Javascript技术实现真正的网上试听|中文方案文档站(提供各类方案下载,WORD文档下载,范文,案例等)

　　该脚本的特点：应用javascript的层技术和一些函数，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">
<title>welcome to yi's home</title></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="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="gundong.gif" width="45" height="16" onclick=scrorstp()></div>');
function menu3(){
if (document.all||document.layers)
makestatic();
}
window.onload=menu3;
</script>以下是歌词部分
<ul>
<li>
<div align="center">

<p style="line-height: 150%" align="justify" class="font"><span class="font">
how can i just let you walk away

just let you leave without a trace

when i stand here taking

every breath with you

you're the only one

who really knew me at all

how can you just walk away from me

when all i can do is watch you leave

'cause we've shared the laughter and the pain

and even shared the tears

you're the only one

who really knew me at all

so take a look at me now

oh there's just an empty space

and there's nothing left here to remind me

just the memory of your face

take a look at me now

'cause there's just an empty space

and you coming back to me is against all odds

and that's what i've got to face

i wish i could just make you turn around

turn around and see me cry

there's so much i need to say to you

so many reasons why

you're the only one

who really knew me at all

so take a look at me now

'cause there's just an empty space

and there's nothing left here to remind me

just the memory of your face

take a look at me now

'cause there's just an empty space

but to wait for you is

all i can do

and that's what i've got to face

take a good look at me now

'cause l'll still be standing here

and you coming back to me is against all odds

that's the chance i've qot to take

take a look at me now </p>
