layuiAdmin利用json數據動態生成左側菜單欄的方法

layuiAdmin單頁版根據后臺json數據動態生成左側菜單欄

使用模板方式加載菜單

lay-url=“菜單接口”

lay-headers=“將token帶入請求頭”，如果沒有，去掉就行

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

layui.data(‘layuiAdmin’).token 調用本地存儲的token,token名需要和本地存儲對應

json字段名不需要和這里的一樣，json字段名改變，模板里面也要相應的修改

<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">
