Change an option of a select according to the choice of another select (HTML form)

Question

Hey, here’s the thing.

I have an area of a form in which I select the code of the company, company and also show the taxation of that company.

I will show the image of the fields: (my problem is in the part marked in red)

COD and Enterprise are listed dynamically via PHP and AJAX with a query in the database that lists companies that are the responsibility of the logged-in user. And the Taxation is shown according to the Taxation of the company (Each company can have 5 types of Taxation).

I would like the following, when I changed the COD, the Company corresponding to that Code and its Taxation were changed in select automatically.

And I would also like to see the same thing done when I changed the Company. COD and Taxation were also changed.

Remember that all these data are linked to the same Mysql table. And they are all linked to each other.

I managed to make a "Gambi" in which I almost resolve that situation. When I change the COD, the company and the corresponding Taxation are also changed. However, it is not the same when I change the company. The only thing that changes is taxation.

Note: COD and Companies are <select> and Taxation is a <input type="text">.

I’ll leave my code here (with the "Gambi") to see if you can help me.

    var trib = $("select#codigo-empresa option:selected").attr('name');
    $("input[id='tributacao']").val(trib);

  });
});
