Can datatables sort a column with an input field?

Question

I am trying to make datatables sort my columns. The first column works okay as it\'s a simple number. However the next column is an input field. When I try to make that sort

Answer 1

jQuery.fn.dataTableExt.oSort['textbox-asc'] = function (a, b) {
    var vala = $('#' + $(a).filter('input').attr('id')).val().toLowerCase();
    var valb = $('#' + $(b).filter('input').attr('id')).val().toLowerCase();
    if (vala === '')
        return 1;
    if (valb === '')
        return -1;
    return vala < valb ? -1 : vala > valb ? 1 : 0;
};

jQuery.fn.dataTableExt.oSort['textbox-desc'] = function (a, b) {
    var vala = $('#' + $(a).filter('input').attr('id')).val().toLowerCase();
    var valb = $('#' + $(b).filter('input').attr('id')).val().toLowerCase();
    if (vala === '')
        return 1;
    if (valb === '')
        return -1;
    return vala < valb ? 1 : vala > valb ? -1 : 0;
};

then use it like this

 $(datatable).dataTable({
                    "iDisplayLength": 50,
                    "bLengthChange": false,
                    "bPaginate": false,                        
                    "columns": [
                        null, { "sType": "textbox" }
                    ],
                });
