router/index.js里面配置路由

import Vue from 'vue'
import Router from 'vue-router'
import Home from '@/components/home'
import About from '@/components/about'

Vue.use(Router)

export default new Router({
  mode:'history',
  routes: [
    {
      path: '/home',
      name: 'Home',
      component: Home
    },
    {
      path: '/about',
      name: 'About',
      component: About
    },
    { path: '/', redirect:'/home' }
    
  ]
})

app.vue 

<template>
  <div id="app">
   <router-link :to="{path:'/home'}">home</router-link>
   <router-link :to="{path:'/about'}">about</router-link>
    <router-view/>
  </div>
</template>

<script>
export default {
  name: 'App'
}
</script>

<style>
#app {
  font-family: 'Avenir', Helvetica, Arial, sans-serif;
  -webkit-font-smoothing: antialiased;
  -moz-osx-font-smoothing: grayscale;
  text-align: center;
  color: #2c3e50;
  margin-top: 60px;
}
</style>

home.vue

<template>
  <div class="home">
   <p>{{msg}}</p>
  <transition name="slide-fade">
   <v-modal v-show="modalStatus" :title="title" :content="content" :btnType="btnType">
    <slot>
      <button class="danger" name="danger"  @click="modalStatus=false">确定</button>
       <button class="default" name="default" @click="modalStatus=false">取消</button>
    </slot>
   </v-modal>
  </transition>
   <button @click="openHomeModal()">打开modal</button>


  
  </div>
</template>

<script>
import Modal from "@/components/modal.vue";
export default {
  name: "HelloWorld",
  data() {
    return {
      msg: "我是首页信息",
      modalStatus: false,
      title: "我是首页，我骄傲",
      content: "我是首页的内容",
    };

    "v-modal": Modal
  },
  methods: {
    openHomeModal() {
      this.modalStatus = true;
    }
  }

<!-- Add "scoped" attribute to limit CSS to this component only -->
<style scoped lang="scss">
