jQuery.parseJSON('{"name":"John"}') converts string representation to object
but I want the reverse. Object is to be converted to JSON string
I got a link http://www.devcurry.com/2010/03/convert-javascript-object-to-json.html
but it need to have json2.js. Does jQuery have a native method to do this?

jQuery does only make some regexp checking before calling the native browser method window.JSON.parse(). If that is not available, it uses eval() or more exactly new Function() to create a Javascript object.
The opposite of JSON.parse() is JSON.stringify() which serializes a Javascript object into a string. jQuery does not have functionality of its own for that, you have to use the browser built-in version or json2.js from http://www.json.org
JSON.stringify() is available in all major browsers, but to be compatible with older browsers you still need that fallback.

this may be helpful:
var theObject = (typeof data == "string") ? jQuery.parseJSON(data) : data;

@tekretic: I hope you're trolling. Chrome implements the
JSON host object since day 1.

@jAndy: Oh wow, sorry. Not trolling but OH so wrong. Turns out native JSON support was added to WebKit in mid 2009, making it supported since Chrome 3.0. My previous, totaly inaccurate comment was based on a half of this outdated question combined with the CMS I'm working on at the moment which actually replaces window.JSON with its own library, meaning
JSON.stringify() isn't defined. Quite a fail on all counts.Molomby
For those interested, here's a nice chart of native JSON support in different browsers.

@jAndy: dont confuse me; : JSON.stringify 'serialises' an object, please say that its just a mistake

Also useful is Object.toSource() for debugging purposes, where you want to show the object and its properties for debugging purposes. This is a generic Javascript (not jQuery) function, however it only works in "modern" browsers.

Convert JavaScript object to json data
$("form").submit(function(event){
event.preventDefault();
var formData = $("form").serializeArray(); // Create array of object
var jsonConvertedData = JSON.stringify(formData); // Convert to json
consol.log(jsonConvertedData);
});
You can validate json data using http://jsonlint.com

You can use the excellent jquery-Json plugin:
http://code.google.com/p/jquery-json/
Makes it easy to convert to and from Json objects.

Please recommend SPL methods over add-on logic libraries.
David J Eddy
SPL = Standard PHP Library. Guess in this case is would be SJL (standard javascript library).
George Filippakos
The question is about jQuery & Javascript. It nothing to do with PHP, PHP libraries or SPL.
David J Eddy
standard libraries are standard libraries; don't matter the language. My point being it is better to recommend a solution that teaches the language over 'use this plugin' syndrome.
David J Eddy
Exactly, why reinvent the wheel...use the standard abilities of a language over a 'plugin' but I digress.
