Implement multiple routing implementations in Vue-Router2.X
Below I will share with you a summary of various routing implementation methods of Vue-Router2.X. It has a good reference value and I hope it will be helpful to everyone.
Note: vue-router 2 is only applicable to Vue2.x version. Below we will talk about how to use vue-router 2 to implement the routing function based on vue2.0.
It is recommended to use npm to install.
npm install vue-router
1. Using routing
In main.js, you need to explicitly install the routing function:
import Vue from 'vue' import VueRouter from 'vue-router' import App from './App.vue' Vue.use(VueRouter)
1. Define the component, here we use import from other files
import index from './components/index.vue' import hello from './components/hello.vue'
2. Define the route
const routes = [
{ path: '/index', component: index },
{ path: '/hello', component: hello },
]3. Create a router instance, and then Pass routes configuration
const router = new VueRouter({
routes
})4. Create and mount the root instance. Inject routes through router configuration parameters, so that the entire application has routing functions
const app = new Vue({
router,
render: h => h(App)
}).$mount('#app')After the above configuration, the components matched by the routes will be rendered to the
Then the App.vue should write like this:
<template> <p id="app"> <router-view></router-view> </p> </template> index.html里呢要这样写： <body> <p id="app"></p> </body>
This will render it The page is mounted to the p with the id of app.
2. Redirect redirect
const routes = [
{ path: '/', redirect: '/index'}, // 这样进/ 就会跳转到/index
{ path: '/index', component: index }
]3. Nested routing
const routes = [
{ path: '/index', component: index,
children: [
{ path: 'info', component: info}
]
}
]You can access the info component through /index/info
4. Lazy loading
const routes = [
{ path: '/index', component: resolve => require(['./index.vue'], resolve) },
{ path: '/hello', component: resolve => require(['./hello.vue'], resolve) },
]No need to use lazy loading All components will be loaded at once, and only that component will be loaded when you access that component. For applications with many components, the first loading speed will be improved.
5.
In vue-router 2,
<!-- 字符串 -->
<router-link to="home">Home</router-link>
<!-- 渲染结果 -->
<a href="home" rel="external nofollow" >Home</a>
<!-- 使用 v-bind 的 JS 表达式 -->
<router-link v-bind:to="'home'">Home</router-link>
<!-- 不写 v-bind 也可以，就像绑定别的属性一样 -->
<router-link :to="'home'">Home</router-link>
<!-- 同上 -->
<router-link :to="{ path: 'home' }">Home</router-link>
<!-- 命名的路由 -->
<router-link :to="{ name: 'user', params: { userId: 123 }}">User</router-link>
<!-- 带查询参数，下面的结果为 /register?plan=private -->
<router-link :to="{ path: 'register', query: { plan: 'private' }}">Register</router-link>6. Routing information object
1.$route.path
String, corresponding to the path of the current route, is always resolved to an absolute path, such as "/foo/bar".
2.$route.params
A key/value object, including dynamic fragments and full matching fragments. If there are no routing parameters, it is an empty object.
3.$route.query
A key/value object representing URL query parameters. For example, for the path /foo?user=1, $route.query.user == 1, or an empty object if there are no query parameters.
4.$route.hash
The hash value of the current route (without #), if there is no hash value, it is an empty string.
5.$route.fullPath
The URL after completion of parsing, including the full path of query parameters and hash.
6.$route.matched
An array containing the routing records of all nested path fragments of the current route. Route records are copies of objects in the routes configuration array (and in the children array).
Based on the above, a main.js including redirection, nested routing, and lazy loading is as follows:
import Vue from 'vue'
import VueRouter from 'vue-router'
import App from './App'
Vue.use(VueRouter)
const router = new VueRouter({
routes:[
{ path: '/', redirect: '/index' },
{ path: '/index', component: resolve => require(['./components/index.vue'], resolve),
children:[
{ path: 'info', component: resolve => require(['./components/info.vue'], resolve) }
]
},
{ path: '/hello', component: resolve => require(['./components/hello.vue'], resolve) },
]
})
const app = new Vue({
router,
render: h => h(App)
}).$mount('#app')The above is what I compiled Everyone, I hope it will be helpful to everyone in the future.
