怎么用flash用javescript控制页面中的mediaplay

function VolDn()
{ // 增音
var ps = Player.settings;
if(ps.mute == true){ps.mute = false;return;}
else{
if (ps.volume <= 30){ ps.volume =0;}
else{ps.volume = ps.volume - 30;}

}

}

function VolUp()
{ //减音
var ps = Player.settings;
if(ps.mute == true){ps.mute = false;return;}
else{
if (ps.volume >= (100-30)) {ps.volume = 100;}
else { ps.volume = ps.volume + 30;}

}

}
function playerPlay(){
Player.URL="mms://202.95.107.151/pggame">
}

function playerStop(){

在HTML中，在你现有的Javascript基础上添加
var isInternetExplorer = navigator.appName.indexOf("Microsoft") != -1;
// 处理 Flash 影片中的所有 FSCommand 消息
function FlashControl_DoFSCommand(command, args) {
var FlashControl = isInternetExplorer ? document.all.FlashControl : document.FlashControl;
// 代码放在此处。
eval(command)();
}
// Internet Explorer 的挂钩
if (navigator.appName && navigator.appName.indexOf("Microsoft") != -1 && navigator.userAgent.indexOf("Windows") != -1 && navigator.userAgent.indexOf("Windows 3.1") == -1) {
document.write(’’<script language=\"VBscript\"\>\n’’);
document.write(’’On Error Resume Next\n’’);
document.write(’’Sub FlashControl_FSCommand(ByVal command, ByVal args)\n’’);
document.write(’’ Call FlashControl_DoFSCommand(command, args)\n’’);
document.write(’’End Sub\n’’);
document.write(’’</script\>\n’’);
}

Javascript中的这个代码提出去
// Internet Explorer 的挂钩
if (navigator.appName && navigator.appName.indexOf("Microsoft") != -1 && navigator.userAgent.indexOf("Windows") != -1 && navigator.userAgent.indexOf("Windows 3.1") == -1) {
document.write(’’<script language=\"VBscript\"\>\n’’);
document.write(’’On Error Resume Next\n’’);
document.write(’’Sub FlashControl_FSCommand(ByVal command, ByVal args)\n’’);
document.write(’’ Call FlashControl_DoFSCommand(command, args)\n’’);
document.write(’’End Sub\n’’);
document.write(’’</script\>\n’’);
}

为
<script language="VBscript">
On Error Resume Next
Sub FlashControl_FSCommand(ByVal command, ByVal args)
Call FlashControl_DoFSCommand(command, args)
End Sub
</script>
