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

2020-07-04 17:51bpfish ASP教程

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,formatsnj

									formatsnnum = getbit – len(getnum)

									for formatsnj = 1 to formatsnnum

									formatsnpre = formatsnpre & "0"

									next

									formatsn = formatsnpre & getnum

									end function
