Vue programmatic routing navigation

1. Use

Instead of using <router-link>tags, use the api in $router to achieve jumps, which is more flexible

<template>
	<div>
		<ul>
			<li v-for="m in messageList" :key="m.id">
				<!-- 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="{
					name:'xiangqing',
					query:{
						id:m.id,
						title:m.title
					}
				}">
					{
   
   {m.title}}
				</router-link>
				<button @click="pushShow(m)">push查看</button>
				<button @click="replaceShow(m)">replace查看</button>
			</li>
		</ul>
		<hr>
		<router-view></router-view>
	</div>
</template>

<script>
	export default {
      
      
		name:'Message',
		data() {
      
      
			return {
      
      
				messageList:[
					{
      
      id:'001',title:'消息001'},
					{
      
      id:'002',title:'消息002'},
					{
      
      id:'003',title:'消息003'}
				]
			}
		},
		methods: {
      
      
			pushShow(m){
      
      
				this.$router.push({
      
      
					name:'xiangqing',
					query:{
      
      
						id:m.id,
						title:m.title
					}
				})
			},
			replaceShow(m){
      
      
				this.$router.replace({
      
      
					name:'xiangqing',
					query:{
      
      
						id:m.id,
						title:m.title
					}
				})
			}
		},
	}
</script>

this.$router.push()It is a push operation, you can go back to all the previous history records,
this.$router.replace()it is a replacement operation, you can’t go back to the last history record
this.$router.back(), and you can roll back a record, which is consistent with the usage of history.back() and
this.$router.forward()advances a record, and history.forward() ① go(0): Refresh the current page
this.$router.go()② history.go()go (negative integer): go back n records ③ go (positive integer): forward n records
