How to use router to pass parameters in Vue.js

This time I will show you how to use the router in Vue.js to pass parameters. What are the precautions when using the router in Vue.js to pass parameters. The following is a practical case, let's take a look.

Vue-router parameter passing

Why do we need to pass parameters in the router

Imagine a scenario. Currently on the homepage, you need to click on a certain item to view detailed information about the item. Then at this time, you need to pass the id of the item to the details page on the home page, and the details page can obtain the detailed information through the id.

Parma passing parameter

Post code:

/ router/index.vue

export default new Router({
 routes: [
  {
   path: '/',
   name: 'Home',
   component: Home
  },
  {
   path: '/work',
   name: 'Work',
   component: Work
  }
 ]
  })

The component Works passes a work id to the component Work

/components/Home/Comtent/Works.vue

// 触发它传递一个对象到组件Work
getIt (id) {
 this.$router.push({
  path: '/work',
  name: 'Work',
  params: {
   id: id
  }
 })
  }

/components/Work/ Index.vue

<template>
  <p>
   work: {{id}}
  </p>
 </template>
 
 <script>
 export default {
  name: &#39;Work&#39;,
  data () {
   return {
    id: this.$route.params.id //拿到id
   }
  }
 }
 </script>

##query parameter

Just change the above parmas to query, that is:

// 传入
 this.$router.push({
path: '/work',
name: 'Work',
query: {
 id: id
}
 })
 
 ... ...
 
 this.$route.query.id // 获取

The difference between parmas and query

query passes parameters through the url and is always displayed in the url

parmas transfer parameters, there will be no data after refreshing the page, and the obtained parameters cannot be saved
