   編寫asp代碼截取字串:

  '函數名:SubstZFC

  '作 用:截字串,漢字一個算兩個字元,英文算一個字元

  '參 數:str ----原字串

  ' strlen ----截取長度

  '傳回值:截取後的字串

  '適用:標題截取指定字元,如果用LEFT截取,當有英文時就會出現取出來的標題明顯太短。

  '**************************************************

  Public Function SubstZFC(ByVal str, ByVal strlen)

  If str = "" Then

  SubstZFC = ""

  Exit Function

  End If

  Dim l, t, c, i, strTemp

  str = Replace(Replace(Replace(Replace(str, " ", " "), """, Chr(34)), ">", ">"), "<", "<")

  l = Len(str)

  t = 0

  strTemp = str

  strlen = CLng(strlen)

  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

  strTemp = Left(str, i)

  Exit For

  End If

  Next

  SubstZFC = Replace(Replace(Replace(Replace(strTemp, " ", " "), Chr(34), """), ">", ">"), "<", "<")

  End Function
