    在電子商務或一些ASP應用程序中，經常要用到地區的選擇。
    中國有35個省或市或地區，我們在選擇一個省市，希望能夠立即彈出對應的省以供選擇。這功能可以用javascript來
實現。但是中國擁有非常縱多的城市，假如用Javascript起來，將會是一個不小的JavaScript,像ChinaBig的網站的選擇下
拉框對應的JS內容竟有38.5K 之多，嚴重影響了網頁的瀏覽速度。今日我對這些數據進行了重組，直接用數據賦值，并將
變量名改為一個字母，數據減小到只有7670 Bytes。從此瀏覽速度大大改觀，網站也用不著改變省就要重復刷新，　而代
價僅僅是這7670個字節。

下面是City.JS的內容.

I=new Array;
N=new Array;
I[03]=new Array(0,500,501,502,503,504,505,506,507,508,509,510,511);
N[03]=new Array("請選擇","東城區","西城區","崇文區","宣武區","朝陽區","豐臺區","石景山區","海淀區","門頭溝
區","房山區","郊縣","其他地區");
I[26]=new Array(0,580,581,582,583,584,585,586,587,588,589,590,591,592,593,594,595);
N[26]=new Array("請選擇","黃浦區","南市區","盧灣區","徐匯區","長寧區","靜安區","普陀區","閘北區","虹口
區","楊浦區","閔行區","寶山區","郊縣","嘉定區","浦東新區","其他地區");
I[29]=new Array(0,600,601,602,603,604,605,606,607,608,609,610,611,612,613,614);

I[35]=new Array(0,638,639,640,641,642);
N[35]=new Array("請選擇","涪陵區","萬州區","黔江地區","市區","其他地區");
I[34]=new Array(0,637,1,3,4,5,6,17,18,21,23,24,25);
N[34]=new Array("請選擇","其他地區","溫州市","杭州市","寧波市","嘉興市","紹興市","麗水地區","湖州市","金華
市","臺州市","舟山市","衢州市");
I[07]=new Array(0,86,89,90,92,93,94,96,97,520,521,522,523,524,525);
N[07]=new Array("請選擇","北海市","桂林市","河池地區","柳州市","南寧市","欽州市","梧州市","玉林地區","防城
