Mid(string,start[,length])

截取字符串中间的字符

Form:: Mid(string,start[,length])
Mid(Txt,n)
Mid(Txt,n,m)
Txt  is  string
n     is  starting place
m    is   length .... is not necessary : no length = to the end

读取一字符串中由指定的位置算起,截取指定的长度
Txt  : 字符串
n     :  起点位置
m    :  长度

Example code 1 -----
<%
Txt="www.ezer.com"
DomainName=mid(Txt,5)
response.write "Domain Name = "&DomainName
%>

Example code 2 ----------
<%
Txt="link.ezer.com"
DotPlace=instr(Txt,".")
SubName=mid(Txt,1,DotPlace-1)
response.write "Sub Name = "&SubName
%>
--------Ezer Tips ----------
when n start = 1 you will find
mid(Txt,1,DotPlace-1) 
same as 
left(Txt,DotPlace-1)

DotPlace=instr(Txt,".")
取出第一个点位置=5
5-1=DotPlace-1=指定长度
------- tips --------
mid 与 left 有似可有相辅的功能

----Sample code 1 result----
Dome Name = ezer.com

----Sample code 2 result----
Sub Name = link

网址名=ezer.com

副域名=link
