配合AJAX天氣預報的webService 之asp

因為發現AJAX目前跨域有點問題，只能在IE裡面設定才可以使用，所以自己就寫了個簡單ASP的webService，其實作用就是一個小偷程式，把雅虎的天氣抓了過來，然後產生XML。先從這裡開始吧，以後會考慮添加資料庫，這樣用戶端寫好後讀取速度就很快了。

習慣了用JS寫東西，一不小心ASP也全拿JS寫的，呵呵，有時間再改成VB。
我再鄙視他一下，FLASH是N年前就搞過的，時間雖然丟的有點長了，但是在AW的協助，慢慢就會有所起色。

總算平息了火，還算是又默默改變了一件事情。複製代碼 代碼如下:<%@LANGUAGE="JAVASCRIPT" CODEPAGE="65001"%>
