With jQuery, use serialize() the form and post it to your route.

$('#form').submit(function(e) {

    e.preventDefault();
    var url = "{{ path('YOUR_PATH') }}";
    var formSerialize = $(this).serialize();
    
    $.post(url, formSerialize, function(response) {
        //your callback here
        alert(response);
    }, 'JSON');
});

In your action

if ($form->isSubmitted() && $form->isValid()) {

....

  // or return new JsonResponse($anyData);
  return new Response(json_encode(['status'=>'success']));
}

it must be ok like this. but you can add some parameters like the format, methods etc... in your routing.
