  This is the code I used, taken from that stackoverflow question:

       "fnDrawCallback": function(oSettings) {
              if ($('#studyTable tr').length < 11) {
                  $('.dataTables_paginate').hide();
              }
              if ($('#studyTable tr').length >= 11) {
                  $('.dataTables_paginate').show();
              }
          }

  Use the rows() API along with the count() API, something like this:

   if (table.rows().count() < 11) {
          $('.dataTables_paginate').hide();
         } else {
          $('.dataTables_paginate').show();
         }
  

  The reason your code doesn't work is only the rows shown on the page are in the DOM.

  I'm not sure how to use that? I get the error Uncaught TypeError: $(...).rows is not a function

  I'm putting it in the callback like this:

  "fnDrawCallback": function(oSettings) {
                if ($('#studyTable').rows().count() < 11) {
         $('.dataTables_paginate').hide();
        } else {
         $('.dataTables_paginate').show();
        }

  You need an instance of the Datatables API. Try:
  $('#studyTable').DataTable().rows().count().

  Hm, that doesn't hide the pagination at all anymore, even when there are less than 11 rows

  The code seems to work here:

  The paging element is hidden. Comment out the first Datatable and uncomment the second and you will see that the paging element remains. If you still have issues please provide or update my test case to show the problem.

  Note the use of this.api() in drawCallback. You can access the API this way in most of the Datatables Callbacks.

  If you use the #example2 table in your test case and search for "Ramos", only one entry shows up in the table but the pagination still shows. This is my issue- I'm filtering the table and want the pagination not to show when there are fewer than 10 entries.

  You can use the selector-modifier of {search: 'applied'} with the rows() API, like this:

  Yep, it just needs the search filter to be considered when counting the rows, see here: http://live.datatables.net/nupokuse/5/edit
