Does anyone have a piece of JavaScript code that creates a cookie and stores an array in it? If you also have the code to read through through cookie and delete it, that would be great as well. Thanks!

have a look at:
http://plugins.jquery.com/project/cookie https://plugins.jquery.com/cookie/
to store an array
$.cookie('COOKIE_NAME', escape(myarray.join(',')), {expires:1234});
to get it back
cookie=unescape($.cookie('COOKIE_NAME'))
myarray=cookie.split(',')

If your data can contain special characters, you should use JSON encode/decode. Otherwise, an entry containing "," will give incorrect decode result.

Okay, thanks. I tried the jquery example above and couldn't get it to work properly. I may just be missing something. You can create cookies while not using a web server correct?
Josh
Dang. Yes, you need to have a web server for this... Was hoping not to. Thanks.

there is no way to create cookies without a webserver josh, if you want to test locally you need to setup a home package like xampp

what if you array contains value with ',' within ? then your function is no use.
jQuery, Cookie plugin:
Converting an array into a string:
> JSON.stringify([1, 2]);
> '[1, 2]'
Then:
$.cookie('cookie', '[1, 2]');
And then parse it:
JSON.parse($.cookie('cookie'));
> [1, 2]
