vue-router(二)后代路由

关键字:router,children ,router-link,router-view,router-link-active
先理解什么是children?
后代路由为某路由中用到router-view时,会默认加载的路由中的后代路由。
eg:
这里通过点击切换tab实现动态切换路由
先看目录结构:

aslide组件:
<div> <ul class="tabBar"> <li v-for="(item,index) in tabList" :key="index"> <router-link :to="{path:item.url}">{{item.tit}}</router-link> </li> </ul> <router-view class="cont"></router-view> </div>
样式:
.tabBar { width: 100%; height: 90px; display: flex; border-bottom: 1px solid #ccc; } .tabBar li { display: flex; flex: 1; height: 90px; } .tabBar li a { width: 100%; line-height: 90px; display: block; text-align: center; } .router-link-active { color: red; /*background-color: #003399;*/ border-bottom: 1px solid red; } .cont { display: flex; justify-content: center; align-items: center; }
js:
export default { data() { return { isShow: true, tabList: [ { url: '/a', tit: "One" }, { url: '/b', tit: "Two" }, { url: '/c', tit: "Three" } ] } } }
下来我们还需要对router.js路由模块进行 配置
import Vue from 'vue' import Router from 'vue-router' Vue.use(Router); Router.prototype.animate = 0; const _import = file => () => import('@/views/' + file + '.vue'); const _import_ = file => () => import('@/components/' + file + '.vue'); /* * slide:页面切换动画 * login:是否需要登陆 * */ Vue.use(Router); export default new Router({ linkActiveClass: "router-link-active",//后代路由被激活时,给路由标签添加指定样式 routes: [ { path: '/', name: '首页', component: _import('home/index'), children: [ { path: '', redirect: '/a' },//访问首页的时候默认访问后代路由中的a { path: '/a', component: _import_('common/a') }, { path: '/b', component: _import_('common/b') }, { path: '/c', component: _import_('common/c') }] }, { path: "/list", name: "list", component: _import("home/list"), meta: { slide: 1, login: true } }, { path: "/search", name: "search", component: _import("search/index"), meta: { slide: 1 } }, { path: "/center", name: "center", component: _import("center/index"), meta: { slide: 1 } },] })
主要核心部分如上,我们需要注意的这个属性linkActiveClass这个属性指定了后代路由被激活时所添加的样式。
实现的思路为:当点击上述router-link中的路由时,实现动态改变router-view中的后代路由以此实现tab的切换。而后代路由中的第一项:redirect:/a意思是默认访问首页的时候,后代路由默认显示哪个
