How to get a domain variable value

Question

so I have a question, which maybe it's a little ez, but... I don't know hehe, so, how do you get a value that's in the domain? like:

https://example.com?test=helloworld

how do I get the value of the "test" variable that is there?

Do you mean `https://example.com/?test=helloworld`. Or is the missing `?` deliberate ? — Gabriele Petrioli, Dec 04 '21 at 23:48

You probably mean https://example.com?test=helloworld including a ?.

Reading Value from URL

const url = new URL('https://example.com?test=helloworld');

console.log(url.searchParams.get("test")); // prints: helloworld

And to get the current URL you can use window.location.href.

Add Value to URL

const url = new URL('https://example.com');

url.searchParams.append('test', 'helloworld');

console.log(url.href);  // prints: https://example.com?test=helloworld

Have a look at the URL API on the MDN documentation.
