Question

Ok so hoping this is final question on Bootstrap Scrollspy, almost there, one more problem to fix i hope. As I have read having a body of 100% seems to disagree with scrollspy ( Im using sticky footer). The final element in my nav is highlighted no matter where i am on the page.

I have tried removing 100% body
I have tried removing the scrollspy js
I have tried setting the body as the target element
I have tried $('body').scrollspy();

None of these work. If i set the height though on the element I am spying on then it does work, though it seems to scroll past the target element quite a bit and then change. I would like to still be able to keep sticky footer.

Here is my code

View

<div class="container">
 <div class="row show-grid clear-both">
  <div id="left-sidebar" class="span3 sidebar">
    <div class="side-nav sidebar-block">
     <div id="dateNav">
      <h3 class="resultTitle fontSize13">Release Dates</h2>
       <ul class="nav date">
        <% @response.each_pair do |date, movie| %>
        <li><i class="icon-chevron-right"></i><%= link_to date_format(date), "#d_#{date}", :id=> '#d_#{date}' %></li>
        <% end %>
      </ul>
     </div>
    </div>
  </div>
<div class="span9">
  <div id="spyOnThis" data-spy="scroll" data-target="#dateNav">
   <% @response.each_pair do |date, movie| %>
    <h3 class="resultTitle fontSize13" id="d_<%= date %>">Available on&nbsp;<%= date_format(date) %></h3>
    <% movie.each do |m| %>
      <div class="thumbnail clearfix">
        <!--Image here
    <% end %>>
        <div class="caption pull-right">
          <!--Content Here
        </div>
      </div>
    <% end %>
  <% end %>
  </div>
</div><!--span9-->
</div><!--Row-->
</div><!--/container-->

JS

$('#dateNav').scrollspy();

CSS

#dateNav{
position: fixed;
}

#spyOnThis {
height:100%;
overflow:auto;
}

.side-nav .active a {
 color: #FFBE00;
}

HTML Output (Nav)

  <div id="left-sidebar" class="span3 sidebar">
   <div class="side-nav sidebar-block">
    <div id="dateNav">
     <h3 class="resultTitle fontSize13">Release Dates</h3>
     <ul class="nav date">
    <li><i class="icon-chevron-right"></i>
    <a id="#d_#{date}" href="#d_2013-01-09">9th Jan 2013</a>

  </li>
  </ul>
  </div>

Element being spied on

<div class="span9">
 <div id="spyOnThis" data-target="#dateNav" data-spy="scroll">

  <h3 id="d_2013-01-09" class="resultTitle fontSize13">Available on 9th Jan 2013</h3>
   <div class="thumbnail clearfix">
    <!--Image Here -->
    <div class="caption pull-right">
     <!--Paragraphs in here -->
    </div>
   </div>

    <h3 id="d_2013-01-11" class="resultTitle fontSize13">Available on 11th Jan 2013</h3>
     <div class="thumbnail clearfix">
    <!--Image Here -->
     <div class="caption pull-right">
    <!-Paragraphs here
     </div>
    </div>

     <div class="thumbnail clearfix">
      <!-- Image Here-->
      <div class="caption pull-right">
       <!-paragraphs here -->
      </div>
    </div>

     <div class="thumbnail clearfix">
      <!-- Image Here-->
      <div class="caption pull-right">
       <!-paragraphs here -->
      </div>
    </div>

     <h3 id="d_2013-01-09" class="resultTitle fontSize13">Available on next date</h3>
   <div class="thumbnail clearfix">
    <!--Image Here -->
    <div class="caption pull-right">
     <!--Paragraphs in here -->
    </div>
   </div>
   </div>
   </div>

Apologies for the amount of code but better to have more on there i guess

So does anyone know of a solution for this as scrollspy does seem quite buggy at the moment

Thanks

Answer 1

You simply can’t set 100% height on the element you’re spying on with ScrollSpy, whether it be body or another div.
However, there is an issue on GitHub that suggests a workaround for this (also discussed here).

In your case, this would be:

$(window).scrollspy({wrap: $('#spyOnThis')[0]});

Here’s a jsFiddle of your code that works with that fix. Note that I changed some of your HTML:

• I removed the data-target and data-spy attributes again. When initiating ScrollSpy, use either the data attributes or the JavaScript.
• I gave your span9 div the #spyOnThis ID, since the extra markup was unnecessary.

Hopefully this will resolve it once and for all.

EDIT

This solution worked; for @Richlewis’ specific scenario we needed to add the parameter offset: -250 to ScrollSpy.
