下拉式的页面初始化

下拉式的页面初始化

其实网页的初始化方式有很多种。
以下的例子就介绍了页面初始化的一种形式：

<html>
<head>
<title>Example</title>
<meta http-equiv="Content-Type" content="text/html; charset=gb2312">
<style type="text/css">

</style>
<script>
var done=0;
var curscr=0;
var speed=1;
function ol()
{
divmove.style.top=document.body.scrollHeight;
divmove.style.height=document.body.clientHeight;
setTimeout(ol2,1);
}
function ol2()
{
varscr=document.body.scrollHeight;
document.body.scrollTop=varscr;
adjWnd();
}
function adjWnd()
{
varscr-=speed;
document.body.scrollTop=varscr;
if(varscr<1)
{
done=1;
divmove.style.top=0;
divmove.style.visibility="hidden";
}
if(!done)setTimeout("adjWnd();",1);
}
</script>
</head>
<body bgcolor="#FFFFFF" text="#000000" onload="ol();">
<div id="divmove" style="position:absolute; left:-1px; top:282px; width:100%; height:83px; z-index:1; background-color: #FFFFFF; layer-background-color: #FFFFFF; border: 1px none #000000">
<div align="center">
