jquery save json data object in cookie

You can serialize the data as JSON, like this:

$.cookie("basket-data", JSON.stringify($("#ArticlesHolder").data()));

Then to get it from the cookie:

$("#ArticlesHolder").data(JSON.parse($.cookie("basket-data")));

This relies on JSON.stringify() and JSON.parse() to serialize/deserialize your data object, for older browsers (IE<8) include json2.js to get the JSON functionality. This example uses the jQuery cookie plugin

It is not good practice to save the value that is returned from JSON.stringify(userData) to a cookie; it can lead to a bug in some browsers.

Before using it, you should convert it to base64 (using btoa), and when reading it, convert from base64 (using atob).

val = JSON.stringify(userData)
val = btoa(val)

write_cookie(val)

Now there is already no need to use JSON.stringify explicitly. Just execute this line of code

$.cookie.json = true;

After that you can save any object in cookie, which will be automatically converted to JSON and back from JSON when reading cookie.

var user = { name: "name", age: 25 }
$.cookie('user', user);
...

var currentUser = $.cookie('user');
alert('User name is ' + currentUser.name);

But JSON library does not come with jquery.cookie, so you have to download it by yourself and include into html page before jquery.cookie.js

use JSON.stringify(userData) to coverty json object to string.

var dataStore = $.cookie("basket-data", JSON.stringify($("#ArticlesHolder").data()));

and for getting back from cookie use JSON.parse()

var data=JSON.parse($.cookie("basket-data"))
