Answer 1

If you want to learn rails way ajax submit on fields change here is the code.

<%= select_tag(:id, options_from_collection_for_select(active_cars, "id", "name"), 
data: { remote: true, url: your_ajax_route_path }%><%= submit_tag "Switch Car" %>

data: { remote: true, url: your_ajax_route_path }

will automatically submit your input to your_ajax_route_path. If you are using a form builder then you should use with input_html

input_html: { data: { remote: true, url: your_ajax_route_path } }

like this. I hope it'll be useful for you
