网页特效”漂浮广告代码”？找网页右下角广告代码（QQ系统消息样式）

漂浮广告代码 代码如下《div id=“ad“ style=“position:absolute“》《a href=“《img src=“《/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》把上面的代码放在需要放置广告的页面HTML代码的《body》《/body》之间-----上面的代码说明-------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为真是层向右移动，否则向左；yin为真是层向下移动，否则向上 var step = 1 //层移动的步长，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，值越小移动速度越快
