詳解VUE Element-UI多級(jí)菜單動(dòng)態(tài)渲染的組件
以下是組件代碼:
<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>
外部調(diào)用也比較簡(jiǎn)單
<!--左側(cè)菜單組件--> <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,完成此菜單需要后端的配合,筆者這里后端給出的數(shù)據(jù)為:
{ "entity": null, "childs": [ { "entity": { "id": 1, "parentMenuId": 0, "name": "systemManage", "icon": "el-icon-message\r\n", "alias": "系統(tǒng)管理", "state": "ENABLE", "sort": 0, "value": null, "type": "NONE", "discription": "用于系統(tǒng)管理的菜單", "createUserId": 1 }, "childs": [ { "entity": { "id": 3, "parentMenuId": 1, "name": "authManage", "icon": "el-icon-loading", "alias": "權(quán)限管理", "state": "ENABLE", "sort": 0, "value": "/system/auth", "type": "LINK", "discription": "用于權(quán)限管理的菜單", "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": "用于角色管理的菜單", "createUserId": 1 }, "childs": null }, { "entity": { "id": 2, "parentMenuId": 1, "name": "menuManage", "icon": "el-icon-edit", "alias": "菜單管理", "state": "ENABLE", "sort": 2, "value": "/system/menu", "type": "LINK", "discription": "用于菜單管理的菜單", "createUserId": 1 }, "childs": null }, { "entity": { "id": 5, "parentMenuId": 1, "name": "groupManage", "icon": "el-icon-mobile-phone\r\n", "alias": "分組管理", "state": "ENABLE", "sort": 3, "value": "/system/group", "type": "LINK", "discription": "用于分組管理的菜單", "createUserId": 1 }, "childs": null } ] }, { "entity": { "id": 6, "parentMenuId": 0, "name": "userManage", "icon": "el-icon-news", "alias": "用戶管理", "state": "ENABLE", "sort": 1, "value": null, "type": "NONE", "discription": "用于用戶管理的菜單", "createUserId": 1 }, "childs": [ { "entity": { "id": 7, "parentMenuId": 6, "name": "accountManage", "icon": "el-icon-phone-outline\r\n", "alias": "帳號(hào)管理", "state": "ENABLE", "sort": 0, "value": "", "type": "NONE", "discription": "用于帳號(hào)管理的菜單", "createUserId": 1 }, "childs": [ { "entity": { "id": 14, "parentMenuId": 7, "name": "emailManage", "icon": "el-icon-sold-out\r\n", "alias": "郵箱管理", "state": "ENABLE", "sort": 0, "value": "/content/email", "type": "LINK", "discription": "用于郵箱管理的菜單", "createUserId": 1 }, "childs": null }, { "entity": { "id": 13, "parentMenuId": 7, "name": "passManage", "icon": "el-icon-service\r\n", "alias": "密碼管理", "state": "ENABLE", "sort": 1, "value": "/content/pass", "type": "LINK", "discription": "用于密碼管理的菜單", "createUserId": 1 }, "childs": null } ] }, { "entity": { "id": 8, "parentMenuId": 6, "name": "integralManage", "icon": "el-icon-picture", "alias": "積分管理", "state": "ENABLE", "sort": 1, "value": "/user/integral", "type": "LINK", "discription": "用于積分管理的菜單", "createUserId": 1 }, "childs": null } ] }, { "entity": { "id": 9, "parentMenuId": 0, "name": "contentManage", "icon": "el-icon-rank", "alias": "內(nèi)容管理", "state": "ENABLE", "sort": 2, "value": null, "type": "NONE", "discription": "用于內(nèi)容管理的菜單", "createUserId": 1 }, "childs": [ { "entity": { "id": 10, "parentMenuId": 9, "name": "classifyManage", "icon": "el-icon-printer", "alias": "分類管理", "state": "ENABLE", "sort": 0, "value": "/content/classify", "type": "LINK", "discription": "用于分類管理的菜單", "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": "用于文章管理的菜單", "createUserId": 1 }, "childs": null }, { "entity": { "id": 12, "parentMenuId": 9, "name": "commentManage", "icon": "el-icon-share", "alias": "評(píng)論管理", "state": "ENABLE", "sort": 2, "value": "/content/comment", "type": "LINK", "discription": "用于評(píng)論管理的菜單", "createUserId": 1 }, "childs": null } ] } ] }
總結(jié):當(dāng)遇到多叉樹或無限層級(jí)問題時(shí),vue的遞歸組件是個(gè)比較好的解決方案,可以較大的節(jié)約開發(fā)時(shí)間降低開發(fā)成本。
