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: 'https://www.jb51.net/', // 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="https://www.jb51.net/">/</router-link></li> <li><router-link to="https://www.jb51.net/" 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?foo=bar </router-link> </li> <li><!-- #635 --> <router-link :to="{ name: 'user', params: { username: 'evan' }, query: { foo: 'bar' }}" exact> /users/evan?foo=bar (named view + exact match) </router-link> </li> <li> <router-link :to="{ path: '/users/evan', query: { foo: 'bar', baz: 'qux' }}"> /users/evan?foo=bar&baz=qux </router-link> </li> <li><router-link to="/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: 'https://www.jb51.net/', 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>' }

<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <title>Title</title> </head> <body> <script src="https://unpkg.com/vue/dist/vue.js"></script> <script src="https://unpkg.com/vue-router/dist/vue-router.js"></script> <div> <h1>Hello App!</h1> <p> <!-- 使用 router-link 组件来导航. --> <!-- 通过传入 `to` 属性指定链接. --> <!-- <router-link> 默认会被渲染成一个 `<a>` 标签 --> <router-link to="/foo">Go to Foo</router-link> <router-link to="/bar">Go to Bar</router-link> </p> <!-- 路由出口 --> <!-- 路由匹配到的组件将渲染在这里 --> <router-view></router-view> </div> <script> var Foo = { template: '<div>foo</div>' } var Home= { template:'<div>Home</div>' } var Bar = { template: '<div>bar</div>' } // 2. 定义路由 // 每个路由应该映射一个组件。 其中"component" 可以是 // 通过 Vue.extend() 创建的组件构造器, // 或者,只是一个组件配置对象。 // 我们晚点再讨论嵌套路由。 var routes = [ { path: 'https://www.jb51.net/', component: Home}, { path: '/foo', component: Foo }, { path: '/bar', component: Bar } ] // 3. 创建 router 实例,然后传 `routes` 配置 // 你还可以传别的配置参数, 不过先这么简单着吧。 var router = new VueRouter({ routes // (缩写)相当于 routes: routes }) // 4. 创建和挂载根实例。 // 记得要通过 router 配置参数注入路由, // 从而让整个应用都有路由功能 var app = new Vue({ router, el:'#app' }) </script> </body> </html>
