1、将存为menu.htm格式文件以下为代码内容：
复制代码 代码如下:
<html>
<head>
<style>
.menuskin{
BORDER-RIGHT:#CBD7E91pxsolid;BORDER-TOP:#CBD7E91pxsolid;BACKGROUND-IMAGE:url(image/menubg.gif);VISIBILITY:hidden;FONT:12pxTahoma,Verdana;BORDER-LEFT:#CBD7E91pxsolid;BORDER-BOTTOM:#CBD7E91pxsolid;POSITION:absolute;BACKGROUND-COLOR:#ffffff
}
.menuskinA{
PADDING-RIGHT:10px;PADDING-LEFT:25px;COLOR:#3A4273;TEXT-DECORATION:none
}
#mouseoverstyle{
BORDER-RIGHT:#597db51pxsolid;PADDING-RIGHT:0px;BORDER-TOP:#597db51pxsolid;PADDING-LEFT:0px;PADDING-BOTTOM:0px;MARGIN:2px;BORDER-LEFT:#597db51pxsolid;PADDING-TOP:0px;BORDER-BOTTOM:#597db51pxsolid;BACKGROUND-COLOR:#c9d5e7
}
#mouseoverstyleA{
COLOR:black
}
.menuitems{
PADDING-RIGHT:1px;PADDING-LEFT:1px;PADDING-BOTTOM:1px;MARGIN:2px;WORD-BREAK:keep-all;PADDING-TOP:1px
}
</style>
<scripttype="text/javascript"src="menu.js"></script>
</head>
<bodyvlink='#333333'link='#333333'>
<divclass=menuskinid=popmenuonmouseover="clearhidemenu();highlightmenu(event,'on')"onmouseout="highlightmenu(event,'off');dynamichide(event)"style="Z-index:100"></div>
<center>
<ahref="###"onMouseOver="showmenu(event,'<divclass=menuitems><ahref=http://www.gyct.cn/article/index.asp>网络文摘</a></div><divclass=menuitems><ahref=http://www.gyct.cn/article/index.asp>网络文摘</a></div>')">思客秀</a>
</center>
</body>
</html>
2、将下面代码存为menu.js文件，并与menu.htm放到同级目录下
复制代码 代码如下:
//Pop-itmenu-ByDynamicDrive-ModifiedbyWbird

{

}
returnvBobjects[idname];
}
//showmenuvmenu:内容，允许为空,vmenuobjDIV数据ID，MOD0=关闭浏览器自适应，用于版面导航菜单

}
}
if(!which)
{
return
}
clearhidemenu();
ie_clearshadow();
menuobj=ie4?document.all.popmenu:ns6?document.getElementById("popmenu"):ns4?document.popmenu:""
menuobj.thestyle=(ie4||ns6)?menuobj.style:menuobj

}else{

}
menuobj.thestyle.left=getlength+'px'
if(bottomedge<menuobj.contentheight&&mod!=0){
getlength=ie4?document.body.scrollTop+eventY-menuobj.contentheight-event.offsetY+menuOffY-23:ns6?window.pageYOffset+eventY-menuobj.contentheight-10:eventY-menuobj.contentheight

ie_dropshadow(menuobj,"#999999",3)
returnfalse
}
functionie_y(e){

}
returnl;
}
functionie_dropshadow(el,color,size)
{
vari;
for(i=size;i>0;i--)
{
varrect=document.createElement('div');
varrs=rect.style
rs.position='absolute';
rs.left=(el.style.posLeft+i)+'px';
rs.top=(el.style.posTop+i)+'px';

}
}
functionie_clearshadow()

for(vari=0;i<fo_shadows.length;i++)
{
if(fo_shadows[i])
fo_shadows[i].style.display="none"
}
fo_shadows=newArray();
}
functioncontains_ns6(a,b){

if((b=b.parentNode)==a)
returntrue;
returnfalse;
}
functionhidemenu(){
if(window.menuobj)
menuobj.thestyle.visibility=(ie4||ns6)?"hidden":"hide"
ie_clearshadow()
}
functiondynamichide(e){
if(ie4&&!menuobj.contains(e.toElement))
hidemenu()
elseif(ns6&&e.currentTarget!=e.relatedTarget&&!contains_ns6(e.currentTarget,e.relatedTarget))
hidemenu()
}
functiondelayhidemenu(){
if(ie4||ns6||ns4)
delayhide=setTimeout("hidemenu()",500)
}
functionclearhidemenu(){
if(window.delayhide)
clearTimeout(delayhide)
}
functionhighlightmenu(e,state){
if(document.all)
source_el=event.srcElement
elseif(document.getElementById)
source_el=e.target
if(source_el.className=="menuitems"){
source_el.id=(state=="on")?"mouseoverstyle":""
}
else{
while(source_el.id!="popmenu"){
source_el=document.getElementById?source_el.parentNode:source_el.parentElement
if(source_el.className=="menuitems"){
source_el.id=(state=="on")?"mouseoverstyle":""
}
}
}
}
if(ie4||ns6)
document.onclick=hidemenu
3、在menu.htm目录下建立image目录，制作背景图片
PS:事例效果:
以下为代码内容：
<divclass=menuskinid=popmenuonmouseover=clearhidemenu()onmouseout=dynamichide(event)style="z-index:100;"></div>
<fontcolor="#eeeeee"><ahref=###onMouseOver="showmenu(event,'<divclass=menuitemsid=site_menu><ahref=/common/skins.asp?action=skin_1>简约时尚</a><br/><ahref=/common/skins.asp?action=skin_2>魔兽世界</a><br/><ahref=/common/skins.asp?action=cookies_clearalt=清除您在本站所留的Cookies信息>清除记录</a><br/></div>','site_menu')"><fontcolor=#eeeeee>[选择皮肤]</font></a></font>
