So I have a vue project with a dashboard that contains many tests and i want to pass the test name as a parameter in an axios request when the user clicks on a button and gets redirected on another page.

I already did the first part and passed the name of the test in route as a parameter name and now i'm trying to fetch the corresponding item in the collection.When using $route.params.name I get an error that says $route is not defined here's my code so far

<template>
  <v-app>
           
    <app-navbar />

    <v-main>
      <div >
      <h3>
        test {{ $route.params.name }}, {{ $route.query.status }},{{
          $route.query.tag
        }}
      </h3>
      <h3 v-if="this.loadAPI">{{failreason()}}</h3>
      </div>

  
        <v-data-table
    :headers="headers"
    :items="imagesref"
    :items-per-page="5"
    
  >
  <template v-slot:[`item.index`]="{ index }">
     
        {{index 1}}
  </template>
  <template v-slot:[`item.status`]="{ index }">
     {{imagesresult[index][2]}}
        
 
  </template>
  
  <template v-slot:[`item.ref`]="{ index }">

CodePudding user response：

Globally injected properties in Vue are available from the Vue context, not the global javascript context (like window).

So, in the <script> tag, you have to use this.$router to access it.

In your created hook:

// replace
data: {name: $route.params.name}

//by
data: {name: this.$route.params.name}

From the vue-router docs:

By calling app.use(router), we get access to it as this.$router as well as the current route as this.$route inside of any component:
