1. $(document).ready(function () {
       $("#navigationToggle").click(function () {
           $(this).addClass("expand");
           var closed = $("#left_col_top").is(":hidden");
           if (closed)
            $("#left_col").removeClass();
            $("#left_col_top").show();
           else
            $("#left_col").addClass("noSidebar");
            $("#left_col_top").hide();
           setCookie("open", closed, 365);
       });
   
       var openToggle = getCookie("open");   
       if (openToggle=="true") {       
           $("#left_col").removeClass();
           $("#left_col_top").show();
       }
       else {       
            $("#left_col").addClass("noSidebar");
            $("#left_col_top").hide();
       }
   
   });
   
   function setCookie(c_name, value, exdays) {
       var exdate = new Date();
       exdate.setDate(exdate.getDate() + exdays);
       var c_value = escape(value) + ((exdays == null) ? "" : "; expires=" + exdate.toUTCString());
       document.cookie = c_name + "=" + c_value;
   }
   
   function getCookie(c_name) {
       var i, x, y, ARRcookies = document.cookie.split(";");
       for (i = 0; i < ARRcookies.length; i++) {
           x = ARRcookies[i].substr(0, ARRcookies[i].indexOf("="));
           y = ARRcookies[i].substr(ARRcookies[i].indexOf("=") + 1);
           x = x.replace(/^\s+|\s+$/g, "");
           if (x == c_name) {
               return unescape(y);
           }
       }
   }     
   
   
   
   
   
   
   
   
   
   
   
   
   
   
   
   
   
   
   
   
   
   
   
   
   
   
   
   
   
   
   
   
   
   
   
   
   
   
   
   
   
   
   

The ideas is that:

When i click #navigationToggle i want to it a class ( .expand ), to add a class to #left_col_top  and to #left_col

And when i click it back ( the same id #navigationToggle but now #navigationToggle.expand) to remove the classes that i just added.

1.   $("#navigationToggle").click(function () {  

            $(this).addClass('expand');
   

            $("#left_col").addClass('first-class');
            $("#left_col_top").addClass('second-class');
   

     });

     $("#navigationToggle.expand").click(function () { 
   

            $("#left_col").removeClass();
            $("#left_col_top").removeClass();
   

     });

But i don't know how to set the cookies because i want to save the effect
