鱼给大家来提供下图片漂浮代码，用于html网页的！线在很多网站都有这样的漂浮图片，多用于广告，这也是为了引人注目罢了，下面给大家提供下面网页图片漂浮的源代码吧！把下面的代码复制到运行框里面看看效果就可以了！下面一共有两种漂浮的可供大家参考
第一种，这个漂浮图片代码不是很常用的！
<script language="JavaScript">
pics=new Array('http://www.bishe.net/themes/tugor/STYLE/IMAGE/MID/mid-little11.jpg','http://www.bishe.net/themes/tugor/STYLE/IMAGE/MID/mid-little12.jpg','http://www.bishe.net/themes/tugor/STYLE/IMAGE/MID/mid-little14.jpg','http://www.bishe.net/themes/tugor/STYLE/IMAGE/MID/mid-little13.jpg')
load=new Array();
function PreLoad(){
for(i=0; i < pics.length; i++)
{
load[i]=new Image();
load[i].src=pics[i];
}
}
PreLoad();

</script>
第二种 这个是常见的代码
<div id="ad" style="position:absolute">
<a href="http://www.bishe.net/" target="_blank">
<img src="http://www.bishe.net/themes/tugor/STYLE/IMAGE/MID/mid-little13.jpg" border="0">
</a></div>
<script>
var x = 50,y = 60
var xin = true, yin = true
var step = 1
var delay = 10
var obj=document.getElementById("ad")
function floatAD() {
var L=T=0
var R= document.body.clientWidth-obj.offsetWidth
var B = document.body.clientHeight-obj.offsetHeight
obj.style.left = x + document.body.scrollLeft
obj.style.top = y + document.body.scrollTop
x = x + step*(xin?1:-1)
if (x < L) { xin = true; x = L}
if (x > R){ xin = false; x = R}
y = y + step*(yin?1:-1)
if (y < T) { yin = true; y = T }
if (y > B) { yin = false; y = B }
}
var itl= setInterval("floatAD()", delay)
obj.onmouseover=function(){clearInterval(itl)}
obj.onmouseout=function(){itl=setInterval("floatAD()", delay)}
</script>
上面的代码插入网页的<body></body>之间
http://www.bishe.net换成是漂浮图片点击后出现的页面，也就是加链接的图片啦
http://www.bishe.net/themes/tugor/STYLE/IMAGE/MID/mid-little13.jpg换成你的漂浮广告图片的URL地址
var x = 50,y = 60 浮动层的初始位置，分别对应层的初始X坐标和Y坐标
var xin = true, yin = true 判断层的X坐标和Y坐标是否在在控制范围之内，xin表示帧是层向右移动，否则向左；yin表示帧是层向下移动，否则向上
var step = 1 移动的速度，值越大移动速度越快
var delay = 10 层移动的时间间隔,单位为毫秒，值越大移动速度越慢
