配合AJAX天气预报的webService 之asp


            因为发现AJAX目前跨域有点问题，只能在IE里面设置才可以使用，所以自己就写了个简单ASP的webService，其实作用就是一个小偷程序，把雅虎的天气抓了过来，然后生成XML。先从这里开始吧，以后会考虑添加数据库，这样客户端写好后读取速度就很快了。 习惯了用JS写东西，一不小心ASP也全拿JS写的，呵呵，有时间再改成VB。 我再鄙视他一下，FLASH是N年前就搞过的，时间虽然丢的有点长了，但是在AW的帮助，慢慢就会有所起色。 总算平息了火，还算是又默默改变了一件事情。复制代码 代码如下:<%@LANGUAGE="JAVASCRIPT" CODEPAGE="65001"%> <% Session.CodePage = "65001" Response.contentType="text/html" Response.Expires = 0 var N=Request("n") var Num=Request("id") var url="http://xml.weather.yahoo.com/forecastrss?p="+N+"&u=c&id="+Num;
