(function(){ 
QQMenuInt=_QQMenuInt; 
moveQQmenu=_moveQQmenu; 
function _QQMenuInt(){ 
QQMenu.style.position="absolute"; 
QQMenu.style.display=""; 
if(parseInt(document.documentElement.offsetWidth)>1024){ 
QQMenuPosition.Left+=(parseInt(document.documentElement.offsetWidth)-1024-20); 
} 
if(QQMenuPosition.isRight){ 
QQMenu.style.right=QQMenuPosition.Left+"px"; 
}else{ 
QQMenu.style.left=QQMenuPosition.Left+"px"; 
} 
QQMenu.style.top=QQMenuPosition.Top+"px"; 
moveQQmenu(); 
} 
function _moveQQmenu(){ 
var from=parseInt(QQMenu.style.top,10); 
var yOffset; 
var to=window.pageYOffset?window.pageYOffset:document.documentElement.scrollTop; 
to=to+QQMenuPosition.Top; 
if(to!=from){ 
yOffset = Math.ceil(Math.abs(to-from)/20); 
if(tovar oldTop=parseInt(QQMenu.style.top,10); 
QQMenu.style.top=(oldTop+yOffset)+"px"; 
} 
if(QQMenu.style.display!="none"){ 
window.setTimeout("moveQQmenu()",QQMenuPosition.timeout); 
} 
} 
})() 

使用方法：
1、引入上面的js
2、在页面的最后面加上

复制代码代码如下:

QQMenu为漂浮层的最外层ID
QQMenuPosition是设置漂浮层相关参数
Left:层相对于左侧的偏移量。如果isRight为true则是相对于右侧的偏移量
Top:层相对于顶部的偏移量
timeout:层移动时间间隔，越大越慢
