<% text=rs("content") '将数据库字段值赋到某变量上 i=10 '定义固定大小 if len(text)>i then '如果文本长度大于给定的值 text=left(text,i) '则提取前段的i位的字符串 response.write (text&"...") else response.write (text) end if %>
5，为了方便，做成函数
<% function conleft(content,i) if len(content)>i then content=left(content,i) response.write (content&"...") else response.write (content) end if end function %>
以上为函数，下面就可以直接调用。
<%call conleft(rs("content"),10)%>
OK，相信以后遇到这些问题应该是NO PROBLEM
为了解决中英文截取的问题，建议大家使用如下函数：
Function gotTopic(str,strlen) if str="" then gotTopic="" exit function end if dim l,t,c, i str=replace(replace(replace(replace(str," "," "),""",chr(34)),">",">"),"<","<") l=len(str) t=0 for i=1 to l c=Abs(Asc(Mid(str,i,1))) if c>255 then t=t+2 else t=t+1 end if if t>=strlen then gotTopic=left(str,i) & "…" exit for else gotTopic=str end if next gotTopic=replace(replace(replace(replace(gotTopic," "," "),chr(34),"""),">",">"),"<","<") End Function
