笔记

1. 作用：不借助<router-link> 实现路由跳转，让路由跳转更加灵活

2. 具体编码：

   //$router的两个API
   this.$router.push({
   	name:'xiangqing',
   		params:{
   			id:xxx,
   			title:xxx
   		}
   })
   
   this.$router.replace({
   	name:'xiangqing',
   		params:{
   			id:xxx,
   			title:xxx
   		}
   })
   this.$router.forward() //前进
   this.$router.back() //后退
   this.$router.go() //可前进也可后退
   

代码

Message.vue

<template>
	<div>

				<!-- 跳转路由并携带params参数，to的字符串写法 -->
				<!-- <router-link :to="`/home/message/detail/${m.id}/${m.title}`">{{m.title}}</router-link>&nbsp;&nbsp; -->

				<!-- 跳转路由并携带params参数，to的对象写法 -->
				<router-link :to="{
