How to implement route jump and value passing in vuejs

Vuejs route jump value transfer method: 1. Use the "

The operating environment of this tutorial: windows7 system, vue2.9.6 version, DELL G3 computer.

There are many types of route jump parameters in vue. The ones I commonly use are the following ones

• Jump through router-link

• Route jump through programmatic navigation

1. router-link

<router-link 
 :to="{
  path: &#39;yourPath&#39;, 
  params: { 
   name: &#39;name&#39;, 
   dataObj: data
  },
  query: {
   name: &#39;name&#39;, 
   dataObj: data
  }
 }">
</router-link>

 1. path -> 是要跳转的路由路径,也可以是路由文件里面配置的 name 值,两者都可以进行路由导航
 2. params -> 是要传送的参数,参数可以直接key:value形式传递
 3. query -> 是通过 url 来传递参数的同样是key:value形式传递

 // 2,3两点皆可传递

2, $router way to jump

// 组件 a
<template>
 <button @click="sendParams">传递</button>
</template>
<script>
 export default {
 name: &#39;&#39;,
 data () {
  return {
  msg: &#39;test message&#39;
  }
 },
 methods: {
  sendParams () {
  this.$router.push({
   path: &#39;yourPath&#39;, 
   name: &#39;要跳转的路径的 name,在 router 文件夹下的 index.js 文件内找&#39;,
   params: { 
    name: &#39;name&#39;, 
    dataObj: this.msg
   }
   /*query: {
    name: &#39;name&#39;, 
    dataObj: this.msg
   }*/
  })
  }
 },
 computed: {

 },
 mounted () {

 }
 }
</script>
<style scoped></style>
----------------------------------------
// 组件b
<template>
 <h3>msg</h3>
</template>
<script>
 export default {
 name: &#39;&#39;,
 data () {
  return {
  msg: &#39;&#39;
  }
 },
 methods: {
  getParams () {
  // 取到路由带过来的参数 
  let routerParams = this.$route.params.dataobj
  // 将数据放在当前组件的数据内
  this.msg = routerParams
  }
 },
 watch: {
 // 监测路由变化,只要变化了就调用获取路由参数方法将数据存储本组件即可
  &#39;$route&#39;: &#39;getParams&#39;
 }
 }
</script>
<style scoped></style>
