因?yàn)轫?xiàng)目上有這樣的需求，在網(wǎng)上也查了些東西，之前是想找個(gè)差不多類似的套用一下。后來(lái)發(fā)覺(jué)沒(méi)有合適的，因時(shí)間緊迫就自己動(dòng)手寫(xiě)了一個(gè)簡(jiǎn)單的，示例代碼如下兼容火狐和IE7+

實(shí)現(xiàn)代碼一、

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "

<html>

<head>

<meta http-equiv="Content-Type" content="text/html; charset=gb2312" />

<script type="text/javascript">

//<![CDATA[

var tips; var theTop = 200/*這是默認(rèn)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">

最新的活動(dòng)

<div id="activityContext" style="display: none">

顯示最新的活動(dòng)

</div>

</div>



<table width="100%" border="0" cellpadding="0" cellspacing="0" bgcolor="#F7F7F7">

<tr>

<td height="2101">

</td>

</tr>

</table>

</body>

</html>

如果有時(shí)間的話會(huì)稍作美化然后加上動(dòng)畫(huà)效果應(yīng)該就能算是個(gè)不錯(cuò)的浮動(dòng)隱藏層了。

方法二、

一、把以下代碼插入

標(biāo)簽中：

<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;">

浮動(dòng)層示例：<br />

<a target="_blank" href="tencent://message/?uin=101535223&Site=http://m.survivalescaperooms.com&Menu=yes"><img border="0" src="http://wpa.qq.com/pa?p=1:101535223:3" alt="有事您說(shuō)話"></a>

</div>

二、把以下代碼插到標(biāo)簽之后，設(shè)置MarginLeft、MarginTop、Width、Heigth四個(gè)變量的值

<script language="javascript" type="text/javascript">

var MarginLeft = 30; //浮動(dòng)層離瀏覽器右側(cè)的距離

var MarginTop = 50; //浮動(dòng)層離瀏覽器頂部的距離

var Width = 120; //浮動(dòng)層寬度

var Heigth= 45; //浮動(dòng)層高度

//設(shè)置浮動(dòng)層寬、高

function Set()

{

document.getElementById("FloatDIV").style.width = Width;

document.getElementById("FloatDIV").style.height = Heigth;

}

//實(shí)時(shí)設(shè)置浮動(dòng)層的位置

function Move()

{

document.getElementById("FloatDIV").style.top = document.documentElement.scrollTop + MarginTop;

document.getElementById("FloatDIV").style.left = document.documentElement.clientWidth - Width - MarginLeft;

setTimeout("Move();",100);

}

Set();

Move();

</script>
