filtering - jQuery dataTables - Clear search on a column -

looking @ example, http://www.datatables.net/examples/api/multi_filter_select.html, uses columns.search() datatable api, how 'clear' search , show results again when user selects 'all' or empty first option?

you clear search using empty string search term, without regular expression match. individual column filtering demo somehow little bit misleading, since first (unnamed) option not "all" or "any", 1 belive, in fact should named "empty" or "null". if select first option, regular expression search empty string performed. guess demo made in haste.

modified demo selecting first option "clear" search, selecting :

$("#example tfoot th").each( function ( ) {   var select = $('<select><option value="">all</option></select>')     .appendto( $(this).empty() )     .on( 'change', function () {        var term =  $(this).val()!='' ? '^'+$(this).val()+'$' : '';        table.column( )           .search(term, true, false )           .draw();        } );    table.column( ).data().unique().sort().each( function ( d, j ) {     select.append( '<option value="'+d+'">'+d+'</option>' )   }); });
