disable pagination if there is only one page in datatables

I am implementing datatbales and according to my requirement, most of the things have been resolved except the pagination issue. In my case for every time pagination navigation is displaying. I want to disable the pagination navigation if there is only one page at all.How to do that? My code is like:

JS

<script>
  function fnFilterColumn(i) {

    $('#example').dataTable().fnFilter(
      $("#col" + (i + 1) + "_filter").val(),
      i
    );
  }
  $(document).ready(function() {


    $('#example').dataTable({
      "bProcessing": true,
      "sAjaxSource": "datatable-interestdb.php",
      "bJQueryUI": true,
      "sPaginationType": "full_numbers",
      "sDom": 'T<"clear">lfrtip',
      "oTableTools": {
        "aButtons": [

          {
            "sExtends": "csv",
            "sButtonText": "Save to CSV"
          }
        ]
      },
      "oLanguage": {
        "sSearch": "Search all columns:"
      }


    });


    $("#example").dataTable().columnFilter({
      aoColumns: [
        null,
        null,
        null,
        null
      ]
    });


    $("#col1_filter").keyup(function() {
      fnFilterColumn(0);
    });

  });
</script>

HTML

<table cellpadding="3" cellspacing="0" border="0" class="display userTable" aria-describedby="example_info">

  <tbody>
    <tr id="filter_col1">
      <td>Interest:</td>
      <td>
        <input type="text" name="col1_filter" id="col1_filter">
      </td>
    </tr>
  </tbody>
</table>


<table width="100%" border="0" align="center" cellpadding="2" cellspacing="1" class="form_table display" id="example">

  <thead>
    <tr>
      <th class="sorting_asc" width="25%">Interest</th>
      <th width="25%">Name</th>
      <th width="25%">Email</th>
      <th width="25%">Contact No</th>
    </tr>
  </thead>
  <tbody>

    <tr>
      <td colspan="4" class="dataTables_empty">Loading data from server</td>
    </tr>
  </tbody>
  <tfoot>
    <tr>
      <th></th>
      <th></th>
      <th></th>
      <th></th>
    </tr>
  </tfoot>


</table>

Solution 1:

Building off of Nicola's answer, you can use the fnDrawCallback() callback and the oSettings object to hide the table pagination after it's been drawn. With oSettings, you don't need to know anything about the table settings (records per page, selectors specific to the table, etc.)

The following checks to see if the per-page display length is greater than the total records and hides the pagination if it is:

$('#your_table_selector').dataTable({
    "fnDrawCallback": function(oSettings) {
        if (oSettings._iDisplayLength > oSettings.fnRecordsDisplay()) {
            $(oSettings.nTableWrapper).find('.dataTables_paginate').hide();
        } else {
             $(oSettings.nTableWrapper).find('.dataTables_paginate').show();
        }
    }
});

• fnDrawCallback()
• oSettings

Solution 2:

You must hide them dynamically I think, you can use fnDrawCallback()

$('#example').dataTable({
    "fnDrawCallback": function(oSettings) {
        if ($('#example tr').length < 11) {
            $('.dataTables_paginate').hide();
        }
    }
});​

EDIT - another way found here could be

"fnDrawCallback":function(){
      if ( $('#example_paginate span span.paginate_button').size()) {
      $('#example_paginate')[0].style.display = "block";
     } else {
     $('#example_paginate')[0].style.display = "none";
   }
}

Solution 3:

See my feature plugin conditionalPaging.

Usage:

$('#myTable').DataTable({
    conditionalPaging: true
});

or

$('#myTable').DataTable({
    conditionalPaging: {
        style: 'fade',
        speed: 500 // optional
    }
});
