Using a dropdown list to filter a table (dataTables)

I'm using the dataTables jQuery plugin (which is totally awesome), but I'm having trouble getting my table to filter based on the change of my select box.

Function:

  $(document).ready(function() {
      $("#msds-table").dataTable({
        "sPaginationType": "full_numbers",
        "bFilter": false
       });

      var oTable;
      oTable = $('#msds-table').dataTable();

      $('#msds-select').change( function() { 
            oTable.fnFilter( $(this).val() ); 
       });
   });

HTML:

  <table border="0" cellpadding="0" cellspacing="0" id="msds-table">
                    <thead>
                      <tr>
                        <th>Column 1</th>
                        <th>Column 2</th>
                        <th>etc</th>
                      </tr>
                    </thead>
                    <tbody>
                    <select id="#msds-select">
                    <option>All</option>
                    <option>Group 1</option>
                    <option>Group 2</option>
                    <option>Group 3</option>
                    <option>Group 4</option>
                    <option>Group 5</option>
                    <option>Group 6</option>
                    </select>
                    <tr class="odd">
                        <td>Group 1</td>
                        <td><img src="images/modules/download-icon.gif" width="12" height="17" alt="" /></td>
                        <td><a href="#">Download</a></td>
                    </tr>
                    <tr class="even">
                        <td>Group 1</td>
                        <td><img src="images/modules/download-icon.gif" width="12" height="17" alt="" /></td>
                        <td><a href="#">Download</a></td>
                    </tr>
                    <tr class="odd">
                        <td>Group 1</td>
                        <td>开发者_开发技巧<img src="images/modules/download-icon.gif" width="12" height="17" alt="" /></td>
                        <td><a href="#">Download</a></td>
                    </tr>
     </tbody>
 </table>

Table goes on to display a bunch of items, up to "Group 6", but you get the idea. Anyone ever tried to do this before?

dataTables features

I knew I had done this before, and you have to watch this little piece of information:

Note that if you wish to use filtering in DataTables this must remain 'true' - to remove the default filtering input box and retain filtering abilities, please use sDom.

you need to set {bFilter:true}, and move your <select></select> into a custom element registered through sDom. I can guess your code will look like this:

$(document).ready(function() {
      $("#msds-table").dataTable({
        "sPaginationType": "full_numbers",
        "bFilter": true,
        "sDom":"lrtip" // default is lfrtip, where the f is the filter
       });
      var oTable;
      oTable = $('#msds-table').dataTable();

      $('#msds-select').change( function() { 
            oTable.fnFilter( $(this).val() ); 
       });
   });

your code for oTable.fnFilter( $(this).val() ); will not fire while {bFilter:false}; according to the documentation

   $.extend( true, $.fn.dataTable.defaults, {
            "bFilter": true,
                initComplete: function () {
                    this.api().column(1).every( function () {
                        var column = this;
                        var select = $('<select><option value="">All Subjects</option></select>')
                            .appendTo( $(column.header()).empty() )
                            .on( 'change', function () {
                                var val = $.fn.dataTable.util.escapeRegex($(this).val());
                                column
                                    .search( val ? '^'+val+'$' : '', true, false )
                                    .draw();
                            } );
                        column.data().unique().sort().each( function ( d, j ) {
                            select.append( '<option value="'+d+'">'+d+'</option>' )
                        } );
                    } );
                },
        } );

Use this code:

 $('.btn-success').on('click',function (e) {
               //to prevent the form from submitting use e.preventDefault()
                e.preventDefault();
                var res = $("#userid").val();  
                var  sNewSource = "<?php echo base_url(); ?>myaccount/MyData_select?userid=" + res + "";
                var oSettings = ETable.fnSettings();
                oSettings.sAjaxSource  = sNewSource;
                ETable.fnDraw();
            });
