来自FormatDateTime的经典ASP / VBSCRIPT 12小时格式

如何解决来自FormatDateTime的经典ASP / VBSCRIPT 12小时格式

我肯定会感谢您的帮助。我能够通过将值设置为2020年7月31日08:53:20这样的时间，将时间格式化为8:53 AM。

replace(replace(formatdatetime(formatdatetime(myRS("dateTime"),4)),":00 AM"," AM"),":00 PM"," PM")

但是我想有一种更有效的方法吗？

    ' The actual LCID.
    
    Response.LCID = 2057
    Response.CodePage = 65001
    
    
    Function AM_PM_Time(TheTime,ZeroPad)
        
        Dim actual_LCID,time_formatted,time_split_1,time_split_2
        
        ' Make sure the the date or time being passed is valid.
        
        If NOT isDate(TheTime) Then Exit Function
                        
        ' Make a note of the actual LCID.
        
        actual_LCID = Response.LCID
        
        ' Change the LCID to 1033 so time is formatted as 00:00:00 AM/PM.
        ' If your LCID is already 1033 you can delete the LCID code.
        
        Response.LCID = 1033
        
        ' Format the current date / time. 
        
        time_formatted = FormatDateTime(TheTime,3)
        
        ' Split the time stamp.
        
        time_split_1 = Split(time_formatted,":")
        
        ' Split the AM / PM.
        
        time_split_2 = Split(time_formatted," ")
        
        ' Revert the LCID back to its original value.
        
        Response.LCID = actual_LCID
        
        ' [Optional]
        ' Zero-pad the first number of the timestamp,for example: "07:45 PM" rather than "7:45 PM"
        
        If ZeroPad Then
        
            If Len(time_split_1(0)) = 1 Then time_split_1(0) = cStr("0" & time_split_1(0))
        
        End If
        
        ' Output the newly formatted time.
        
        AM_PM_Time = time_split_1(0) & ":" & time_split_1(1) & " " & time_split_2(1)
            
    End Function
    
    Response.Write AM_PM_Time(Now(),True) & "<br>"
    Response.Write AM_PM_Time("2020-08-17 09:00:00",False) & "<br>"
    Response.Write AM_PM_Time("14:55:00",True)
    
%>

示例输出：

9:00 AM
02:55 PM

    If Hour(Now) < 12 then
