compare query string with inputed information based on a json file

I'm using BootstrapVue - I open my localhost with a URL + query string key. Now I want to check if the key of my query string is equal to my key in the json data, based on my input ID.

So I need these steps:

1. Get key of query string (this one is this.key as you can see in my mounted() )
2. Get key of my inputed ID, based on the json file
3. Compare them and return that my button can be clicked (if they match)

So my goal is following: The button will only enabled if the key of my json based on the inputed ID is equal to my key of the query string.

My URL to open localhost: http://localhost:8080/?key=RxGxQZuLjGhFcdtQctJfcJejRPwEPety
