Unable to install fnGetHiddenNodes API plugin

PaoloValladolid

I added this line to my JSPX file, as instructed here: http://datatables.net/plug-ins/api#fnGetHiddenNodes



I got an "Object doesn't support this property or method" error message upon load of the page.

Is fnGetHiddenNodes provided in another .js file? I searched jquery.dataTables.js and was unable to find fnGetHiddenNodes there

Bump - still very much need this information. The instructions do not work for me, as previously stated.

Hi PaoloValladolid,

Did you save the fnGetHiddenNodes plug-in into the file you are including? The easiest way is like this example: http://datatables.net/examples/plug-ins/plugin_api.html

Hi Allan,

So the solution would be to copy the following function into my copy of jquery.dataTables.js?

$.fn.dataTableExt.oApi.fnGetHiddenTrNodes = function ( oSettings )
{
/* Note the use of a DataTables 'private' function thought the 'oApi' object */
var anNodes = this.oApi._fnGetTrNodes( oSettings );
var anDisplay = $('tbody tr', oSettings.nTable);

/* Remove nodes which are being displayed */
for ( var i=0 ; i

The easiest is like in the demo example linked above:

[code]


/*
* Function: fnGetHiddenTrNodes
* Purpose: Get all of the hidden TR nodes (i.e. the ones which aren't on display)
* Returns: array:
* Inputs: object:oSettings - DataTables settings object
*/
$.fn.dataTableExt.oApi.fnGetHiddenTrNodes = function ( oSettings )
{
/* Note the use of a DataTables 'private' function thought the 'oApi' object */
var anNodes = this.oApi._fnGetTrNodes( oSettings );
var anDisplay = $('tbody tr', oSettings.nTable);

/* Remove nodes which are being displayed */
for ( var i=0 ; i
