Jquery tablesorter how to store previous sort list

Jquery tablesorter how to store previous sort list

Hi i am using jquery tablesorter plagin. I want to store the previous sort list when a user close or make a refresh to the page. And after refresh or reload the page, the table will use the previously stored sort order. I try in many ways. Here is one of those:

  1. $.tablesorter.addWidget({
            // give the widget an id
            id: "sortPersist",
            // format is called when the on init and when a
            // sorting has finished
            format: function(table) {
         
              // Cookie info
              var cookieName = 'MY_SORT_COOKIE';
              var cookie = $.cookie(cookieName);
              var options = {path: '/'};
         
              var data = {};
              var sortList = table.config.sortList;
              var tableId = $(table).attr('id');
              var cookieExists = (typeof(cookie) != "undefined"
                  && cookie != null);
         
              // If the existing sortList isn't empty, set it into the cookie
              // and get out
              if (sortList.length > 0) {
                if (cookieExists) {
                  data = $.evalJSON(cookie);
                }
                data[tableId] = sortList;
                $.cookie(cookieName, $.toJSON(data), options);
              }
         
              // Otherwise...
              else {
                if (cookieExists) {
         
                  // Get the cookie data
                  var data = $.evalJSON($.cookie(cookieName));
         
                  // If it exists
                  if (typeof(data[tableId]) != "undefined"
                      && data[tableId] != null) {
         
                    // Get the list
                    sortList = data[tableId];
         
                    // And finally, if the list is NOT empty, trigger
                    // the sort with the new list
                    if (sortList.length > 0) {
                      $(table).trigger("sorton", [sortList]);
                    }
                  }
                }
              }
            }
    });


















































  2. $.tablesorter.addWidget({
        id: "numbering",
        format: function(table) {
            var c = table.config;
            $("tr:visible", table.tBodies[0]).each(function(i) {
                $(this).find('td').eq(0).text(c.page*c.size+i + 1);
            });
        }
    });







  3. $(document).ready(function()
            {
                try{
                $.tablesorterPager.defaults.size=document.getElementById("pagesize").value;
                $(".tablesorter").tablesorter(
                        {
                            widgets: ['numbering']
                        }
                        ).tablesorterPager({container: $("#pager")});
                }
                catch(e){}
                   
                $(".tablesorter").tablesorter({widgets: ['numbering', 'sortPersist']});
               
            }
        );














In my code
  1. var cookie = $.cookie(cookieName);
This line cause a error. Can any one please ?



'numbering' - widgets is only using my purpose. And this is not an issue although i add this for making the code more visible for someone.
