ASP根据提交的视频格式进行正确的播放的函数

　　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=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=12700>
Response.Write <PARAM NAME=_ExtentY VALUE=9525>
Response.Write <PARAM NAME=AUTOSTART VALUE=-1>
Response.Write <PARAM NAME=SHUFFLE VALUE=0>
Response.Write <PARAM NAME=PREFETCH VALUE=0>
Response.Write <PARAM NAME=NOLABELS VALUE=0>
Response.Write <PARAM NAME=SRC VALUE=strUrl>
Response.Write <PARAM NAME=CONTROLS VALUE=ImageWindow>
Response.Write <PARAM NAME=CONSOLE VALUE=Clip>
Response.Write <PARAM NAME=LOOP VALUE=0>
Response.Write <PARAM NAME=NUMLOOP VALUE=0>
Response.Write <PARAM NAME=CENTER VALUE=0>
Response.Write <PARAM NAME=MAINTAINASPECT VALUE=0>
Response.Write <PARAM NAME=BACKGROUNDCOLOR VALUE=#000000>
Response.Write </OBJECT>
Response.Write <BR>
Response.Write <OBJECT height=32 width=strWidth classid=clsid:CFCDAA03-8BE4-11cf-B84B-0020AFBBCCFA>
Response.Write <PARAM NAME=_ExtentX VALUE=12700>
Response.Write <PARAM NAME=_ExtentY VALUE=847>
Response.Write <PARAM NAME=AUTOSTART VALUE=0>
Response.Write <PARAM NAME=SHUFFLE VALUE=0>
Response.Write <PARAM NAME=PREFETCH VALUE=0>
Response.Write <PARAM NAME=NOLABELS VALUE=0>
Response.Write <PARAM NAME=CONTROLS VALUE=ControlPanel,StatusBar>
Response.Write <PARAM NAME=CONSOLE VALUE=Clip>
Response.Write <PARAM NAME=LOOP VALUE=0>
Response.Write <PARAM NAME=NUMLOOP VALUE=0>
Response.Write <PARAM NAME=CENTER VALUE=0>
Response.Write <PARAM NAME=MAINTAINASPECT VALUE=0>
Response.Write <PARAM NAME=BACKGROUNDCOLOR VALUE=#000000>
Response.Write </OBJECT>
End Select
End If
End Sub

　　调用方式:

Call SelPlay(DvUrl,280,220)
