<IMG onclick="media_stop()" height="11" alt="停止播放" src="image/stop_b.gif" border="0"
name="stop"> <IMG title="暂停" onclick="media_pause()" src="image/pause.gif"> <IMG title="静音" onclick="media_Setmute()" src="image/sound.gif">
下面的是控制代码：
<script>
document.NSPlay.Stop();
document.real.setSource(reals);
function media_stop()
{
if(isplaying=true)
{
document.NSPlay.Stop();
}
}
function media_pause()
{
if(isplaying=true)
{
document.NSPlay.Pause();

}
function media_play()
{
document.NSPlay.Play();
 isplaying=true;
}
function media_Setmute()
{
if(isplaying=true)
{
if (document.NSPlay.Mute)
{
document.NSPlay.Mute=false;
}else

document.NSPlay.Mute=true;
