基于vue.js实现侧边菜单栏

<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="/UploadFiles/2021-04-02/jquery.min.js">

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();
  }
 });
});
