% 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,"nbsp;"," "),"quot;",chr(34)),"gt;",">"),"lt;","") 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," ","nbsp;"),chr(34),"quot;"),">","gt;"),"","lt;") End Function |
