 operateMyTile : function(sender, eventType) {//屏幕点击事件函数处理

     if(this.unlock) {

         if (eventType == ccui.Widget.TOUCH_BEGAN) {　//在此处判断，点下触碰生效 Touch_began
             this.newSender = sender.clone();
             sender.getParent().addChild(this.newSender, 100);
             //var ddd=sender.getPosition();
             this.newSender.setScale(1.3);
             this.timeCount ++ ;

             var t = new Date();
              var hours = (t.getHours() > 9) ? t.getHours() : ("0" + t.getHours());//获取当前系统小时
             // var minutes = (t.getMinutes() > 9) ? t.getMinutes() : ("0" + t.getMinutes());
             var seconds = t.getMilliseconds();//其实就这一句就可以了
             //var str = "" + hours + ":" + minutes+ ":" + seconds;

             this.sender = sender;

             if(sender.seconds != null){
                 var ints = t.getMilliseconds() - sender.seconds;
                 if(1000 > ints){//核心判断在这里(我是判断在1秒内点击两次，1000毫秒等于1秒)
