4,ASP中應用
以上是在客戶端腳本調試,和ASP也是大同小異:最主要的是函數功能。
<%
text=rs("content") '將數據庫字段值賦到某變量上
i=10 '定義固定大小
if len(text)>i then '如果文本長度大於給定的值
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
<%
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,下面就可以直接調用。
<%call conleft(rs("content"),10)%>
OK,相信以後遇到這些問題應該是NO PROBLEM
為了解決中英文截取的問題,建議大家使用如下函數:
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
