jquery - Disable form button until all field are filled out rails 5.1 -


i have following form , looking solution disable button until form has field out. using rails 5.1, twitter bootsrap , jquery.

<div class="well"> <%= bootstrap_form_for @dup |f| %>  <% if current_user.errors.any? %>           <div id="error_explanation" class="errors">             <ul>             <% current_user.errors.full_messages.each |message| %>               <li><%= message %></li>             <% end %>             </ul>           </div>         <% end %>     <%= f.text_field :title, placeholder: "title here...", label: "title* (required)" %>     <%= f.text_field :company_name, placeholder: "company name here...", label: "company name* (required)" %>     <%= f.text_area :description, placeholder: "add description here...", label: "description* (required)" %>     <%= f.text_field :location, placeholder: "location here...", label: "location* (required)" %>     <%= f.collection_select :bus_id, bus.all, :id, :name, include_blank: 'select a', label: "a* (required)"%>     <%= f.label "needed" %>     <%= f.collection_check_boxes :dup_ids, dup.all, :id, :name, label: (fa_icon 'cogs-o 2x') %>     <%= f.fields_for :dups, @g.dups.build |dups_fields| %>       <%= skills_fields.text_field :name, label: "add here (optional)", placeholder: "add here..." %>     <% end %>     <%= f.url_field :url, placeholder: "http://...", label: "url (optional) - must start http://" %>     <%=  f.hidden_field :company_id, :value => current_user.id unless @job.company_id %>      <%= form_tag charges_path %>       <article>         <% if flash[:error].present? %>           <div id="error_explanation">             <p><%= flash[:error] %></p>           </div>         <% end %>         <label class="amount">           <span>amount: <%= pretty_amount(@amount) %></span>         </label>       </article>        <script src="https://checkout.stripe.com/checkout.js" class="stripe-button"               data-key="<%= rails.configuration.stripe[:publishable_key] %>"               data-description="a month's subscription"               data-amount="<%= @amount %>"               data-email="<%= current_user.email %>"               data-locale="auto"></script>     <% end %>      <%= f.submit class: "btn btn-primary btn-outline btn-sm" %>   <% end %> </div>

looking jquery solution. how can call rails form tag fields?

if add same class each of fields can count fields class , enable button once filled out:

<script type="text/javascript">     function checkform() {       var count = $('.checklist').filter(function() {         return $(this).val() !== "";       }).length;        var total = $('.checklist').length;        if (count == total) {         $('.submit-form').removeclass('disabled');         $('.submit-form').removeattr('disabled');           } else {         $('.submit-form').addclass('disabled');         $('.submit-form').attr('disabled', 'disabled');       }       console.log(count + '/' + total);     }      $('.checklist').on('keyup', checkform); </script>  <%= f.submit class: "btn btn-primary btn-outline btn-sm submit-form disabled", disabled: true %>

but if checkboxes might have adjust count function.
