'JSON' is undefined error in JavaScript in Internet Explorer

javascript jquery json internet-explorer

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/

javascript jquery json internet-explorer

<!DOCTYPE html>

Otherwise IE8 is not acting right. Also you should use:

<meta http-equiv="X-UA-Compatible" content="IE=EDGE" />

javascript jquery json internet-explorer

Please add json2.js in your project . i was faced the same issue i have fixed.

please use the link: https://raw.github.com/douglascrockford/JSON-js/master/json2.jsand create new file json.js, copy the page and past into newly created file , and move that file into your web application.

I hope it will work.
