Question

Answer 1

Still not exactly sure what you need but i hope this will help. This is a sample that will allow you to access the items on any page, its just a sample! It uses the cookieName to identify it across the pages.

//This is not production quality, its just demo code. var cookieList = function(cookieName) { //When the cookie is saved the items will be a comma seperated string //So we will split the cookie by comma to get the original array var cookie = $.cookie(cookieName); //Load the items or a new array if null. var items = cookie ? cookie.split(/,/) : new Array();  //Return a object that we can use to access the array. //while hiding direct access to the declared items array //this is called closures see http://www.jibbering.com/faq/faq_notes/closures.html return {     "add": function(val) {         //Add to the items.         items.push(val);         //Save the items to a cookie.         //EDIT: Modified from linked answer by Nick see          //      http://stackoverflow.com/questions/3387251/how-to-store-array-in-jquery-cookie         $.cookie(cookieName, items.join(','));     },     "remove": function (val) {          //EDIT: Thx to Assef and luke for remove.         indx = items.indexOf(val);          if(indx!=-1) items.splice(indx, 1);          $.cookie(cookieName, items.join(','));        },     "clear": function() {         items = null;         //clear the cookie.         $.cookie(cookieName, null);     },     "items": function() {         //Get all the items.         return items;     }   } }   

So on any page you can get the items like this.

var list = new cookieList("MyItems"); // all items in the array. 

Adding items to the cookieList

list.add("foo");  //Note this value cannot have a comma "," as this will spilt into //two seperate values when you declare the cookieList. 

Getting all the items as an array

alert(list.items()); 

Clearing the items

list.clear(); 

You can add additional things like push and pop quite easily. Again hope this helps.
