Vue-router路由使用

1、创建路由

import Vue from 'vue'
import VueRouter from 'vue-router'
//1 注册插件
Vue.use(VueRouter)



const routes = [
  {
    path: '',
    redirect: '/home'
  },
  {
    path: '/home',
    component: Home,
    meta: {
      title: '首页'
    },
    children: [
      {
        path: '',
        redirect: 'news'
      },
      {
        path: 'news',
        component: HomeNews
      },
      {
        path: 'message',
        component: HomeMessage
      }
    ]
  },
  {
    path: '/about/:id',
    component: About,
    meta: {
      title: '关于'
    }
  },
  {
    path: '/profile',
    component: Profile,
    meta: {
      title: '档案'
    }
  }
]
//2 创建路由
const router = new VueRouter({
  routes,
  mode: 'history'
})

//3 导出路由 然后再入口文件 进行注册
export default router

2、配置路由

import Vue from 'vue'
import VueRouter from 'vue-router'

const Home = () => import('../components/Home')
const About = () => import('../components/About')
const Profile = () => import('../components/Profile')
const HomeNews = () => import('../components/HomeNews')
const HomeMessage = () => import('../components/HomeMessage')

Vue.use(VueRouter)

const routes = [
  {
    path: '',
    redirect: '/home'
  },
  {
    path: '/home',
    component: Home,
    meta: {
      title: '首页'
    },
    children: [
      {
        path: '',
        redirect: 'news'
      },
      {
        path: 'news',
        component: HomeNews
      },
      {
        path: 'message',
        component: HomeMessage
      }
    ]
  },
  {
    path: '/about/',
    component: About,
    meta: {
      title: '关于'
    }
  },
  {
    path: '/profile',
    component: Profile,
    meta: {
      title: '档案'
    }
  }
]

const router = new VueRouter({
  routes,
  mode: 'history'
})


export default router

3、在App.vue进行设置

<router-link to="/home">首页</router-link>
   <router-link to="/about">关于</router-link>
   <router-view></router-view>

4、路由跳转

<template>
  <div id="app">
   <button @click="homeClick">首页</button>
   <button @click="aboutClick">关于</button>
   <router-view></router-view>
  </div>
</template>

<script>


export default {
  name: 'App',
  methods: {
    homeClick() {
      this.$router.push('/home')
    },
    aboutClick() {
      this.$router.push('/about')
    }
  }
  
}
</script>

<style>

</style>

5、路由传参有2中方式   params和query

5.1 params传递  分为几步     

第一步： 配置路由格式   （这里的id并不是唯一，你也可以为其定义aaa，bbbb等等 都可以）

 path: '/about/:id',
 component: About,

第二步

<template>
  <div id="app">
   <button @click="homeClick">首页</button>
   <button @click="aboutClick">关于</button>
   <router-view></router-view>
  </div>
</template>
<script>

export default {
  name: 'App',
  data() {
    return {
      userId: 'zhangsan'
    }
  },
  methods: {
    homeClick() {
      this.$router.push('/home')
    },
    aboutClick() {
      this.$router.push('/about/'+this.userId)
    }
  }
  
}
</script>

<style>

</style>

效果如下：

而且我们也可以在关于当前页面拿到这个id  格式如下：

<template>
  <div>
    <h2>我是关于的内容</h2>
    <ul>
      <li>关于内容</li>
      <li>关于内容</li>
      <li>关于内容</li>
      <li>关于内容</li>
    </ul>
   {{$route.params.id}}
  </div>
</template>

<script>
export default {
  name: 'About',
}

5.2 query方式进行传参

this.$router.push({
        path: '/profile',
        query: {name: 'james', age: 18, height: 199}
      })
