视频播放的实现

 

< object  width ="320"  height ="250"  classid ="clsid:CFCDAA03-8BE4-11cf-B84B-0020AFBBCCFA" >

< param  name ="CONTROLS"  value ="ImageWindow" >

< param  name ="CONSOLE"  value ="Video" >

< param  name ="CENTER"  value ="TRUE" >

< param  name ="MAINTAINSPECT"  value ="TRUE" >

</ object >  //定义播放界面
< object  width ="320"  height ="30"  classid ="clsid:CFCDAA03-8BE4-11cf-B84B-0020AFBBCCFA" >

< param  name ="CONTROLS"  value ="StatusBar" >

< param  name ="CONSOLE"  value ="Video" >

</ object >  //定义状态栏

< object  width ="320"  height ="30"  classid ="clsid:CFCDAA03-8BE4-11cf-B84B-0020AFBBCCFA" >

< param  name ="CONTROLS"  value ="ControlPanel" >

< param  name ="CONSOLE"  value ="Video" >

< param  name ="SRC"  value ="<?php echo getsrc(); ?>" >

< param  name ="AUTOSTART"  value ="TRUE" >

< param  name ="PREFETCH"  value ="0" >

< param  name ="LOOP"  value ="0" >

< param  name ="NUMLOOP"  value ="0" >

</ object >  //定义控制面板
通过document.getElementById("Video").src="xxx.rm"来改变播放的视频地址
// 三、检测用户是否安装RealPlayer播放器
//
在页面的<head></head>部分加入以下JavaScript代码,用以检测用户是否安装RealPlayer播放器:

< SCRIPT LANGUAGE = JavaScript >

<!--

var  RealMode = 0 ;

var  RealPlayer5 = 0 ;

var  RealPlayer4 = 0 ;

var  RealPlayerG2 = 0 ;

if  (navigator.userAgent.indexOf( " MSIE " ) <   0  ) {

numPlugins 
= navigator.plugins.length;

for (i = 0; i < numPlugins; i ){

plugin 
= navigator.plugins[i];

if (plugin.name.substring(0,10)=="RealPlayer"){
RealMode
=1;

}


}


}


//  以下代码通过VBScript的CreateObject()函数动态的创建RealPlayer对象

document.write(
' <SCRIPT LANGUAGE=VBScript\> \n ' );

document.write(
' on error resume next \n ' );

document.write(
' RealPlayerG2 = (NOT IsNull(CreateObject("rmocx.RealPlayer G2 Control")))\n ' );

document.write(
' RealPlayer5 = (NOT IsNull(CreateObject("RealPlayer.RealPlayer(tm) ActiveX Control (32-bit)")))\n ' );

document.write(
' RealPlayer4 = (NOT IsNull(CreateObject("RealVideo.RealVideo(tm) ActiveX Control (32-bit)")))\n ' );

document.write(
' </SCRIPT\> \n ' );

if  ( RealPlayerG2  ||  RealPlayer5  ||  RealPlayer4 ) {

//可以在此处添加<object>对象

}
else   if  ( RealMode ) // NetScape浏览器用户

// 可以在此处加入<embed>对象

}
else {
window.location.replace(
"install.htm"); // 转入install.htm页面指导用户进行安装

}
