4,ASP中应用
以上是在客户端脚本调试,和ASP也是大同小异:最主要的是函数功能。
<%
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
