大家看看这个网页，因为声音不好，想控制使它静音，就是让他不发声
谁帮我啊？
我天天问问题，真不好意思，分数就这么多了，统统献上！


[解决办法]
你的网页打不开，我这里有一个realmedia player 的script
function clipMute()///设置静音
var dpv = document.playvideo; /// 获取object对象
dpv.SetMute(true|false) /// 设置是否静音

<script language= "javascript ">
function PlayPause(){
var dpv = document.playvideo;
var pbi = document.all.playpause;
if(dpv!=null&&pbi!=null){
if(dpv.CanPlay())
{
dpv.DoPlay();
pbi.src = "images/playbuttn.gif ";
}
else
{
dpv.DoPause();
pbi.src = "images/pausebuttn.gif ";
}
}
}
function clipStop(){
var dpv = document.playvideo;
if(dpv!=null){
if(dpv.CanStop())
{
dpv.DoStop();
}
}
}
///设置静音
function clipMute(){
var dpv = document.playvideo;
var pbi = document.all.clipmuteImg;
if(dpv!=null&&pbi!=null){
if(dpv.GetMute())
{
dpv.SetMute(false);
pbi.src = "images/volumnbuttn.gif ";
}
else
{
dpv.SetMute(true);
pbi.src = "images/volumnbuttnmuted.gif ";
}
}
}

function clipfullScreen(){
var dpv = document.playvideo;
if(dpv!=null){
dpv.SetFullScreen();
}
}

function clipVolume(vol){
var dpv = document.playvideo;
if(dpv!=null&&vol> =0&&vol <=100){
dpv.SetVolume(vol);
}
}

function goPos(s){
var dpv = document.playvideo;
var clipTime = dpv.GetLength()/1000;
var gotopos = (s/100)*clipTime;
dpv.SetPosition(gotopos*1000);
}
</script>
