ASP中实现字符部位雷同.NET里String工具的PadLeft和

论坛里又有人问起日期奈何名目化为:2004-08-09 05:02:20这样的名目:于是写了一个左(右)对齐的函数.这函数等价于.NET里String工具的PadLeft和PadRight函数

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

改一下最下面则为这样:

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

利用例子:日期显示

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")

万能时间补位代码

Public Function ForMatDate(DateAndTime, Para) '名目化日期(日期时间,名目) 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 & "https://www.jb51.net/" & M & "https://www.jb51.net/" & D Case "4" ForMatDate = Y & "年" & M & "月" & D & "日" Case "5" ForMatDate = M & "-" & D & " " & H & ":" & F Case "6" ForMatDate = M & "https://www.jb51.net/" & D Case "7" ForMatDate = M & "月" & D & "日" Case "8" ForMatDate = Y & "年" & M & "月" Case "9" ForMatDate = Y & "-" & M Case "10" ForMatDate = Y & "https://www.jb51.net/" & 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一段自动补位的函数

function formatsn(getnum,getbit) dim formatsnnum,formatsnpre,formatsnj formatsnnum = getbit – len(getnum) for formatsnj = 1 to formatsnnum formatsnpre = formatsnpre & "0" next formatsn = formatsnpre & getnum end function

利用要领

formatsn(getnum,getbit)

getnum 计数
getbit 共几位
