字節數最小的中國城市JavaScrip列表

ASP精品屋 紅頭繩 2001-5-28


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，如果用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.
