以下是组件代码:
<template> <div class="navMenu"> <label v-for="navMenu in navMenus"> <el-menu-item v-if="navMenu.childs==null&&navMenu.entity&&navMenu.entity.state==='ENABLE'" :key="navMenu.entity.id" :data="navMenu" :index="navMenu.entity.name" :route="navMenu.entity.value" disabled=""> <i :class="navMenu.entity.icon"></i> <span slot="title">{{navMenu.entity.alias}}</span> </el-menu-item> <el-submenu v-if="navMenu.childs&&navMenu.entity&&navMenu.entity.state==='ENABLE'" :key="navMenu.entity.id" :data="navMenu" :index="navMenu.entity.name"> <template slot="title"> <i :class="navMenu.entity.icon"></i> <span> {{navMenu.entity.alias}}</span> </template> <NavMenu :navMenus="navMenu.childs"></NavMenu> </el-submenu> </label> </div> </template> <script> export default { name: 'NavMenu', props: ['navMenus'], data() { return {} }, methods: {} } </script> <style scoped> </style>
外部调用也比较简单
<!--左侧菜单组件--> <el-menu default-active="0" class="el-menu-vertical-demo" @select="menuSelected" background-color="#F0F6F6" text-color="#3C3F41" active-text-color="black"> <NavMenu :navMenus="leftMenus"></NavMenu> </el-menu>
最后看下效果:
值得一提的是,完成此菜单需要后端的配合,笔者这里后端给出的数据为:
{ "entity": null, "childs": [ { "entity": { "id": 1, "parentMenuId": 0, "name": "systemManage", "icon": "el-icon-message\r\n", "alias": "系统管理", "state": "ENABLE", "sort": 0, "value": null, "type": "NONE", "discription": "用于系统管理的菜单", "createUserId": 1 }, "childs": [ { "entity": { "id": 3, "parentMenuId": 1, "name": "authManage", "icon": "el-icon-loading", "alias": "权限管理", "state": "ENABLE", "sort": 0, "value": "/system/auth", "type": "LINK", "discription": "用于权限管理的菜单", "createUserId": 1 }, "childs": null }, { "entity": { "id": 4, "parentMenuId": 1, "name": "roleManage", "icon": "el-icon-bell", "alias": "角色管理", "state": "ENABLE", "sort": 1, "value": "/system/role", "type": "LINK", "discription": "用于角色管理的菜单", "createUserId": 1 }, "childs": null }, { "entity": { "id": 2, "parentMenuId": 1, "name": "menuManage", "icon": "el-icon-edit", "alias": "菜单管理", "state": "ENABLE", "sort": 2, "value": "/system/menu", "type": "LINK", "discription": "用于菜单管理的菜单", "createUserId": 1 }, "childs": null }, { "entity": { "id": 5, "parentMenuId": 1, "name": "groupManage", "icon": "el-icon-mobile-phone\r\n", "alias": "分组管理", "state": "ENABLE", "sort": 3, "value": "/system/group", "type": "LINK", "discription": "用于分组管理的菜单", "createUserId": 1 }, "childs": null } ] }, { "entity": { "id": 6, "parentMenuId": 0, "name": "userManage", "icon": "el-icon-news", "alias": "用户管理", "state": "ENABLE", "sort": 1, "value": null, "type": "NONE", "discription": "用于用户管理的菜单", "createUserId": 1 }, "childs": [ { "entity": { "id": 7, "parentMenuId": 6, "name": "accountManage", "icon": "el-icon-phone-outline\r\n", "alias": "帐号管理", "state": "ENABLE", "sort": 0, "value": "", "type": "NONE", "discription": "用于帐号管理的菜单", "createUserId": 1 }, "childs": [ { "entity": { "id": 14, "parentMenuId": 7, "name": "emailManage", "icon": "el-icon-sold-out\r\n", "alias": "邮箱管理", "state": "ENABLE", "sort": 0, "value": "/content/email", "type": "LINK", "discription": "用于邮箱管理的菜单", "createUserId": 1 }, "childs": null }, { "entity": { "id": 13, "parentMenuId": 7, "name": "passManage", "icon": "el-icon-service\r\n", "alias": "密码管理", "state": "ENABLE", "sort": 1, "value": "/content/pass", "type": "LINK", "discription": "用于密码管理的菜单", "createUserId": 1 }, "childs": null } ] }, { "entity": { "id": 8, "parentMenuId": 6, "name": "integralManage", "icon": "el-icon-picture", "alias": "积分管理", "state": "ENABLE", "sort": 1, "value": "/user/integral", "type": "LINK", "discription": "用于积分管理的菜单", "createUserId": 1 }, "childs": null } ] }, { "entity": { "id": 9, "parentMenuId": 0, "name": "contentManage", "icon": "el-icon-rank", "alias": "内容管理", "state": "ENABLE", "sort": 2, "value": null, "type": "NONE", "discription": "用于内容管理的菜单", "createUserId": 1 }, "childs": [ { "entity": { "id": 10, "parentMenuId": 9, "name": "classifyManage", "icon": "el-icon-printer", "alias": "分类管理", "state": "ENABLE", "sort": 0, "value": "/content/classify", "type": "LINK", "discription": "用于分类管理的菜单", "createUserId": 1 }, "childs": null }, { "entity": { "id": 11, "parentMenuId": 9, "name": "articleManage", "icon": "el-icon-star-on", "alias": "文章管理", "state": "ENABLE", "sort": 1, "value": "/content/article", "type": "LINK", "discription": "用于文章管理的菜单", "createUserId": 1 }, "childs": null }, { "entity": { "id": 12, "parentMenuId": 9, "name": "commentManage", "icon": "el-icon-share", "alias": "评论管理", "state": "ENABLE", "sort": 2, "value": "/content/comment", "type": "LINK", "discription": "用于评论管理的菜单", "createUserId": 1 }, "childs": null } ] } ] }
总结:当遇到多叉树或无限层级问题时,vue的递归组件是个比较好的解决方案,可以较大的节约开发时间降低开发成本。

稳了!魔兽国服回归的3条重磅消息!官宣时间再确认!
昨天有一位朋友在大神群里分享,自己亚服账号被封号之后居然弹出了国服的封号信息对话框。
这里面让他访问的是一个国服的战网网址,com.cn和后面的zh都非常明白地表明这就是国服战网。
而他在复制这个网址并且进行登录之后,确实是网易的网址,也就是我们熟悉的停服之后国服发布的暴雪游戏产品运营到期开放退款的说明。这是一件比较奇怪的事情,因为以前都没有出现这样的情况,现在突然提示跳转到国服战网的网址,是不是说明了简体中文客户端已经开始进行更新了呢?
