整个页面的移动图片

下面为效果显示

脚本说明:
第一步：把如下代码加入<body>区域中
<SCRIPT language=JavaScript><!--
var ver = 3
bVer = parseInt(navigator.appVersion);
if(bVer >= 4)  ver = 4

var ns = navigator.appName == "Netscape";
var ie = navigator.appName == "MSIE";

//////////// ticker variables ////////////////////////////////////////

var pix = 1;           // number of pixels to move per frame
var rate = 70;         // frames per second
var ImgWidth = 1200;   // width of ticker image

/////////////////////////////////////////////////////////////////////

var time = 1000/rate;
var again = - ImgWidth

function tick() {

if (ver ==3) return

if (ns){
        document.Layer1.offset(-pix,0);

document.Layer2.offset(-pix,0);

if (document.Layer1.left <= again) document.Layer1.left = ImgWidth;

if (document.Layer2.left <= again) document.Layer2.left = ImgWidth;
        }
else {
        newpix = document.all["Layer1"].style.pixelLeft - pix;
        newpix2 = document.all["Layer2"].style.pixelLeft - pix;

document.all["Layer1"].style.pixelLeft = newpix;

document.all["Layer2"].style.pixelLeft = newpix2;

if (document.all["Layer1"].style.pixelLeft <= again) document.all["Layer1"].style.pixelLeft = ImgWidth;

if (document.all["Layer2"].style.pixelLeft <= again) document.all["Layer2"].style.pixelLeft = ImgWidth;
        }

setTimeout('tick()', time);
}

//-->

</SCRIPT>
<SPAN id=Layer1

style="Z-INDEX: 2; LEFT: 0px; WIDTH: 1200px; POSITION: absolute; TOP: 0px; HEIGHT: 100px"><IMG

height=100 src="scroll.gif" width=1200 border=0> </SPAN><SPAN

id=Layer2

style="Z-INDEX: 1; LEFT: 1200px; WIDTH: 1200px; POSITION: absolute; TOP: 0px; HEIGHT: 100px"><IMG

height=100 src="scroll.gif" width=1200 border=0>

</SPAN>

第二步：把<body>中的内容改为：
<body onload=tick()>
