在电子商务或一些ASP应用程序中，经常要用到地区的选择。
中国有35个省或市或地区，我们在选择一个省市，希望能够立即弹出对应的省以供选择。这功能可以用javascript来
实现。但是中国拥有非常纵多的城市，如果用JavaScript起来，将会是一个不小的JavaScript,像ChinaBig的网站的选择下
拉框对应的JS内容竟有38.5K 之多，严重影响了网页的浏览速度。今日我对这些数据进行了重组，直接用数据赋值，并将
变量名改为一个字母，数据减小到只有7670 Bytes。从此浏览速度大大改观，网站也用不着改变省就要重复刷新， 而代
价仅仅是这7670个字节。
下面是City.JS的内容.
