利用&#106avascript实现对Media Player的控制功能

<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>
