页面产生百叶窗

页面产生百叶窗脚本

效果一目了然吧!

脚本说明:

第一步:把如下代码加入<head>区域中

<style>

<!--

.intro{position:absolute;

left:0;

top:0;

layer-background-color:green;

background-color:green;

border:0.1px solid green

}

-->

</style>

第二步:把如下代码加入<body>区域中

<div id="i1" class="intro"></div><div id="i2" class="intro"></div><div id="i3"

class="intro"></div><div id="i4" class="intro"></div><div id="i5" class="intro"></div><div

id="i6" class="intro"></div><div id="i7" class="intro"></div><div id="i8" class="intro"></div>

<!--

var speed=30

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)

}
