vue.js 二级路由/三级路由

为什么要用二级和三级路由？

当项目中有多个时，就必须使用分级路由；

如果路由不分级，又有多个 ,全部都是定义为一级路由，那么项目中的的内容显示就会混乱；这是不友好的；

如果对路由进行分级，那么当触发某个二级或三级路由时，此路由就会将对应组件内容传给自己的父级路由组件里面的，这样就不会混乱；

一级路由被触发时，自然会找自己所注册的根组件的

二级路由

为一级路由添加一个 children 属性数组，并将二级路由放入；

path 属性决定跳转后 url 地址栏的的显示

//main.js //一级路由 import About from './components/about/About' //二级路由 import Contact from './components/about/Contact' import Delivery from './components/about/Delivery' import History from './components/about/History' import OrderingGuide from './components/about/OrderingGuide' const router= new VueRouter({ routes:[ {path:'/about',name:'about',component:About,children:[ {path:'/about/contsssssssssssssssact',name:'contactLink',component:Contact}, {path:'/history',name:'historyLink',component:History}, {path:'/',name:'deliveryLink',component:Delivery}, {path:'/orderingGuide',name:'orderingGuideLink',component:OrderingGuide}, ]}, {path:'*',redirect:'/'} ], mode:"history" });

三级路由

和二级路由差不多

const router= new VueRouter({ routes:[ {path:'/',name:'home',component:Home}, {path:'/menu',name:'menu',component:Menu}, {path:'/admin',name:'admin',component:Admin}, {path:'/about',name:'about',component:About,redirect: {name:'contactLink'},children:[ //二级路由 {path:'/about/contact',name:'contactLink',component:Contact}, {path:'/history',name:'historyLink',component:History}, {path:'/delivery',name:'deliveryLink',component:Delivery}, {path:'/orderingGuide',name:'orderingGuideLink',component:OrderingGuide,redirect:{name:'phonelink'},children: [ //三级路由 {path:'/phone',name:'phonelink',component:Phone}, {path:'/name',name:'namelink',component:Name} ]}, ]}, {path:'/login',name:'login',component:Login}, {path:'/register',name:'register',component:Register}, {path:'*',redirect:'/'} ], mode:"history" });
