还有多少人在玩2048现在都4096了

《2048》是比较流行的一款数字游戏。原版2048首先在github上发布，原作者是Gabriele Cirulli。它是基于《1024》和《小3传奇》的玩法开发而成的新型数字游戏[1] 。
随后2048便出现各种版本，走各大平台。由Ketchapp公司移植到IOS的版本最为火热，现在约有1000万下载，其名字跟原版一模一样。衍生版中最出名的是《2048六边形》版本，

先后在全球81个国家中的board game中排进了前200。

安卓版非常火爆的有《挑战2048》，其2.0.0版以后还加入了双人对战。

其次比较特别的有2048中国朝代版。更有2048自定义版，可以自己定义文字和图片。《2048》是IOS中流行的一款。

大家好、开始

     首先就上图：

 我的思路：

     获取客户端的ip--》找到ip的所属地--》获取该地方的下级区县、显示到页面。

代码:

 Js:

if (province == "北京") {
    return  ["东城", "西城", "朝阳", "丰台", "怀柔", "海淀", "密云", "房山", "通州", "昌平", "北京"];

        // to retrieve a list of classes.
        var classes = el.className.replace(/^s+|s+$/g, '').split(/s+/);
        for (var i = 0; i < classes.length; i++) {
