javascript - Jquery Datatable search -

-

i've created datatable using jquery datatable.

 $('#mytable').datatable({     "pagingtype": "simple_numbers",     "blengthchange": false,     "idisplaylength": 10,     "aasorting": [[0, 'asc']],     "processing": true,     "serverside": true,     "ajax": $('#mytable').data('source'),     "aocolumndefs": [         {'bsortable': false, 'atargets': [3, 4]}     ] });

but how can search on data displayed on table?

var datatable = $('#mytable').datatable();    $('#yourinputfieldid').on('input keyup paste', function () {     datatable.fnfilter(this.value);   });

// prevent submit on enter need prevent default behaviour of enter key on keydown event

$('#yourinputfieldid').keydown(function (event) {     if (event.keycode === 13) {       event.preventdefault();       return false;     }   });
