Based on fact that this is GET parameter you can do it like that:
(function() {
var url_string = window.location.href;
var url = new URL(url_string);
var editors = url.searchParams.get('editors');
var htmlElement = document.getElementById("element");
htmlElement.innerHTML += editors;
})();
Where in your case your searchParams is n.
After you get this element you can easily append your html code.
EDIT I've added example with appending html element.
