[ASP]Left与Right的应用

<%

Left(Request.Servervariables("url"),InstrRev(Request.Servervariables("url"),"/"))

Right(Request.Servervariables("url"),len(Request.Servervariables("url"))-InstrRev(Request.Servervariables

("url"),"/"))

 %>

执行后:

 /jclser/archive/2008/10/23/

1317997.html

明白了吗? Left可以获得路径,Right可以获得文件名...

顺便再补充些Servervariables知识吧:

执行:

<%
for each x in Request.ServerVariables
response.write(x &" : "&Request.ServerVariables (x)& "<br />")
next
%>
