4，ASP中應(yīng)用
以上是在客戶端腳本調(diào)試，和ASP也是大同小異：最主要的是函數(shù)功能。
<% text=rs("content") '將數(shù)據(jù)庫(kù)字段值賦到某變量上 i=10 '定義固定大小 if len(text)>i then '如果文本長(zhǎng)度大于給定的值 text=left(text,i) '則提取前段的i位的字符串 response.write (text&"...") else response.write (text) end if %> |
5，為了方便，做成函數(shù)
<% function conleft(content,i) if len(content)>i then content=left(content,i) response.write (content&"...") else response.write (content) end if end function %> |
以上為函數(shù)，下面就可以直接調(diào)用。
<%call conleft(rs("content"),10)%> |
OK，相信以后遇到這些問(wèn)題應(yīng)該是NO PROBLEM
為了解決中英文截取的問(wèn)題，建議大家使用如下函數(shù)：
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 |
