一款CSS垂直下拉导航栏CSS
演示：
首先是CSS样式：
<style type="text/css">
<!--
body {
font-family: arial, "宋体", serif;
font-size:12px;
}
#nav *{margin:0;padding:0;border:0;}
#nav {
line-height: 34px;
list-style-type: none;
background-color: #999999;
}
#nav a {
display: block; width: 100px; text-align:center;
}
#nav a:link {
color:#666; text-decoration:none;
}
#nav a:visited {
color:#666;text-decoration:none;
}
#nav a:hover {
color:#FFF;text-decoration:none;font-weight:bold;
}
#nav li {
float: left; width: 100px; background:#CCC;
}
#nav li a:hover{
background:#999;
}
#nav li ul {
line-height: 27px; list-style-type: none;text-align:left;
left: -999em; width: 100px; position: absolute;
}
#nav li ul li{
float: left; width: 100px;
background: #F6F6F6;
}
#nav li ul a{ wedisplay: block; width: 76px;text-align:left;padding-left:24px;
}
#nav li ul a:link {
color:#666; text-decoration:none;
}
#nav li ul a:visited {
color:#666;text-decoration:none;
}
#nav li ul a:hover {
color:#F3F3F3;text-decoration:none;font-weight:normal;
background:#C00;
}
#nav li:hover ul {
left: auto;
}
#nav li.sfhover ul {
left: auto;
}
#content {
clear: left;
}
-->
</style>
其次是脚本：
<script type=text/javascript>
function menuFix() {
var sfEls = document.getElementById("nav").getElementsByTagName("li");
for (var i=0; i<sfEls.length; i++) {
sfEls[i].onmouseover=function() {
this.className+=(this.className.length>0? " ": "") + "sfhover";
}
sfEls[i].onMouseDown=function() {
this.className+=(this.className.length>0? " ": "") + "sfhover";
}
sfEls[i].onMouseUp=function() {
this.className+=(this.className.length>0? " ": "") + "sfhover";
}
sfEls[i].onmouseout=function() {
this.className=this.className.replace(new RegExp("( ?|^)sfhover\\b"),
"");
}
}
}
window.onload=menuFix;
</script>
最后是调用：
<ul id="nav">
<li><a href="index.asp">网站首页</a></li>
<li><A href="cxabout.asp" target=_self>关于诚迅</A>
<ul>
<li><A href="cxabout.asp" target=_self>关于诚迅</A></li>
