JSON.stringify and JSON.parse not working in IE9?

I'm using JSON.Stringify and JSON.parse everywhere and it works fine with Firefox. It's working no more with IE9 nor does it work in IE8. What can I do?

the mere issue is, that sending UTF-8 headers will invalidate the JSON (IE doesn't/didn't like that). as the issue is described, that might still apply for IE9... once wrote a how to, a few years ago. adding JSON support to a browser which can parse native JSON is probably not the optimal solution, since it produces useless overhead - only because failing to deliver the JSON in the expected format.

For an alternative, in a scenario where you might need to run in strict mode for whatever reason (I have another library that includes "use strict"), you can look here: https://github.com/douglascrockford/JSON-js. I modified this to check first if JSON is undefined, and only generate the function JSON.parse if it is: 

if (typeof JSON === "undefined") {
    var JSON = {
        parse: <insert value of json_parse from library here>
    };
}

My issue was application code not working in IE9 (strict mode being used by a participating library, I believe). That solved the problem for me.

why do you want to depend on the browser having the object instead just include the script file by Douglas Crockford.. You can find the minifed file here: http://www.json.org/js.html

Once imported you dont have to worry abt the method existing in a browser.

JSON.stringify starts with a lower-case s. Both stringify and parse are available in IE8+, but only in standards mode.

Prepend your document with <!DOCTYPE html> if you're currently using quirks mode. Also, watch the capitalization of the JavaScript methods you call - all built-in ones start with a lower-case character.
