html

router-link：跳转链接

参数to：就是跳转到的链接位置

二层链接 eg：

<router-link to="/users/evan">/users/evan</router-link>

需要配置所对应的对应的children

children所对应的参数

path：可分我固定的参数url 和带参数的区别于：（冒号）

name：对应的参数的模块名称（动态传参数）

component:可以传多个组件

eg：
{ path: '/',
 // a single route can define multiple named components
 // which will be rendered into <router-view>s with corresponding names.
 components: {
  default: Foo,
  a: Bar,
  b: Baz
 }
},

:to="{ name: 'user', params: { username: 'evan' }, query: { foo: 'bar' }}"

参数说明params 对应的是children的path的值，to中的name为vueRouter中的name

当要传多个参数时

{ path: ':username/:aaa', name: 'user', component: User }

也可以利用query传值

query: { foo: 'bar' }
eg: path: ':username'

redirect：链接直接指向指定的方向（重定向）

beforeEnter：
·
{ path: '/dashboard', component: Dashboard, beforeEnter: requireAuth },
function requireAuth (route, redirect, next) {
 if (!auth.loggedIn()) {
 redirect({
  path: '/login',
  query: { redirect: route.fullPath }
 })
 } else {
 next()
 }
}

使用props将组件和路由解耦：

在组件中使用$route会使之与其对应路由形成高度耦合，从而使组件只能在某些特定的url上使用，限制了其灵活性。

对应的参数的值的获取

{{$route.params.username1 }}
 { path: '/users', component: Users,
  children: [
  { path: ':username', name: 'user', component: User }
  ]
 }

eg:

 <ul>
  <li><router-link to="/">/</router-link></li>
  <li><router-link to="/" exact>/ (exact match)</router-link></li>

  <li><router-link to="/users">/users</router-link></li>
  <li><router-link to="/users" exact>/users (exact match)</router-link></li>

  <li><router-link to="/users/evan">/users/evan</router-link></li>
  <li><router-link to="/users/evan#foo">/users/evan#foo</router-link></li>
  <li>
   <router-link :to="{ path: '/users/evan', query: { foo: 'bar' }}">
   /users/evan"{ name: 'user', params: { username: 'evan' }, query: { foo: 'bar' }}" exact>
   /users/evan"{ path: '/users/evan', query: { foo: 'bar', baz: 'qux' }}">
   /users/evan"/about">/about</router-link></li>

  <router-link tag="li" to="/about">
   <a>/about (active class on outer element)</a>
  </router-link>
  </ul>

const router = new VueRouter({
 mode: 'history',
 base: __dirname,
 routes: [
 { path: '/', component: Home },
 { path: '/about', component: About },
 { path: '/users', component: Users,
  children: [
  { path: ':username', name: 'user', component: User }
  ]
 }
 ]
})

js:vue-router配置

router-view：组件的放置位置

对应的链接所对应的组件的配置

路由底下的子组件

{ path: '/users', component: Users,
  children: [
  { path: ':username', name: 'user', component: User }
  ]
 }

//组件

Vue.use(VueRouter)

const Home = { template: '<div><h2>Home</h2></div>' }
const About = { template: '<div><h2>About</h2></div>' }

const Users = {
 template: `
 <div>
  <h2>Users</h2>
  <router-view></router-view>
 </div>
 `
}

const User = { template: '<div>{{ $route.params.username }}</div>' }

==================分界线====================

案例：1

<!DOCTYPE html>
<html lang="en">
<head>
 <meta charset="UTF-8">
 <title>Title</title>
</head>
<body>
<script src="/UploadFiles/2021-04-02/vue.js">

实现效果

=====================================
案例：2
path的二级链接固定参数


<div id="app">
 <h1>Data Fetching</h1>
 <ul>
 <li><router-link to="/">/</router-link></li>
 <li><router-link to="/user/even" exact>/users (exact match)</router-link></li>
</ul>
 <router-view class="view"></router-view>
</div>
<script>
 var Users = {
  template: '<div><h2>Users</h2><router-view></router-view> </div>'
 }
 var User = {
  template: '<div>{{$route.params.username1 }}</div>'
 }
 var Home = {
  template: '<div>Home</div>'
 }
 var router = new VueRouter({
  routes: [
   { path: '/', component: Home,},
   // 动态路径参数 以冒号开头
   { path: '/user', component: Users,
    children: [
     { path: ':username1', name: 'bbb', component: User }
    ]}
  ]
 })
 new Vue({
  el:"#app",
  router,
  data:{
   name:111
  }
 })



二级链接动态参数


<div id="app">
 <h1>Data Fetching</h1>
 <ul>
 <li><router-link to="/">/</router-link></li>
 <li><router-link :to="{ name: 'bbb', params: { username: name}}" exact>/users/evan"view"></router-view>
</div>
<script>
 var Users = {
  template: '<div><h2>Users</h2><router-view></router-view> </div>'
 }
 var User = {
  template: '<div>{{$route.params.username }}</div>'
 }
 var Home = {
  template: '<div>Home</div>'
 }
 var router = new VueRouter({
  routes: [
   { path: '/', component: Home,},
   // 动态路径参数 以冒号开头
   { path: '/user', component: Users,
    children: [
     { path: ':username', name: 'bbb', component: User }
    ]}
  ]
 })
 new Vue({
  el:"#app",
  router,
  data:{
   name:111
  }
 })
</script>


实现效果
 
注意与上一个实例进行对比发现链接的地址并没有发生改变，刷新后会返回首页
如何解决这个问题呢
==============案例=======================


<div id="app">
 <h1>Data Fetching</h1>
 <ul>
 <li><router-link to="/">/</router-link></li>
 <li><router-link :to='{name:"user", params:{ id:111 }}'>111</router-link>
 </li>
</ul>
 <router-view class="view"></router-view>
</div>
<script>
 var Users = {
  template: '<div><h2>Users</h2><div>{{$route.params.id}}</div></div>'
 }
 var Home = {
  template: '<div>Home</div>'
 }
 var router = new VueRouter({
  routes: [
   { path: '/', component: Home,},
   // 动态路径参数 以冒号开头
   { path: '/user/:id', name:'user', component: Users}
  ]
 })
 new Vue({
  el:"#app",
  router,
  data:{
   name:111
  }
 })
</script>
