Javascript技術實現真正的網上試聽

來源:互聯網
上載者:User
javascript 該指令碼的特點:應用Javascript的層技術,和一些function()使播放音樂的同時實現歌詞的相應滾動。
使用realplay的rm格式音樂使下載的同時進行播放。
(該特殊效果對IE4以上都有效。)

示範:
<html>
<head>
<SCRIPT Language="Javascript1.2">
<!--
var locate = 0;
var scro = 0;
var go=80;//控制滾動的速度,越小越快。
//以下函數實現滾動
function scroller() {
if ( scro==1 ){
locate++;
scroll(20,locate);
clearTimeout(timer);
var timer = setTimeout("scroller()",go);
timer;
}
else{

scroll(20,locate);
}
}
//-->
</SCRIPT>

<SCRIPT Language="Javascript1.2">
<!--
var offsettop=20//定義層的相應位置

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>
