详解layuiAdmin单页版根据后台json数据动态生成左侧菜单栏

layuiAdmin单页版根据后台json数据动态生成左侧菜单栏

使用模板方式加载菜单

lay-url=“菜单接口”

lay-headers=“将token带入请求头”，如果没有，去掉就行

在模板中使用console.log 示例： {{# console.log(1) }}

layui.data(‘layuiAdmin’).token 调用本地存储的token,token名需要和本地存储对应

json字段名不需要和这里的一样，json字段名改变，模板里面也要相应的修改

<div class="layui-side layui-side-menu">   <div class="layui-side-scroll">     <script type="text/html" template lay-url="https://easy-mock.com/mock/5c131015dada7b27ac3a5c36/titi/treemenu"       lay-headers="{'x-auth-token': layui.data('layuiAdmin').token}"       lay-done="layui.element.render('nav', 'layadmin-system-side-menu');" id="TPL_layout">       <ul class="layui-nav layui-nav-tree" lay-shrink="all" id="LAY-system-side-menu"         lay-filter="layadmin-system-side-menu">         {{#            var path =  layui.router().path           ,dataName = layui.setter.response.dataName;                       layui.each(d[dataName], function(index, item){              var hasChildren = typeof item.list === 'object' && item.list.length > 0             ,classSelected = function(){               if(index == 0){                 return hasChildren ?
