js实现左侧菜单栏递归循环遍历

首先html布局

{
title: '首页',
key: '/home'
},
{
title: 'UI',
key: '/ui',
children: [
{
title: '按钮',
key: '/ui/buttons',
},
{
title: '弹框',
key: '/ui/modals',
},
{
title: 'Loading',
key: '/ui/loadings',
},
{
title: '通知提醒',
key: '/ui/notification',
},
{
title: '全局Message',
key: '/ui/messages',
},
{
title: 'Tab页签',
key: '/ui/tabs',
},
{
title: '图片画廊',
key: '/ui/gallery',
},
{
title: '轮播图',
key: '/ui/carousel',
}
]
},
{
title: '表单',
key: '/form',
children: [
{
title: '登录',
key: '/form/login',
},
{
title: '注册',
key: '/form/reg',
}
]
},
{
title: '表格',
key: '/table',
children: [
{
title: '基础表格',
key: '/table/basic',
},
{
title: '高级表格',
key: '/table/high',
}
]
},
{
title: '富文本',
key: '/rich'
},
{
title: '城市管理',
key: '/city'
},
{
title: '订单管理',
key: '/order',
btnList: [
{
title: '订单详情',
key: 'detail'
},
{
title: '结束订单',
key: 'finish'
}
]
},
{
title: '员工管理',
key: '/user'
},
{
title: '车辆地图',
key: '/bikeMap'
},
{
title: '图标',
key: '/charts',
children: [
{
title: '柱形图',
key: '/charts/bar'
},
{
title: '饼图',
key: '/charts/pie'
},
{
title: '折线图',
key: '/charts/line'
},
]
},
{
title: '权限设置',
key: '/permission'
},
];

js逻辑
var ul=&＃8221;;

function appednMenu(data) {
data.forEach(function (item,index) {
if(item.children){
ul+='

没有写样式 简易版本的菜单栏
