CookieJar: JSON Cookies
Category: JavaScript
, Library
Lalit Patel has created a JavaScript Library to use JSON to store data in cookies.
JSON Cookies is built on top of Prototype and gives you a simple API to put and get JSON values into cookies:
JAVASCRIPT:
-
-
var jar = new CookieJar({
-
expires:3600, // seconds
-
path: '/'
-
});
-
-
var dog = {name: 'Jacky', breed: 'Alsatian', age:5};
-
-
jar.put('mydog', dog);
-
mydog = jar.get('mydog');
-
-
alert("My dog's name is " + mydog.name);
-
alert("He is " + mydog.age + " years old");
-
alert("He is an " + mydog.breed);

Would be nice if you had posted the link… :)

A link to the download location might be handy.
Here it is:

The newest Prototype (1.5.1_rc2) includes json methods in it. This is because json.js extends the “Object object” prototype which is considered very bad and conflicts with some Prototype ajax methods.
@tonote
Yes I decided to use Prototype 1.5.1_rc2 but then since it is not a stable version, this script wont be of any immediate use to many. So I thought of using json.js and later when a toJSON() gets included in Prototype, I would change this script.
Thanks.
Lalit, tonote’s right, json.js will completely break Prototype’s Ajax requests. So you really should move to 1.5.1_rc2.
Also for those who do not wish to update to the RC version of Prototype just yet, you can use http://www.stevekallestad.com/blog/making_prototype_compatible_with_jsonjs.html (it allows for json.js to continue its bad behavior and not break Prototype’s ajax methods)
Why did you created this on the top of prototype? After seeing your code. I think it wouldn’t be too difficult to make it framework independent. But it is nice, I will do experiments with it, thanks (^-^)
Oh boy, answer is wrong… do I still get to enter?
I wrote a remake of this for Mootools:

dear lord- this breaks in IE! BEWARE!
even the author’s example breaks, sooooo watch out!
I wrote an article on using MooTools’ Hash.Cookie class, which is quite similar:
