利用JAVASCRIPT控制MEDIA PLAYER的功能实现

<script language=javascript defer>
var volv=phx.settings.volume;
setinterval("if(phx.playstate==3){time.innertext=phx.controls.currentpositionstring+\'|\'+
phx.currentmedia.durationstring}",1000);
setinterval("if(phx.playstate==3){itcn.style.width=parseint(245*(phx.controls.currentposition/phx.currentmedia.duration))}",1000);
function volup(){
if (volv<100){
volv+=5;
phx.settings.volume=volv;
time.innertext=volv;}
else{time.innertext=\'最大\';}
}
function voldown(){
if (volv>0){
volv-=5;
phx.settings.volume=volv;
time.innertext=volv;}
else{time.innertext=\'最小\';}
}
</script>
