侧边导航

在很多网页项目中，我们常常会用到侧边导航。那么带图标的侧边导航又是怎么制作的呢？来看看个人写的侧边二级导航吧！

 <div class="box">
        <ul class="sidebar">
            <li class="myResume">
                <span>
                    <em class="icon-man02"></em>
                    <a>我的简历</a>
                    <em class="icon-up"></em>
                </span>
                <ul class="board none">
                    <li class="cur"><a href="">微简历</a></li>
                    <li><a href="">附件简历</a></li>
                </ul>
            </li>
             <li class="myArticle">
                <span>
                    <em class="icon01 icon-article"></em>
                    <a>我的文章</a>
                    <em class="icon02 icon-down"></em>
                </span>
                <ul class="board none">
                    <li><a href="">发布新文章</a></li>
                    <li><a href="">已发布文章</a></li>
                    <li><a href="">未发布文章</a></li>
                </ul>
            </li>
            <li class="myVideo">
                <span>
                    <em class="icon-video"></em>
                    <a>我的视频</a>
                    <em class="icon-down"></em>
                </span>
                <ul class="board none">
                    <li><a href="">我的视频</a></li>
                </ul>
            </li>
             <li class="myInfo">
                <span>
                <em class="icon-writer"></em>
                <a href="">作者信息</a>
                </span>
            </li>

        </ul>

    </div>

它引入的css

*{
    margin: 0;
    padding: 0;
}
img{
    border:0;
}
ol, ul ,li{list-style: none;}
body{
    font-family:"microsoft yahei";
    font-size: 14px;
}
.box{
    width: 202px;
    height: 500px;
    background: #f5f5f5;
    position: absolute;
    left: 0;
    top: 50px;
    background: #4F5E68;
}
.sidebar li,.sidebar li .board,.sidebar li .board li,.sidebar li .board li a{
    width: 100%;
    cursor: pointer;
}
.sidebar li .none{
    display: none;
}
.sidebar li .block{
   display: block;
}
.sidebar li span{
    width: 100%;
    height: 50px;
    line-height: 50px;
    color: #fff;
    font-size: 16px;
    display: block;
}
.sidebar li span a{
  height: 50px;
  line-height: 50px;
  padding: 0 25px 0 0;
  text-decoration: none;
  color: #fff;
  box-sizing: border-box;
}
.sidebar li .board li{
   height: 40px;
   line-height: 40px;
   text-align: center;
}
.sidebar li .board{
    color: #fff;
}
.sidebar li .board li a{
   color: #fff;
   font-size: 14px;
   text-decoration: none;
}
.sidebar li{
    border-top:1px solid #333E45;
}
.sidebar li.active{
    background: #222A2F;
}
.sidebar li span em{
   width: 24px;
   height: 24px;
   display: inline-block;
   margin-top: 14px;
   float: left;
}
.sidebar li span em.icon-man,.sidebar li span em.icon-article,.sidebar li span em.icon-video,.sidebar li span em.icon-writer,
.sidebar li span em.icon-man02,.sidebar li span em.icon-article02,.sidebar li span em.icon-video02,.sidebar li span em.icon-writer02{
  margin-left: 20px;
  margin-right:20px;
}
.sidebar li span a,.sidebar li span em{
  float: left;
}
.sidebar li span em.icon-man{
    background: url(../img/icon-job.png) no-repeat;
}
.sidebar li span em.icon-article{
    background: url(../img/icon-my.png) no-repeat;
}
.sidebar li span em.icon-video{
    background: url(../img/icon-video.png) no-repeat;
}
.sidebar li span em.icon-writer{
    background: url(../img/icon-writer01.png) no-repeat;
}
.sidebar li .board li.cur{
   background: #2f3545;
}
.sidebar li span em.icon-up{
  background: url(../img/up.png) no-repeat;
}
.sidebar li span em.icon-down{
  background: url(../img/down.png) no-repeat;
}
.sidebar li span em.icon-man02{
    background: url(../img/icon-job02.png) no-repeat;
}
.sidebar li span em.icon-article02{
    background: url(../img/icon-my02.png) no-repeat;
}
.sidebar li span em.icon-video02{
    background: url(../img/icon-video02.png) no-repeat;
}
.sidebar li span em.icon-writer02{
    background: url(../img/icon-writer02.png) no-repeat;
}

还有它的js

$(function(){
        $(‘.sidebar li‘).on(‘click‘,function(){
                var flag = true;
                flag = $(this).hasClass(‘active‘);
                if(flag == true){
                      $(this).children(‘span‘).children(‘em.icon-up‘).removeClass(‘icon-up‘).addClass(‘icon-down‘);
                      $(this).children(‘span‘).children(‘em.icon-man02‘).removeClass(‘icon-man02‘).addClass(‘icon-man‘);
                      $(this).children(‘ul‘).slideUp(500);

                }else{

                    $(‘.sidebar li.myResume span em.icon-up‘).removeClass(‘icon-up‘).addClass(‘icon-down‘);

                    $(this).children(‘span‘).children(‘.icon-down‘).removeClass(‘icon-down‘).addClass(‘icon-up‘);

                    $(this).siblings().children().children(‘.icon-up‘).removeClass(‘icon-up‘).addClass(‘icon-down‘);

                    $(this).children(‘ul‘).slideToggle(500);

                    $(‘.sidebar li.myResume ul‘).removeClass(‘block‘).addClass(‘none‘);

                    $(this).addClass(‘active‘).siblings().removeClass(‘active‘);
                }

        })

        $(‘.sidebar li.myResume .board‘).removeClass(‘none‘).addClass(‘block‘);
        $(‘.sidebar li.myResume‘).addClass(‘active‘);
   })

js文件中引入jquery-3.0.0,然后就大功告成。如果你有更好的建议，欢迎点评。
