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,IstrText = String(Length,sChar)strText = strText & ValueLeftPad = Right(strText,Length)End Function

改一下最下面则为这样:

Function PadRight(Value,Length,sChar)Dim strText,IstrText = String(Length,sChar)strText = Value & strTextLeftPad = 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, SIF Not ISNumeric(Para) Or Not ISDate(DateAndTime) Then Exit FunctionY = CStr(Year(DateAndTime))M = CStr(Month(DateAndTime)):IF Len(M) = 1 Then M = \"0\" & MD = CStr(Day(DateAndTime)):IF Len(D) = 1 Then D = \"0\" & DH = CStr(Hour(DateAndTime)):IF Len(H) = 1 Then H = \"0\" & HF = CStr(Minute(DateAndTime)):IF Len(F) = 1 Then F = \"0\" & FS = CStr(Second(DateAndTime)):IF Len(S) = 1 Then S = \"0\" & SSelect Case ParaCase \"0\"ForMatDate = Y & \"-\" & M & \"-\" & D & \" \" & H & \":\" & F & \":\" & SCase \"1\"ForMatDate = Y & \"-\" & M & \"-\" & D & \" \" & H & \":\" & FCase \"2\"ForMatDate = Y & \"-\" & M & \"-\" & DCase \"3\"ForMatDate = Y & \"/\" & M & \"/\" & DCase \"4\"ForMatDate = Y & \"年\" & M & \"月\" & D & \"日\"Case \"5\"ForMatDate = M & \"-\" & D & \" \" & H & \":\" & FCase \"6\"ForMatDate = M & \"/\" & DCase \"7\"ForMatDate = M & \"月\" & D & \"日\"Case \"8\"ForMatDate = Y & \"年\" & M & \"月\"Case \"9\"ForMatDate = Y & \"-\" & MCase \"10\"ForMatDate = Y & \"/\" & MCase \"11\"ForMatDate = right(Y,2) & \"-\" &M & \"-\" & D & \" \" & H & \":\" & FCase \"12\"ForMatDate = right(Y,2) & \"-\" &M & \"-\" & DCase \"13\"ForMatDate = M & \"-\" & DCase ElseForMatDate = DateAndTimeEnd SelectEnd FunctionResponse.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
