filtertablesorter

Is there a way in tablesorter to filter to select only rows where the field is empty?


When I use '|Empty' in filter_functions no filtering is applied. I'd like to be able filter so that rows where the field is empty are shown.


Solution

  • I just updated the tablesorter fork repository, so with v2.21.5+, you can now add a filter_function to target empty cells, and use the filter_selectSource to populate the select with custom and/or all column cell text as options (demo):

    $(function(){
        $('table').tablesorter({
            theme: 'blue',
            widgets: ['zebra', 'filter'],
            widgetOptions: {
                filter_functions: {
                    0: {
                        '{empty}' : function (e, n, f, i, $r, c) {
                            return $.trim(e) === '';
                        }
                    }
                },
                filter_selectSource: {
                    0: function (table, column, onlyAvail) {
                        // get an array of all table cell contents for a table column
                        var array = $.tablesorter.filter.getOptions(table, column, onlyAvail);
                        // include the filter_function option
                        array.push('{empty}');
                        return array;
                    }
                }
            }
        });
    
    });
