If you want a really simple way to preserve the query string and possibly append to it, use window.location.search; here's a snippet:

var search = window.location.search + (window.location.search ? "&" : "?");
                search += "param1=foo¶m2=bar";
                window.location.href = window.location.protocol + "//" + window.location.host + window.location.pathname + search;

You can, of course, use a more sophisticated way of building the rest of your query string, as found in the other examples, but the key is to leverage Location.search.
