javascript技术实现真正的网上试听


答案：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： 
<html> 
<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); 
} 
} 
//--> 
</SCRIPT> 
<meta http-equiv="Content-Type" content="text/html; charset=gb2312">

</head> 
<body bgcolor="#EEEEEE" > 
<SCRIPT Language="javascript1.2"> 
<!-- 
var offsettop=20//定义层的相应位置 

//定义随网页自动滚动的层函数 
function makeStatic() { 
object1.style.pixelTop=document.body.scrollTop+offsettop;object2.style.pixelTop=document.body.scrollTop+offsettop; 
setTimeout("makeStatic()",100);//'100'控制滚动的速度，越小越快。 
} 
//切换‘滚动‘和‘暂停'图像的函数 
function scrorstp() { 
if (scro==1) 
{scro=0; 
object2.style.visibility="visible"; 
object1.style.visibility="visible"; 
} 
else { 
scro=1; 
object1.style.visibility="hidden"; 
scroller();} 
} 
//定义播放的歌曲地址 
document.write('<div id="object2" style="position:absolute; left:20px; top:35px; width:46px; height:16px;cursor:hand; z-index:1 "><img src=http://old.zzzyk.com/article/Article/"zanting.gif" width="45" height="16" onclick=scrorstp()><font size="2"><embed height="20" src="Afainst All Odds Mariah Carey.rm" type="audio/x-pn-realaudio-plugin" width="45" controls="PlayButton" autostart="false"></font></div>') 
//定义‘滚动‘和‘暂停'的切换图像，onclick激发切换。 
document.write('<div id="object1" style="position:absolute; left:20px; top:35px; width:46px; height:16px; cursor:hand; z-index:1 "><img src=http://old.zzzyk.com/article/Article/"gundong.gif" width="45" height="16" onclick=scrorstp()></div>') 
//启动javascript 
function menu3(){ 
if (document.all||document.layers) 
makeStatic() 
} 
window.onload=menu3

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> 
You're 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 we've shared the laughter and the pain <br> 
And even shared the tears <br> 
You're the only one <br> 
Who really knew me at all <br><br> 
So take a look at me now <br> 
Oh there's just an empty space <br> 
And there's nothing left here to remind me <br> 
Just the memory of your face <br> 
Take a look at me now <br> 
'Cause there's just an empty space <br> 
And you coming back to me is against all odds <br> 
And that's what I've got to face <br><br> 
I wish I could just make you turn around <br> 
Turn around and see me cry <br> 
There's so much I need to say to you <br> 
So many reasons why <br> 
You're the only one <br> 
Who really knew me at all <br><br> 
So take a look at me now <br> 
'Cause there's just an empty space <br> 
And there's nothing left here to remind me <br> 
Just the memory of your face <br> 
Take a look at me now <br> 
'Cause there's just an empty space <br> 
But to wait for you is <br> 
All I can do <br> 
And that's what I've got to face <br> 
Take a good look at me now <br> 
'Cause l'll still be standing here <br> 
And you coming back to me is against all odds <br> 
That's the chance I've qot to take <br><br> 
Take a look at me now </p>
