该脚本的特点:应用javascript的层技术，和一些function（）使播放音乐的同时实现歌词的相应滚动。
使用realplay的rm格式音乐使下载的同时进行播放。
（该特殊效果对ie4以上都有效。）
演示：

<head>
<script language="javascript1.2">

var locate = 0;
var scro = 0;
var go=80;//控制滚动的速度，越小越快。
//以下函数实现滚动
function scroller() {
if ( scro==1 ){
locate++;
scroll(20,locate);
cleartimeout(timer);
var timer = settimeout("scroller()",go);
timer;
}
else{
scroll(20,locate);

how can i just let you walk away <br>
just let you leave without a trace <br>
when i stand here taking <br>
every breath with you <br>
youre the only one <br>
who really knew me at all <br>
how can you just walk away from me <br>
when all i can do is watch you leave <br>
cause weve shared the laughter and the pain <br>
and even shared the tears <br>
youre the only one <br>
who really knew me at all <br><br>
so take a look at me now <br>
oh theres just an empty space <br>
and theres nothing left here to remind me <br>
just the memory of your face <br>
take a look at me now <br>
cause theres just an empty space <br>
and you coming back to me is against all odds <br>
and thats what ive got to face <br><br>
i wish i could just make you turn around <br>
turn around and see me cry <br>
theres so much i need to say to you <br>
so many reasons why <br>
youre the only one <br>
who really knew me at all <br><br>
so take a look at me now <br>
cause theres just an empty space <br>
and theres nothing left here to remind me <br>
just the memory of your face <br>
take a look at me now <br>
cause theres just an empty space <br>
but to wait for you is <br>
all i can do <br>
and thats what ive got to face <br>
take a good look at me now <br>
cause lll still be standing here <br>
and you coming back to me is against all odds <br>
thats the chance ive qot to take <br><br>
take a look at me now </p>
