侧边菜单栏应该是很多项目里必不可少的 自己手写了一个
下面是效果图

下面就说一下实现的过程 还是比较简单的
首先导入一下需要的文件

<link rel="stylesheet" type="text/css" href="bootstrap/css/bootstrap.min.css" rel="external nofollow" ><link rel="stylesheet" type="text/css" href="css/font-awesome.min.css" rel="external nofollow" ><link rel="stylesheet" type="text/css" href="css/nav.css" rel="external nofollow" ><script type="text/javascript" src="js/jquery.min.js"></script><script type="text/javascript" src="bootstrap/js/bootstrap.min.js"></script>

接下来就是我的html

<nav class="sider-bar small-bar"> <ul> <li class="home_btn"> <a href="javascript:;" id="full-bar" > <i class="fa fa-navicon nav_icon"></i> </a> </li> <li> <a href="javascript:;"> <i class="fa fa-home nav_icon"></i> <span class="nav-text">主页</span> </a> </li> <li class="drop-show"> <a href="javascript:;" > <i class="fa fa-cogs nav_icon"></i> <span class="nav-text">系统<i class="fa fa-angle-right nav_icon "></i></span> </a> <ul class="drop-list"> <li><a href="user.html">用户管理</a></li> <li><a href="buttons.html">权限设置</a></li> <li><a href="buttons.html">操作日志</a></li> <li><a href="buttons.html">设备运行日志</a></li> </ul> </li> <li class="drop-show"> <a href="javascript:;"> <i class="fa fa-check-square-o nav_icon"></i> <span class="nav-text">防区 <i class="fa fa-angle-right nav_icon "></i></span> </a> <ul class="drop-list"> <li><a href="buttons.html">防区管理</a></li> </ul> </li> <li class="drop-show"> <a href="javascript:;"> <i class="fa fa-info-circle nav_icon"></i> <span class="nav-text">警报 <i class="fa fa-angle-right nav_icon "></i></span> </a> <ul class="drop-list"> <li><a href="buttons.html">历史报警曲线</a></li> <li><a href="buttons.html">报表统计</a></li> <li><a href="buttons.html">警情处理</a></li> </ul> </li> <li> <a href="#"> <i class="fa fa-dashboard (alias) nav_icon"></i> <span class="nav-text">设备</span> </a> </li> </ul></nav>

然后是css

* { margin: 0; padding: 0;}body { font-family:Microsoft YaHei; font-size:14px;}li,ol,ul { list-style: none;}a { text-decoration: none; outline: 0;}a:hover,a:link{ text-decoration:none;}.sider-bar{ float:left; width:220px; height:100%; z-index:999; overflow:hidden; background:rgba(0,0,0,0.7); }.sider-bar ul{ width:100%; float:left}.sider-bar ul li{ width:100%; float:left; font-size:14px;}.sider-bar ul li a{ padding:8px 10px; display:block; color:#fff; }.sider-bar ul li.home_btn{ background:#282D2D; text-align:center}.sider-bar ul li.home_btn:hover{ background:#282D2D}.sider-bar ul li a:hover{ background:#0099CC;}.sider-bar ul li .nav_icon{ font-size:18px; margin:0 5px;}.small-bar{ width:50px;}.small-bar li { text-align:center;}.small-bar li a{ display:block; text-align:center}.small-bar li span{ display:none}.small-bar ul li .nav_icon{ font-size:24px; margin:0}ul.drop-list{ display:none; margin-left:30px; width:190px;}.fa-angle-right{ float:right}body, html { height:100%;}

最后也就是我的js

$(document).ready(function(){ //展开主菜单 $("#full-bar").click(function(){ $(".sider-bar").toggleClass("small-bar"); if($(".sider-bar").hasClass('small-bar')){ $(".drop-list").slideUp(); } }); $(".drop-show").click(function(){ if(!$(".sider-bar").hasClass('small-bar')){ $(this).children(".drop-list").slideToggle(); $(this).siblings('li').children(".drop-list").slideUp(); } });});
