A little clarification, given that you wonder if it's possible. Cookies are simple plain text dictionary entries posed of key and value:
foo=bar. You can't even have real numbers in cookies. However, you can emulate any data type if you are able to represent it as text. – Álvaro González Commented Nov 17, 2011 at 8:27

Reset to default 13You bine the use jQuery.cookie plugin and JSON and solve your problem.
When you want to store an array,You created an array in JS and use JSON.stringify to transform it into an string and stored with $.cookie('name', 'array_string')
var myAry = [1, 2, 3];
$.cookie('name', JSON.stringify(myAry));
When you want to retrive the array inside the cookie, you use $.cookie('name') to retrive the cookie value and use JSON.parse to retrive the array from the string.
var storedAry = JSON.parse($.cookie('name'));
//storedAry -> [1, 2, 3]
You could store the array as a JSON array in your cookie. From the cookie point of view, its a regular text string but you can parse the content to re-build the array.
