菜单导航—改变宽度

1、使用javascript脚本实现：

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<title>导航菜单</title>
<style type="text/css"> * { margin: 0; padding: 0; font-size: 14px; } a { color: #333; text-decoration: none } ul { list-style: none; height: 30px; border-bottom: 5px solid #F60; margin-top: 20px; padding-left: 50px; } ul li { float: left } ul li a { display: block; height: 30px; text-align: center; line-height: 30px; width:120px; background: #efefef; margin-left: 1px; } a.on, a:hover { background: #F60; color: #fff; } </style>
<script> window.onload=function() { var as = document.getElementsByTagName("a"); for(var i=0; i<as.length; i++) { as[i].onmouseover=function() { var this1 = this; clearInterval(si); var si = setInterval ( function() { this1.style.width = this1.offsetWidth+10+"px"; if(this1.offsetWidth>160) { clearInterval(si); } },30); } as[i].onmouseout = function() { var this2 = this; clearInterval(si); var si = setInterval ( function() { this2.style.width=this2.offsetWidth-10+"px"; if(this2.offsetWidth<120) { clearInterval(si); } },30); } } } </script>
</head>
<body>
<ul>
    <li><a class="on" href="#">首　　页</a></li>
    <li><a href="#">新闻快讯</a></li>
    <li><a href="#">产品展示</a></li>
    <li><a href="#">售后服务</a></li>
    <li><a href="#">联系我们</a></li>
</ul>
</body>
</html>
