Hello, I have a weird problem that seems way over my skill level so could use even some simple suggestions to point me in the right direction. I have a set of 6 chained dropdown menus that work fine on my computer, but do not retain the correct selections if I make the menu selections too quickly on the Heroku server.
Each time a selection is made from a dropdown, the session data is updated with the following jQuery/ Ajax: # If BOOK dropdown clicked on. chapters = $('#chapters').html() $('#books').change -> book = $('#books :selected').text() book_id = $('#books :selected').val() escaped_book = book.replace(/([ #;&,.+*~\':"!^$[\]()=>|\/@])/g, '\\$1') options = $(chapters).filter("optgroup[label='#{escaped_book}']").html() options = options.replace('selected="selected"', "") options = ('<option value="">Select a Chapter</option>' + options) $.ajax( url: '/dropdowns/update_image_book', data: "image_book_id=" + book_id) if options $('#chapters').html(options) $('#chapters').prop('disabled', false) $('#sections').html('<option value="">Select a Section</option>') $('#sections').prop('disabled', true) $('#subsections').html('<option value="">Select a Subsection</option>') $('#subsections').prop('disabled', true) $('#minisections').html('<option value="">Select a Topic</option>') $('#minisections').prop('disabled', true) else $('#chapters').empty() Here is controller: def update_image_book session[:image_book_id] = params[:image_book_id] session[:image_chapter_id] = "" session[:image_section_id] = "" session[:image_subsection_id] = "" session[:image_minisection_id] = "" redirect_to pictures_path end And the view: <%= select_tag :books, option_groups_from_collection_for_select(Subject.order(:title), :books, :title, :id, :title, get_id_from_session(:book)), :prompt => "Select a Book", :disabled => true %> After looking at the heroku logs, it looks like if I make the selections too quickly, the most recent selection runs before the line 2013-12-16T15:54:23.707522+00:00 heroku[router]: at=info method=GET path=/dropdowns/update_image_book?image_book_id=3 host=cryptic-mesa-2105.herokuapp.com fwd="75.118.31.205" dyno=web.1 connect=13ms service=32ms status=302 bytes=113 has a chance to run. Is this possible, and if so is there a better way to do this?
