$((function () {
    'use strict';
    MyUSJ.tableLiveFilter = {
        init: function (config) {
            this.config = config;
            this.bindEvents();
        },
        bindEvents: function () {
            this.config.searchInput.on('keyup search', this.filter);
        },
        filter: function () {
            var self = MyUSJ.tableLiveFilter,
                $this = $(this),
                searchTableTr = self.config.searchTable.find('tbody>tr');

            if ($this.val() !== '') {
                searchTableTr.hide();
                self.config.searchTable.find('td:contains-ci(\'' + $this.val() + '\')').parent('tr').show();
            } else {
                searchTableTr.show();
            }
        }
    };
}()));

$.extend($.expr[':'], {
    'contains-ci': function (elem, i, match, array) {
        'use strict';
        return (elem.textContent || elem.innerText || $(elem).text() || '').toLowerCase().indexOf((match[3] || '').toLowerCase()) >= 0;
    }
});
