Hi,

I'm working on a ruby on rails project. In a particular view page, I have used jQuery. This page has a table with (say ) 10 columns. Initially only 5 columns is show and rest are hidden. For hiding columns I have used jQuery. I have included jquery-rails gem jquery-ui gem and all necessary changes to be done in application.js is done. But if I do not add
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.12.0/jquery.min.js"></script>

hiding is not working. I have added code snippet below.
PS added javascript inside head element; using turbolinks
If I remove jquery link ; hiding is not working.

Can anyone solve the below issue ? Thanks

What I have tried:

JavaScript

<html>
<head>

     <script src="https://ajax.googleapis.com/ajax/libs/jquery/1.12.0/jquery.min.js"></script>
     
      <script type="text/javascript">
         $(document).ready(function(){

                 // to hide the week cols initially


                  <%  @colwno.each do |s|%> 
                        $('td:nth-child(<%=s%>)').hide();
                        $('#try1 th:nth-child(<%=s%>)').hide();
                       
                   <% end %>

      </script>

Hi, my application.js looks something like this:
//= require jquery
//= require jquery.purr
//= require jquery_ujs
//= require best_in_place
//= require jquery-ui
//= require best_in_place.jquery-ui
//= require best_in_place.purr
//= require turbolinks
..
//= require moment
//= require_tree .

Is the problem because ruby code is used inside javascript ?
