filter save widget

[Benni-chan]

Hi,
since there was no way to save a filter (like the savesort widget), i wrote my own little widget. maybe it is of some use to you.

$.tablesorter.addWidget({
    id: 'FilterSave',
    format: function(table, init){
        var sl, time, c = table.config,
            wo = c.widgetOptions,
            ss = wo.FilterSave !== false; // make FilterSave active/inactive; default to true

        var count_filters = $(table).find('input.tablesorter-filter').length;
        var filter = new Array();
        for (var i=0; i<count_filters;i++)
        {
            filter[i]=$(table).find('input.tablesorter-filter').eq(i).val();
        }

        if (c.debug){
            time = new Date();
        }
        if ($(table).hasClass('hasSaveFilter')){
            if (ss && table.hasInitialized && $.tablesorter.storage){
                $.tablesorter.storage( table, 'tablesorter-savefilter', filter );
                // console.log("saved"+filter)
                if (c.debug){
                    $.tablesorter.benchmark('FilterSave widget: Saving last filter: ' + filter, time);
                }
            }
        } else if (table.hasInitialized){
            // set table sort on initial run of the widget
            $(table).addClass('hasSaveFilter');
            filter = '';
            // get data
            if ($.tablesorter.storage){
                fl = $.tablesorter.storage( table, 'tablesorter-savefilter' );
                filter = (fl && $.isArray(fl)) ? fl : '';
                if (c.debug){
                    $.tablesorter.benchmark('FilterSave: Last filter loaded: "' + filter + '"', time);
                }
            }
            // init is true when widget init is run, this will run this widget before all other widgets have initialized
            // this method allows using this widget in the original tablesorter plugin; but then it will run all widgets twice.
            if (filter && filter.length > 0)
            {
                $(table).trigger('search', [filter]);
            }
        }
    },
    remove: function(table, c, wo){
        // clear storage
        $.tablesorter.storage( table, 'tablesorter-savefilter', '' );
    }
});
