body tag

<body data-spy="scroll" data-target=".stickysteps">

how scrollspy called

<% if manual.present? && manual.steps.present? %>  <div class="stickysteps"> <ul class="nav nav-pills">     <% n = 0 %>     <% @manual.steps.order(:priority).each |step| %>         <li><a href="#step<%= n+1 %>"><h4>step <%= n + 1 %></h4></a></li>         <% n += 1 %>     <% end %> </ul> </div> <h1 style="margin-left: 20px;">your instructions:</h1> </br> <% steps = manual.steps.order(:priority) %> <%= render(steps.order(:priority), steps: steps) %> <% end %>  <script type="text/javascript"> $('.stickysteps').scrollspy();  $('[data-spy="scroll"]').each(function () { $('.stickysteps').scrollspy('refresh'); });  offsetvalue = 168; $('body').data().scrollspy.options.offset = offsetvalue; // force scrollspy recalculate offsets targets $('body').data().scrollspy.process(); </script>  <%= javascript_include_tag "manuals" %> <%= javascript_include_tag "imagezoom" %>
