I have a button that apply filter to jquery datatable
$(\"#buttonFilter\").button().click(function() { if (lboxColor.val() != null) {
For datatables 1.9 and later this solution works:
myDataTableHandle = $('#example1').dataTable(...); ... ... var myFilteredRows = myDataTableHandle._('tr', {"filter":"applied"});
and you won't have to include a separate api plugin. :)
