一个首页顶部图片（Flash）自动下拉收缩的广告代码
在HTML页面的<head></head>中加入下面的javascript脚本：
Code<script type="text/javascript">
var ads_time = 500;
var ads_h = 0;
function addCount()
{
if(ads_time>0)
{
ads_time--;
ads_h = ads_h+50;
}
else
{
return;
}
if(ads_h>=330) //高度
{
return;
}
document.getElementById("ads").style.display = "";
document.getElementById("ads").style.height = ads_h+"px";
setTimeout("addCount()",30);
}
window.onload = function showAds()
{
addCount();
setTimeout("noneAds()",8000); //停留时间自己适当调整
}
</script>
<script type="text/javascript">
var ads_T = 500;
var ads_N = 330; //高度。如果高度调整不正确，可能会导致图片无法自动收缩
function noneAds()
{
if(ads_T>0)
{
ads_T--;
ads_N = ads_N-25;
}
else
{
return;
}
if(ads_N<=0)
{
document.getElementById("ads").style.display = "none";
return;
}
document.getElementById("ads").style.height = ads_N+"px";
setTimeout("noneAds()",30);
}
</script>
在<body>中插入下面的HTML代码，以显示图片（或Flash）
Code<!-- 下拉大幅广告 Start -->
<div id="ads" style="margin:auto; display:none; width:100%; top:0px; height:0px; position:relative; overflow:hidden; text-align:center;">
