<template>
  <div id="app">
    <button @click="toHome">首页</button>
    <button to="/about"  @click="toAbout">关于</button>
    <!-- 相当于占位符 -->
    <router-view></router-view>
  </div>
</template>

<script>
export default {
  name: 'App',
    methods:{
      toHome(){
        this.$router.push('/home')
        //地址不能前进后退
        //this.$router.replace('/home')
      },
      toAbout(){
        this.$router.push('/about')
        //this.$router.replace('/about')
      }
    }
}
</script>

  -webkit-font-smoothing: antialiased;
