詳解layuiAdmin單頁版根據後台json資料動態產生左側選單欄

layuiAdmin單頁版根據後台json資料動態產生左側選單列

使用範本方式載入選單

lay-url=“選單介面”

lay-headers=“將token帶入請求頭”，如果沒有，去掉就行

在範本中使用console.log範例： {{# console.log(1) }}

layui.data('layuiAdmin').token 呼叫本地儲存的token,token名稱需要和本地儲存對應

#json字段名不需要和這裡的一樣，json字段名改變，模板裡面也要相應的修改

<div class="layui-side layui-side-menu">
  <div class="layui-side-scroll">
