第二步：
在网页<head>区添加以下样式和js代码
<style type="text/css">
html {
overflow: hidden;
}
body {
background: #222;
width: 100%;
height: 100%;
cursor: crosshair;
}
.spanSlide {
position: absolute;
background: #000;
font-size: 1px;
overflow: hidden;
}
.imgSlide {
position: absolute;
left: 5%;
top: 5%;
width: 90%;
height: 90%;
overflow: hidden;
}
.txtSlide {
position: absolute;
top: 5%;
left: 50px;
width:100%;
color:#FFF;
font-family: arial, helvetica, verdana, sans-serif;
font-weight: bold;
font-size:96px;
letter-spacing:12px;
filter: alpha(opacity=70);
-moz-opacity:0.7;
opacity:0.7;
}
</style>
<script type="text/javascript">

var ym=0;
var ny=0;
createElement = function(container, type, param){
o=document.createElement(type);
for(var i in param)o[i]=param[i];
container.appendChild(o);
return o;
}
mooz = {
O:[],
/////////
mult:6,
nbI:5,
/////////
rwh:0,
imgsrc:0,
W:0,
H:0,
Xoom:function(N){
this.o = createElement(document.getElementById("screen"), "span", {
'className':'spanSlide'
});
img = createElement(this.o, "img", {
'className':"imgSlide",
'src':mooz.imgsrc[N%mooz.imgsrc.length].src
});
spa = createElement(this.o, "span", {
'className':"imgSlide"
});
txt = createElement(spa, "span", {
'className':"txtSlide",
'innerHTML':mooz.imgsrc[N%mooz.imgsrc.length].title
});
this.N = 10000+N;
},
mainloop:function(){
with(this){
for(i=0; i<mooz.nbI; i++) {
O[i].N += (ym-ny)/8000;
N = O[i].N%nbI;
ti = Math.pow(mult,N);
with(O[i].o.style){
left = Math.round((W-(ti*rwh))/(W+ti)*(W*.5))+"px";
top = Math.round((H-ti)/(H+ti)*(H*.5))+"px";
zIndex = Math.round(10000-ti*.1);
width = Math.round(ti*rwh)+"px";
height = Math.round(ti)+"px";
}
}
}
setTimeout("mooz.mainloop();", 16);
},
oigres:function(){
with(this){
W = parseInt(document.getElementById("screen").style.width);
H = parseInt(document.getElementById("screen").style.height);
imgsrc = document.getElementById("images").getElementsByTagName("img");
rwh = imgsrc[0].width/imgsrc[0].height;
for(var i=0;i<nbI;i++) O[i] = new Xoom(i);
mainloop();
}
}
}
document.onmousemove = function(e){
if(window.event) e=window.event;
ym = (e.y || e.clientY);
if(ym/2>ny)ny=ym/2;
}
window.onload = function(){
ym = ny+50;
mooz.oigres();
}
</script>
第三步：
在<body>区添加以下代码
<div style="position:absolute;left:50%;top:50%"> <div style="position:absolute;width:720px;height:560px;left:-360px;top:-280px;background:#fff"></div> <div style="position:absolute;left:-40px;top:-6px;color:#000;font-family:arial;font-size:0.9em">Loading...</div> <div id="screen" style="position:absolute;width:640px;height:480px;left:-320px;top:-240px;overflow:hidden"></div> </div> <div id="images" style="visibility:hidden"> <img title="infinite" src="pil.jpg"> <img title="yellow" src="cit.jpg"> <img title="earth" src="earth.jpg"> <img title="dream" src="draps.jpg"> <img title="flowers" src="flo.jpg"> </div>
