ASP中实现字符部位类似.NET里String对象的PadLeft和PadRight函数

论坛里又有人问起日期怎样格式化为:2004-08-09 05:02:20这样的格式:于是写了一个左(右)对齐的函数.这函数等价于.NET里String对象的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

使用例子: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) '格式化日期(日期时间,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一段自动补位的函数

function formatsn(getnum,getbit)dim formatsnnum,formatsnpre,formatsnjformatsnnum = getbit – len(getnum)for formatsnj = 1 to formatsnnumformatsnpre = formatsnpre & "0"nextformatsn = formatsnpre & getnumend function

使用方法

formatsn(getnum,getbit)

getnum 计数
getbit 共几位
