vue 路由使用

1.安装

2.使用

3.router几个用法

一 安装

npm安装

npm install vue-router

二 使用

1.绑定vue对象

2.异步加载组件 component: () => import('../views/mysetting/person')

<script>
  import Vue from 'vue'
  import Router from 'vue-router'
  import login from '../views/login'

  Vue.use(Router)

  export default new Router({
    routes: [
      {
        path: '/login',
        name: 'login',
        component: login
      }
    ]
  })
</script>

// The Vue build version to load with the `import` command
// (runtime-only or standalone) has been set in webpack.base.conf with an alias.
import Vue from 'vue'
import App from './App'
import router from './router'
import ElementUI from 'element-ui';
import 'element-ui/lib/theme-chalk/index.css';

Vue.config.productionTip = false
Vue.use(ElementUI);

/* eslint-disable no-new */
new Vue({
  el: '#app',
  router,
  components: { App },
  template: '<App/>'
})

import Vue from 'vue'
import Router from 'vue-router'
import HelloWorld from '@/components/HelloWorld'
import login from '../views/login'
import index from '../views/index'

Vue.use(Router)

export default new Router({
  routes: [
    {
      path: '/login',
      name: 'login',
      component: login
    },
    {
      path: '/',
      redirect: '/index',
      name: 'index',
      component: index
    },
    {
      path: '/index',
      name: 'index',
      component: index,
      children: [
        {
          path: '/person/:id',
          name: 'person',
          component: () => import('../views/mysetting/person'),
        },
        {
          path: '/department',
          name: 'department',
          component: () => import('../views/mysetting/department'),
        }
      ]
    }
  ]
})

二 router几个用法

   1.跳转页面：router-view   router-link

<router-view></router-view>

<router-link to="/login">登录页面</router-link>
2.重定向：redirect

 {
        path: '/',
        redirect: '/login',
        component: login
      }

  3.嵌套路由：children

import Vue from 'vue'
import Router from 'vue-router'
import HelloWorld from '@/components/HelloWorld'
import login from '../views/login'
import index from '../views/index'
import person from '../views/mysetting/person'
import department from '../views/mysetting/department'

Vue.use(Router)

export default new Router({
  routes: [
    {
      path: '/login',
      name: 'login',
      component: login
    },
    {
      path: '/',
      redirect:'/index',
      name: 'index',
      component: index
    },
    {
      path: '/index',
      name: 'index',
      component: index,
      children:[
        {
          path: '/person/:id',
          name: 'person',
          component: person,
        },
        {
          path: '/department',
          name: 'department',
          component: department,
        }
      ]
    }
  ]
})

4.命令路由：name 

export default new Router({
    routes: [
       
      {
        path: '/login',
        name: 'login',
        component: login
      }
    ]
  })

  <!--<router-link to="/person/123">个人信息</router-link>-->
                   <router-link :to="{name:'person', params: { id: 123 }}">个人信息</router-link>

 5.js导航

<el-button @click="gotoRouter('/person/123')">跳转</el-button>
<el-button @click="gotoRouter2('/person/123')">跳转</el-button>
<el-button @click="gotoRouter3('person',123)">跳转</el-button>
<el-button @click="gotoRouter4('person',123)">跳转</el-button>

 gotoRouter(path){
        this.$router.push(path)   //字符串  http://localhost:8080/#/person/123
      },
      gotoRouter2(path){
        this.$router.push({path:path})  //对象  http://localhost:8080/#/person/123
      },
      gotoRouter3(name,id){
        this.$router.push({name:'person',params:{id:123}})   //命令路由 http://localhost:8080/#/person/123
      },
      gotoRouter4(name,id){
        this.$router.push({path:'person',query:{id:123}})   //带参数查询 对应：http://localhost:8080/#/person?id=123
      }
