微博导航看起来很美观，实现起来也不麻烦，直接写代码了
<!DOCTYPE html> <html> <head> <meta charset="utf-8" /> <title></title> <script type="text/javascript"> var hiddenChild = function(obj) { var ul = obj.getElementsByTagName("ul")[0]; ul.style.display = 'none'; } /* *obj表示导航条中的直接li */ var showChild = function(obj) { var ul = obj.getElementsByTagName("ul")[0]; ul.style.display = 'block'; } </script> <style type="text/css"> * { margin: 0px; padding: 0px } /*导航条*/ #nav { line-height: 60px; list-style-type: none; background-color: #0000FF; text-align: center; } #nav a { color: white; text-decoration: none; display: block; width: 80px; font-size: 20px; font-weight: 800; } #nav a:hover { background-color: #ccc; } #nav li { background-color: blue; float: left; color: white; list-style-type: none; } #nav li ul { position: absolute; display: none; width: 130px; } .show { display: block; } </style> </head> <body> <ul id="nav"> <li onmouseover="showChild(this);" onmouseleave="hiddenChild(this);"> <a href="#">首页</a> <ul> <li> <a href="#">全部广播</a> </li> <li> <a href="#">好友</a> </li> <li> <a href="#">关注</a> </li> </ul> </li> <li onmouseover="showChild(this);" onmouseleave="hiddenChild(this);"> <a href="#">微频道</a> <ul> <li> <a href="#">微频道1</a> </li> <li> <a href="#">微频道2</a> </li> </ul> </li> <li onmouseover="showChild(this);" onmouseleave="hiddenChild(this);"> <a href="#">找人</a> <ul> <li> <a href="#">明星</a> </li> <li> <a href="#">达人</a> </li> </ul> </li> <li onmouseover="showChild(this);" onmouseleave="hiddenChild(this);"> <a href="#">微群</a> <ul> <li> <a href="#">股票</a> </li> </ul> </li> </ul> </body> </html>
以上代码就是用js实现微博导航栏，需要的朋友可以来参考下。
