'JSON' is undefined error in JavaScript in Internet Explorer

Question

We are using jQuery in our application. We have used a jQuery plugin to implement JavaScript session.

It is working properly in Firefox and most Internet Explorer 8

Answer 1

Maybe it is not what you are looking for, but I had a similar problem and i solved it including JSON 2 to my application:

Other browsers natively implements JSON but IE < 8 (also IE 8 compatibility mode) does not, that's why you need to include it.

Here is a related question: JSON on IE6 (IE7)

UPDATE

the JSON parser has been updated so you should use the new one: http://bestiejs.github.io/json3/
