js代码：需引入 layui.all.js




var $ = layui.jquery,
 element = layui.element(),
 form = layui.form();
var html = '';
//获取菜单
$.ajax({

 data:{},
 success:function(data){
 var navs=data.result;
 $.each(navs,function(i,item){
 html += '<dl>';
 html += '<dt><a href="javascript:;" data-url="'+item.url+'" nav-id="'+item.id+'"><i class="'+item.icon+'"></i><cite>'+item.title+'</cite></a></dt>';
 //如果有第二级菜单
 if(item.children !== undefined && item.children.length > 0){
 $.each(item.children,function(j,item2){
  html += '<dd>';
  html += '<a href="javascript:;" data-url="'+item2.url+'" nav-id="'+item2.id+'"><i class="'+item2.icon+'"></i><cite>'+item2.title+'</cite></a>';

 });
 //渲染html
 $('#admin-navbar-side').html(html);

//触发事件
var active = {

  element.tabAdd('admin-tab', {
