前面我们讲解了一个网页百叶窗切换动画效果，不过是横向百叶窗，这个是竖向百叶窗，代码基本一样：
复制代码 代码如下:
<html>
<head>
<title>百叶窗页面切换效果</title>
<style>
<!--
.intro{
position:absolute;
left:0;
top:0;
layer-background-color:green;
background-color:green;
border:0.1px solid green
}
-->
</style>
</head>
<body>
<div></div><div></div><div
></div><div></div><div></div><div
></div><div></div><div></div>
<script language="JavaScript1.2">
var speed=20
var temp=new Array()
var temp2=new Array()
if (document.layers){
for (i=1;i<=8;i++){
temp[i]=eval("document.i"+i+".clip")
temp2[i]=eval("document.i"+i)
temp[i].width=window.innerWidth/8-0.3
temp[i].height=window.innerHeight
temp2[i].left=(i-1)*temp[i].width
}
}
else if (document.all){
var clipbottom=document.body.offsetHeight,cliptop=0
for (i=1;i<=8;i++){
temp[i]=eval("document.all.i"+i+".style")
temp[i].width=document.body.clientWidth/8
temp[i].height=document.body.offsetHeight
temp[i].left=(i-1)*parseInt(temp[i].width)
}
}
function openit(){
window.scrollTo(0,0)
if (document.layers){
for (i=1;i<=8;i=i+2)
temp[i].bottom-=speed
for (i=2;i<=8;i=i+2)
temp[i].top+=speed
if (temp[2].top>window.innerHeight)
clearInterval(stopit)
}
else if (document.all){
clipbottom-=speed
for (i=1;i<=8;i=i+2){
temp[i].clip="rect(0 auto+"+clipbottom+" 0)"
}
cliptop+=speed
for (i=2;i<=8;i=i+2){
temp[i].clip="rect("+cliptop+" auto auto)"
}
if (clipbottom<=0)
clearInterval(stopit)
}
}
function gogo(){
stopit=setInterval("openit()",100)
}
gogo()
</script>
</body>
