实现代码一、

<!--***********开始*************-->
<script type="text/javascript">
//<![CDATA[
var tips; var theTop = 200/*这是默认高度,越大越往下*/; var old = theTop;
function initFloatTips() {
tips = document.getElementById('floatTips');
moveTips();
};
function moveTips() {
var tt = 50;
if (window.innerHeight) {
pos = window.pageYOffset
}
else if (document.documentElement && document.documentElement.scrollTop) {
pos = document.documentElement.scrollTop
}
else if (document.body) {
pos = document.body.scrollTop;
}
pos = pos - tips.offsetTop + theTop;
pos = tips.offsetTop + pos / 10;
if (pos < theTop) pos = theTop;
if (pos != old) {
tips.style.top = pos + "px";
tt = 10;
}
old = pos;
setTimeout(moveTips, tt);
}
//!]]>
</script>
<style type="text/css">
.floatTips
{
position: absolute;
border: solid 1px #777;
padding: 3px;
top: 250px;
right: 5px;
width: 30px;
height: 300px;
background: #cccccc;
color: white;
}
.showDiv
{
position: absolute;
border: solid 1px #777;
padding: 3px;
top: 250px;
right: 5px;
width: 300px;
height: 300px;
background: #cccccc;
color: white;
}
</style>
<script type="text/javascript">
function FunOnmouseUp() {
var objFloatTips = $("floatTips");
var objActivityContext = $("activityContext");
objFloatTips.className = "showDiv";
objActivityContext.style.display = "";
}
function FunMouseOut() {
var objFloatTips = $("floatTips");
var objActivityContext = $("activityContext");
objFloatTips.className = "floatTips";
objActivityContext.style.display = "none";
}
function $(objID) {
return document.getElementById(objID);
}
</script>
</head>
<body onload="initFloatTips()">
<div id="floatTips" onmouseover="FunOnmouseUp()" onmouseout="FunMouseOut()" class="floatTips">
最新的活动
<div id="activityContext" style="display: none">
显示最新的活动
</div>
</div>
<!--**********结束***************-->
<table width="100%" border="0" cellpadding="0" cellspacing="0" bgcolor="#F7F7F7">
<tr>
<td height="2101">
</td>
</tr>
</table>
</body>
</html>
如果有时间的话 会稍作美化 然后加上动画效果 应该就能算是个不错的浮动隐藏层了。
方法二、
一、把以下代码插入
标签中：
<div id="FloatDIV" style="position: absolute;top: 0px; border-right: activeborder 1px solid; border-top: activeborder 1px solid; border-left: activeborder 1px solid; border-bottom: activeborder 1px solid;">
浮动层示例：<br />
<a target="_blank" href="tencent://message/?uin=101535223&Site=http://www.jb51.net&Menu=yes"><img border="0" src="http://wpa.qq.com/pa?p=1:101535223:3" alt="有事您说话"></a>
</div>
二、把以下代码插到
