layuiAdmin單頁(yè)版根據(jù)后臺(tái)json數(shù)據(jù)動(dòng)態(tài)生成左側(cè)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(qǐng)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(diào)用本地存儲(chǔ)的token,token名需要和本地存儲(chǔ)對(duì)應(yīng)

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(yīng)的修改
