How can I extract URL parameters in Vue.js using a JavaScript file?

Question

How can I extract URL parameters in Vue.js using a JavaScript file?

Currently, I have a URL: http://local-pr.local?id=12

Within the file page.vue:

Upon using:
```
console.log(this.$route.query.id)
```
, I successfully retrieve the value.

Now, my objective is to access this parameter in the file: page.js

import addon from './addon'
import user from './user'

// My intention is to verify if there is a new 'id' parameter that needs to be exported.
if (this.$route.query.id) {
   export default [...addon, ...user]
}

```
console.log(this.$route.query.id)
```

However, an ERROR occurs: Reason: TypeError: Cannot read properties of undefined (reading '$route')

I am seeking guidance on how to retrieve parameters in a JavaScript file. Any insights or experiences would be greatly appreciated. Thank you!

Answer №1

One way to approach this is by creating a function that accepts the $route as an argument:


import addon from './addon'
import user from './user'

export default function checkParams(route) {
   if(this.$route.query.id){
    return [...addon, ...user]
  }
}

Then, you can use this function in any component like so:

import checkParams from './page.js'

.....

let data = checkParams(this.$route)
