Convert Object to JSON string

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?

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

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.

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.

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.
