ASP对很长的文章做分页输出
阅读: 1 评论: 0 作者: eng308 发表于 2010-02-03 10:33 原文链接
利用统计文章字数，然后达到一定字数就截断输出，但是分页的内容就会在莫名其妙的地方截断，不是很友好。
很简单，在要截断的地方附近找下面的符号:
；’”？。！;'".!
如果后面存在<p>或<br>就分页。主要是要研究文章的格式。
<%
if Request.ServerVariables("Content_Length") > 0 then
content = Request.Form("textarea1")
PageLength = 1000 '每页字数
CLength = Len(content)
PageCount = Int(Clength/PageLength) + 1 '计算页数
dim PageArray
redim PageArray(PageCount)
Seperator = Array(chr(13),chr(10),"。","！","？","；","，","”","’") '分隔符
PageArray(0) = 0
Pos = 0
for j=0 to ubound(Seperator)
Pos = instr(PageArray(i)+900,content,Seperator(j)) 'PageArray(i)+900 附近位置是100字，1-999可调
while Pos > 0 and Pos < (i+1)*PageLength and Pos > i*PageLength
PageArray(i) = Pos
Pos = instr(Pos+PageLength,content,Seperator(j))
wend
if PageArray(i) > 0 then
Response.Write "0:i| "&PageArray(i)&"<br>"&j&":j"&Seperator(j)&"<br>"
j = j + ubound(Seperator) + 1
end if
next
for i=1 to PageCount-1
PageArray(i) = 0
Pos = 0
for j=0 to ubound(Seperator)
Pos = instr(PageArray(i-1)+950,content,Seperator(j))
while Pos > 0 and Pos < (i+1)*PageLength and Pos > i*PageLength
PageArray(i) = Pos
Pos = instr(Pos+PageLength,content,Seperator(j))
wend
if PageArray(i) > 0 then
Response.Write i&":i| "&PageArray(i)&"<br>"&j&":j"&Seperator(j)&"<br>"
j = j + ubound(Seperator) + 1
end if
next
next
output = mid(content,1,PageArray(0))
output = replace(output,chr(13),"<br>")
Response.Write "<br><br>第1段<br>"
Response.Write output
for i=1 to PageCount-2
output = mid(content,PageArray(i-1)+1,PageArray(i)-PageArray(i-1))
output = replace(output,chr(13),"<br>")
Response.Write "<br><br>第"&i+1&"段<br>"
Response.Write output
next
'最后一段的输出就没写了
else
