Update DataTables cached data from the DOM

  • Author: Lior Gerson
  • Deprecated: This plug-in has been deprecated and replaced with other functionality. Please see the detailed description below for more information.

Update the internal data for a tr element based on what is used in the DOM. You will likely want to call fnDraw() after this function.

DataTables 1.10+ has this ability built-in through the row().invalidate() method. As such this method is marked deprecated, but is available for use with legacy version of DataTables. Please use the new API if you are used DataTables 1.10 or newer.

Plug-in code

jQuery.fn.dataTableExt.oApi.fnDataUpdate = function ( oSettings, nRowObject, iRowIndex )
    jQuery(nRowObject).find("TD").each( function(i) {
          var iColIndex = oSettings.oApi._fnVisibleToColumnIndex( oSettings, i );
          oSettings.oApi._fnSetCellData( oSettings, iRowIndex, iColIndex, jQuery(this).html() );
    } );


This plug-in is available on the DataTables CDN:


Note that if you are using multiple plug-ins, it is beneficial in terms of performance to combine the plug-ins into a single file and host it on your own server, rather than making multiple requests to the DataTables CDN.
