ASP根据视频格式正确的播放的函数

　　在给客户做个程序时,突然遇到个问题,就是产品页用户提交视频播放文件时,如何根据提交的网址内的视频格式进行正确的播放呢....郁闷了一会,想好了思路,说动手就动手...

　　思路是先取得文件的类型,并根据类型选择不同的网页播放器代码..三下五去二.....同时为了代码在以后的复用性,写成了通用的调用函数.方便以后在别的系统中调用..

　　现发布源代码如下:

Sub SelPlay(strUrl,strWidth,StrHeight)
Dim Exts,isExt
If strUrl <> "" Then
   isExt = LCase(Mid(strUrl,InStrRev(strUrl, ".")+1))
Else
   isExt = ""
End If
Exts = "avi,wmv,asf,mov,rm,ra,ram"
If Instr(Exts,isExt)=0 Then
 Response.write "非法视频文件"
Else
 Select Case isExt
  Case "avi","wmv","asf","mov"
   Response.write "<EMBED id=MediaPlayer src=http://www.chinahtml.com/0708/"&strUrl&" width="&strWidth&" height="&strHeight&" loop=""false"" autostart=""true""></EMBED>"
  Case "mov","rm","ra","ram"
   Response.Write "<OBJECT height="&strHeight&" width="&strWidth&" classid=clsid:CFCDAA03-8BE4-11cf-B84B-0020AFBBCCFA>"
   Response.Write "<PARAM NAME=""_ExtentX"" VALUE=http://www.chinahtml.com/0708/""12700"">"

 End Select
End If
End Sub
