For example I have this querystring www.meusite.com.br?parametro=1. I wanted to exchange the value 1 for another value when a given function is called, without having to load the page again (if possible).

To change the URL via javascript would be like this:
var Url = window.location.host;
document.location = Url + "?parametro=2"; //muda o valor de "parametro" para 2
However it is not possible to change the URL without re-loading the page, this is a security restriction.
Imagine that the user receives a fake email as if it were from a bank, clicks on a button and is sent to a fake page but soon after the URL is changed to the real address of the bank. The user fills in the login and via data ajax are recorded in a database and then redirects to a real page. It would be a serious security breach!
Although there are other ways to detect if the URL is false, most users do not know how to do it.

Filipe a doubt, and if for example, I already have the parameter = 1, and need to change to 2.... it will change the value or add a new parameter ?

It depends on what you do! In the example I gave changes the value because a concatenation is made with the URL.

So, but for example, assuming the url is
www.meusite.com.br?parametro=1and then I run your code, the url wouldn’t bewww.meusite.com.br?parametro=1¶metro=2? -
@Lucassousa no, it would be www.meusite.com.br? parametro=2, I made a change in the answer example, see if it now works.
