How can I set active tab by mixing in jQuery.localStorage variable in a rails erb condition?

gistfile1.txt

<ul class="nav nav-tabs">
  <% @booking.booked_rooms.each_with_index do |booked_room, index| %>
    <li class=""><a href="#room-<%= index %>" data-toggle="tab"><%= booked_room.door.title %></a> </li>
  <% end %>
</ul>

<script type="text/javascript" >

$(".nav-tabs").on('click', function(e) {
  localStorage.setItem( 'booking-tab',$('.nav-tabs .active').find("a").attr("href") );
});

</script>
