如果有一定的JavaScript基础,制作浮动广告还是比较容易的。直接上代码了:
复制代码 代码如下:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<title>无标题文档</title>
<style type="text/css">
*{
margin:0;
padding:0;
}
#csdn
{
width:800px;
margin:0 auto;
}
#ad
{
position:absolute;
right:0px;
top:30px;
z-index:1;
}
#cl
{
position:absolute;
right:0px;
top:30px;
z-index:2;
}
</style>
<script type="text/javascript">
var advInitTop=30;
var closeInitTop=30;
function inix()
{
advInitTop=document.getElementById("ad").style.pixelTop;
closeInitTop=document.getElementById("cl").style.pixelTop;
}
function closeAd()
{
document.getElementById("ad").style.display="none";
document.getElementById("cl").style.display="none";
}
function move()
{
//document.getElementById("ad").style.pixelTop=document.body.scrollTop+advInitTop;
//document.getElementById("cl").style.pixelTop=document.body.scrollTop+closeInitTop;
document.getElementById("ad").style.pixelTop=document.documentElement.scrollTop+advInitTop;
document.getElementById("cl").style.pixelTop=document.documentElement.scrollTop+closeInitTop;
//alert(document.getElementById("ad").style.pixelTop);
window.status=document.documentElement.scrollTop+"/"+document.getElementById("ad").style.pixelTop;
}
window.onscroll=move;
</script>
</head>
<body>
<div id="cl" onclick="closeAd()">
<img src="/UploadFiles/2021-04-02/close.jpg"></div>
<div id="csdn">
<a href="http://www.csdn.net"><img src="/UploadFiles/2021-04-02/xiaojie1.jpg"></div>
<div id="ad">
<a href="http://www.taobao.com"><img src="/UploadFiles/2021-04-02/advpic.gif"></div>
</body>
</html>

要点
上述代码中要用document.documentElement ,不要用老的document.body,否则,不符合w3c标准,看不到浮动效果!
