这篇文章主要讲解了“vue-router中children怎么使用”,文中的讲解内容简单清晰,易于学习与理解,下面请大家跟着小编的思路慢慢深入,一起来研究和学习“vue-router中children怎么使用”吧!
比如页面左侧显示菜单,右侧显示不同菜单下的内容,类似如下element网站,那么右侧部分的内容就是当前页面的children
存在如下场景,点击导航一跳转至页面1,导航二跳转页面2,且页面1中存在子页面
路由js如下:
const routes = [{ path: '/', name: 'Home', component: Home, children: [{ path: '/page1', name: 'page1', component: function () { return import( /* webpackChunkName: "about" */ '../views/Page1.vue') }, children: [{ path: '/page1Son', name: 'page1Son', component: function () { return import( /* webpackChunkName: "about" */ '../views/Page1Son.vue') } }], }, { path: '/page2', name: 'page2', component: function () { return import( /* webpackChunkName: "about" */ '../views/Page2.vue') } }] } ]
首页代码如下:
<template> <div class="home"> <el-menu default-active="2" class="el-menu-vertical-demo"> <el-submenu index="1"> <template slot="title"> <i class="el-icon-location"></i> <span slot="title"><router-link to="/page1">导航一</router-link></span> </template> </el-submenu> <el-menu-item index="4"> <i class="el-icon-setting"></i> <span slot="title"><router-link to="/page2">导航二</router-link></span> </el-menu-item> </el-menu> <router-view></router-view> </div> </template>
点击导航栏一显示页面1下的内容
点击页面1中的显示按钮,显示页面1的子页面page1Son
点击导航栏二显示页面2
刚开始学习前端技术,再配置路由的时候,发现路由配置中children。
import Vue from 'vue' import Router from 'vue-router' import menus from '@/config/menu-config' Vue.use(Router) export default new Router({ mode: 'history', routes: [ { path: '/table', //name: 'table' 父组件没有页面,不选哟name component: {render: (e) => e("router-view")}, children: [ { path: 'table_show_view', //不需要在前面加 ‘/', 在导航中的index 使用 /table/table_show_view name: 'tableShow', component: () => import('@/components/table/TableView.vue'), }, { path: 'queryTableView', //不需要在前面加 ‘/', 在导航中的index 使用 /table/queryTableView name: 'query_table_view', component: () => import('@/components/table/TableQueryShow.vue'), }, { path: 'selectTableView', //不需要在前面加 ‘/', 在导航中的index 使用 /table/selectTableView name: 'selectTableView', component: () => import('@/components/table/SelectTableView.vue'), }, { //默认跳转页面,当访问 /table时 跳转到 /table_show_view path: '/', name: 'fable_redirect', redirect: '/table/table_show_view', } ] }, { path: '/form', component: {render: (e) => e("router-view")}, children: [ { path: 'form_insert_submit', name: 'formSubmit', component: () => import('@/components/form/FormView.vue'), }, { path: 'query_form_view', name: 'queryFormView', component: () => import('@/components/form/FormView.vue'), }, { //默认跳转页面,当访问 /table时 跳转到 /form/form_insert_submit path: '/', name: 'form_redirect', redirect: '/form/form_insert_submit', } ] }, , { path: '/pagination', component: {render: (e) => e("router-view")}, children: [ { path: 'paginationShow', name: 'paginationShow', component: () => import('@/components/pagination/Pagination.vue'), }, { path: 'paginationTableShow', name: 'paginationTableShow', component: () => import('@/components/pagination/PaginationTableShow.vue'), }, { //默认跳转页面,当访问 /table时 跳转到 /pagination/paginationShow path: '/', name: 'pagination_redirect', redirect: '/pagination/paginationShow', } ] } ] })
导航栏的vue代码如下:NavMenu.vue
<template> <el-row class="tac"> <el-col :span="24"> <el-menu :default-active="this.$route.path" class="el-menu-vertical-demo" router unique-opened @open="handleOpen" @close="handleClose" background-color="#545c64" text-color="#fff" active-text-color="#ffd04b"> <el-submenu index="/table"> <template slot="title"> <i class="el-icon-menu"></i> <span>表格操作学习</span> </template> <el-menu-item-group class="over-hide"> <template slot="title">分组一</template> <el-menu-item class="el-icon-user" index="/table_show_view">表格展示</el-menu-item> <el-menu-item class="el-icon-user" index="/queryTableView">表格查询展示</el-menu-item> <el-menu-item class="el-icon-user" index="/selectTableView">选择框表单</el-menu-item> </el-menu-item-group> </el-submenu> <el-submenu index="/form"> <template slot="title"> <i class="el-icon-menu"></i> <span>表单学习</span> </template> <el-menu-item-group class="over-hide"> <template slot="title">分组一</template> <el-menu-item class="el-icon-user" index="/form_insert_submit">表单输入提交</el-menu-item> <el-menu-item class="el-icon-user" index="/query_form_view">表单查询修改</el-menu-item> </el-menu-item-group> <el-submenu index="2-4"> <template slot="title">选项4</template> <el-menu-item class="el-icon-user" index="/home">选项1</el-menu-item> </el-submenu> </el-submenu> <el-submenu index="/pagination"> <template slot="title"> <i class="el-icon-menu"></i> <span>分页插件</span> </template> <el-menu-item class="el-icon-user" index="/paginationShow">分页查看</el-menu-item> <el-menu-item class="el-icon-user" index="/paginationTableShow">分页获取表数据</el-menu-item> </el-submenu> </el-menu> </el-col> </el-row> </template>
<style scoped> .over-hide { overflow: hidden; } </style>
<script> import menu from '@/config/menu-config' export default { data() { return { menu: menu } }, methods: { handleOpen(key, keyPath) { console.log(key, keyPath) }, handleClose(key, keyPath) { console.log(key, keyPath) } } } </script>
发现点击之后页面没有展现指定页面的功能。
可以看得出,是没有路由展现/table_show_view 路由的信息。
经过排查发现,路由中的children的访问,必须把path路径写全才能访问到。
如上图的配置,如果需要访问/table_show_view,需要完整的访问路径即:/table/table_show_view。
最终我的菜单配置如下:
<template> <el-row class="tac"> <el-col :span="24"> <el-menu :default-active="this.$route.path" class="el-menu-vertical-demo" router unique-opened @open="handleOpen" @close="handleClose" background-color="#545c64" text-color="#fff" active-text-color="#ffd04b"> <el-submenu index="/table"> <template slot="title"> <i class="el-icon-menu"></i> <span>表格操作学习</span> </template> <el-menu-item-group class="over-hide"> <template slot="title">分组一</template> <el-menu-item class="el-icon-user" index="/table_show_view">表格展示</el-menu-item> <el-menu-item class="el-icon-user" index="/table/queryTableView">表格查询展示</el-menu-item> <el-menu-item class="el-icon-user" index="/table/selectTableView">选择框表单</el-menu-item> </el-menu-item-group> <!-- <el-submenu index="1-4"> <template slot="title">选项4</template> <el-menu-item index="/index/home">选项1</el-menu-item> </el-submenu>--> </el-submenu> <el-submenu index="/form"> <template slot="title"> <i class="el-icon-menu"></i> <span>表单学习</span> </template> <el-menu-item-group class="over-hide"> <template slot="title">分组一</template> <el-menu-item class="el-icon-user" index="/form/form_insert_submit">表单输入提交</el-menu-item> <el-menu-item class="el-icon-user" index="/form/query_form_view">表单查询修改</el-menu-item> </el-menu-item-group> <el-submenu index="2-4"> <template slot="title">选项4</template> <el-menu-item class="el-icon-user" index="/index/home">选项1</el-menu-item> </el-submenu> </el-submenu> <el-submenu index="/pagination"> <template slot="title"> <i class="el-icon-menu"></i> <span>分页插件</span> </template> <el-menu-item class="el-icon-user" index="/pagination/paginationShow">分页查看</el-menu-item> <el-menu-item class="el-icon-user" index="/pagination/paginationTableShow">分页获取表数据</el-menu-item> </el-submenu> </el-menu> </el-col> </el-row> </template>
除此之外,再使用路由的地方需要加入: <router-view></router-view> 才能使用路由
<template> <div id="app"> <el-container> <el-header class="header"> <vheader/> </el-header> <el-container> <el-aside class="menus_style"> <navmenu></navmenu> </el-aside> <el-main> <router-view></router-view> </el-main> </el-container> </el-container> </div> </template>
<script> import NavMenu from '@/components/layout/NavMenu' import Header from '@/components/layout/Header' export default { name: 'app', components: { 'navmenu': NavMenu, 'vheader': Header } } </script>
<style> .menus_style{ width: 200px; height: 100%; } .header { background-color: #409EFF; color: #fff; line-height: 60px; } </style>
