Couple of issues here.
Do you really want the entire 'query' variable inside your URL? That seems
weird, especially as you're also submitting it as one of the POST variables.
But the main problem is that your JS submit function doesn't return false,
so it doesn't cancel the default submission action: so your JS starts to
run, then the form submits via the normal HTTP POST, and the page is
refreshed.
function addClickHandlers() {
$("#submit").click( function() {
submit_form();
return false;
});
}
