如何在JavaScript cookie中存储数组？

Question

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!

Answer 1

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(',')

Answer 2

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]
