  • A little clarification, given that you wonder if it's possible. Cookies are simple plain text dictionary entries composed 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 Nov 17 '11 at 08:27

You combine 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]

  • Thanks alot for your reply!!! That was really helpful. I'm having another issue looping through the string result "var storedAry = JSON.parse($.cookie('name'));". Can you help me out with a snippet? – Blingue Nov 17 '11 at 12:29

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.
