上次還是CSDN裡的朋友回答的,我複製了下來。原文如下
===========================
利用統計文章字數,然後達到一定字數就截斷輸出,但是分頁的內容就會在莫名其妙的地方截斷,不是很友好。
很簡單,在要截斷的地方附近找下面的符號:
;'”?。!;'".!
如果後面存在<p>或<br>就分頁。主要是要研究文章的格式。
<%
if Request.ServerVariables("Content_Length") > 0 then
content = Request.Form("textarea1")PageLength = 1000 '每頁字數
CLength = Len(content)
PageCount = Int(Clength/PageLength) + 1 '計算頁數dim PageArray
redim PageArray(PageCount)Seperator = Array(chr(13),chr(10),"。","!","?",";",",","”","'") '分隔字元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可調
while Pos > 0 and Pos < (i+1)*PageLength and Pos > i*PageLength
PageArray(i) = Pos
Pos = instr(Pos+PageLength,content,Seperator(j))
wendif PageArray(i) > 0 then
Response.Write "0:i¦ "&PageArray(i)&"<br>"&j&":j"&Seperator(j)&"<br>"
j = j + ubound(Seperator) + 1
end if
nextfor 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

定義有 每頁面長度 MaxLength
文本總長度 TotalLength
掃描文章中每一個段尾處的硬斷行符號
並計算該處長度
一旦超過 MaxLength 則分成第一頁
刪除此硬斷行符號前的部分 重複上述操作。
