Summary of various routing implementation methods in Vue-Router2.X, vue-router2.x Routing
Note: vue-router 2 is only applicable to Vue2.x. The following describes how to use vue-router 2 to implement Routing Based on vue2.0.
We recommend that you use npm for installation.
npm install vue-router
1. Use 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, which is imported from other files.
import index from './components/index.vue'import hello from './components/hello.vue'
2. Define a route
const routes = [ { path: '/index', component: index }, { path: '/hello', component: hello },]
3. Create a router instance and pass the routes Configuration
const router = new VueRouter({ routes})
4. Create and mount the root instance. Configure parameters to inject routes through the router, so that the entire application has the routing function.
const app = new Vue({ router, render: h => h(App)}).$mount('#app')
After the above configuration, the components matching the route will be rendered to <router-view> </router-view> in App. vue.
The App. vue should be written as follows:
<Template> <div id = "app"> <router-view> </div> </template> index.html: <body> <div id = "app"> </div> </body>
In this way, the rendered page will be mounted to the div with the id of app.
2. redirect
Const routes = [{path: '/', redirect: '/Index'}, // in this way,/will jump to/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) },]
If you load the component Through laziness, it will not load all the components at one time, but it will be loaded only when you access the component. Applications with many components increase the loading speed for the first time.
V. <router-link>
In vue-router 2, Use <router-link> </router-link> to replace the tag in version 1.
<! -- String --> <router-link to = "home"> Home </router-link> <! -- Rendering result --> <a href = "home" rel = "external nofollow"> Home </a> <! -- Use the JS expression of v-bind --> <router-link v-bind: to = "'home'"> home </router-link> <! -- Do not write v-bind, just like binding other attributes --> <router-link: to = "'home'"> home </router-link> <! -- Same as above --> <router-link: to = "{path: 'home'}"> home </router-link> <! -- Named route --> <router-link: to = "{name: 'user', params: {userId: 123 }}"> user </router-link> <! -- With query parameters, the following result is/register? Plan = private --> <router-link: to = "{path: 'register ', query: {plan: 'private'}"> register </router-link>
Vi. Routing Information Objects
1. $ route. path
String, which corresponds to the current route path. It is always resolved to an absolute path, for example, "/foo/bar ".
2. $ route. params
A key/value object contains dynamic segments and fully-matched segments. If there is no route parameter, it is an empty object.
3. $ route. query
A key/value object, indicating URL query parameters. For example, for path/foo? User = 1, $ route. query. user = 1. If no query parameter exists, it is an empty object.
4. $ route. hash
The hash value of the current route (without #). If there is no hash value, it is a null string.
5. $ route. fullPath
The URL after resolution, including the query parameters and the complete hash path.
6. $ route. matched
An array that contains route records of all nested path segments of the current route. A route record is a copy of the objects in the routes configuration array (also in the children array ).
Based on the above, a main. js that includes 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')
