title: Get column values from the selected rows
body: <p>When using <a href="http://www.datatables.net" rel="nofollow">DataTables</a> how do I get column values for the rows returned by fnGetNodes? I'm  using the function below that returns the selected rows. I want to use the return value of this function to delete the selected rows from the database. However, to do that I need the uniqueid value of each selected row. One other potential problem is that the uniqueid attr is marked with: </p>
  
  <blockquote>
    <p>bVisible: false</p>
  </blockquote>
  
  <p>so that it isn't actually displayed to the user as it is of no interest to them.</p>
  
  <pre><code>/* Get the rows that are selected */
  function fnGetSelected( oTableLocal )
  {
      var aReturn = new Array();
      var aTrs = oTableLocal.fnGetNodes();
  
      for ( var i=0 ; i&lt;aTrs.length ; i++ )                                       
      {
          if ( $(aTrs[i]).hasClass('row_selected') )
          {
              aReturn.push( aTrs[i] );
          }
      }
      return aReturn;
  }
  </code></pre>
