論壇里又有人問起日期怎樣格式化為:2004-08-09 05:02:20這樣的格式:于是寫了一個左(右)對齊的函數(shù).這函數(shù)等價于.NET里String對象的PadLeft和PadRight函數(shù)

Function PadLeft(Value,Length,sChar)  Dim strText,I  strText = String(Length,sChar)  strText = strText & Value  LeftPad = Right(strText,Length)End Function

改一下最下面則為這樣:

Function PadRight(Value,Length,sChar)  Dim strText,I  strText = String(Length,sChar)  strText = Value & strText  LeftPad = Left(strText,Length)End Function

使用例子:日期顯示

AA = year(now) & "-" & PadLeft(month(now),2,"0") & "-" & PadLeft(Day(now),2,"0") & " " & PadLeft(Hour(now),2,"0") & ":" & PadLeft(Minute(now),2,"0") & ":" & PadLeft(Second(now),2,"0")

萬能時間補位代碼

Public Function ForMatDate(DateAndTime, Para) '格式化日期(日期時間,格式) Dim Y, M, D, H, F, S IF Not ISNumeric(Para) Or Not ISDate(DateAndTime) Then Exit Function Y = CStr(Year(DateAndTime)) M = CStr(Month(DateAndTime)):IF Len(M) = 1 Then M = "0" & M D = CStr(Day(DateAndTime)):IF Len(D) = 1 Then D = "0" & D H = CStr(Hour(DateAndTime)):IF Len(H) = 1 Then H = "0" & H F = CStr(Minute(DateAndTime)):IF Len(F) = 1 Then F = "0" & F S = CStr(Second(DateAndTime)):IF Len(S) = 1 Then S = "0" & S Select Case Para   Case "0"     ForMatDate = Y & "-" & M & "-" & D & " " & H & ":" & F & ":" & S   Case "1"     ForMatDate = Y & "-" & M & "-" & D & " " & H & ":" & F   Case "2"     ForMatDate = Y & "-" & M & "-" & D   Case "3"     ForMatDate = Y & "/" & M & "/" & D   Case "4"     ForMatDate = Y & "年" & M & "月" & D & "日"   Case "5"     ForMatDate = M & "-" & D & " " & H & ":" & F   Case "6"     ForMatDate = M & "/" & D   Case "7"     ForMatDate = M & "月" & D & "日"   Case "8"     ForMatDate = Y & "年" & M & "月"   Case "9"     ForMatDate = Y & "-" & M   Case "10"     ForMatDate = Y & "/" & M   Case "11"     ForMatDate = right(Y,2) & "-" &M & "-" & D & " " & H & ":" & F   Case "12"     ForMatDate = right(Y,2) & "-" &M & "-" & D   Case "13"     ForMatDate = M & "-" & D   Case Else     ForMatDate = DateAndTime End Select End Function Response.Write ForMatDate(Now,"2")

asp一段自動補位的函數(shù)

function formatsn(getnum,getbit)dim formatsnnum,formatsnpre,formatsnjformatsnnum = getbit
