Uncaught TypeError: Object [object Object] has no method 'fnFilter'

$(document).ready(function () {

var selectedColumn = $('#columnlist').find(":selected").text();

$('#csearchtext').bind("change paste keyup", function () {
    var input = $('#csearchtext').val();

    console.log(input);

    $('#table_id').fnFilter('',4);
});

$('#dblist').on('change', function () {

    var selected = $('#dblist').find(":selected").text();
    tablefill(selected);

});

$('#search').click(function () {

    var selected = $('#dblist').find(":selected").text();
    tablefill(selected);

});

function tablefill(selected) {
    $('.advsearchbar').show();
    $('#stable').show();

    $('#table_id').dataTable({

});

Uncaught TypeError: Object [object Object] has no method 'fnFilter' I am not sure why this is happening the jquery is included because the datatable is being created just fine. Any help on this will be great.

Answer 1

您必须像这样链接dataTable对象。

$('#table_id').dataTable().fnFilter('', 4);

Answer 2

You need to get the dataTable object, instead of the jQuery object.

$('#table_id').dataTable().fnFilter('',4);

From the docs:

$(document).ready(function() {
  var oTable = $('#example').dataTable();

  // Sometime later - filter...
  oTable.fnFilter( 'test string' );
} );
