Serialize javascript object to json and back

I am using to a jQuery post method to send some data to a server. Rather than constructing the JSON string myself, I would like to simply use a JavaScript object. When I get the return string (in JSON) I would like to automatically construct a corresponding JavaScript object.

Is this possible?

If you use jQuery.getJSON you don't have to care about stringifying and parsing json, jquery does it for you.

Checkout JSON.stringify() and JSON.parse() in JSON2 documentation

Example:

myData = JSON.parse(text); // from json string to js object

var myJSONText = JSON.stringify(myObject, replacer); // js object to json string

you should use Douglas Crockford's JSON2 library.

That way, you could:

var jsonString = JSON.stringify(obj);

or

var Obj = JSON.parse(jsonString);

Yes.

If the JSON object is available, you can use :

var aString = JSON.stringify(anObject);

to transform an object into JSON string.

You can also convert a string into an object with

var obj = JSON.parse(aString)

To be sure that JSON is available, you can include this file https://github.com/douglascrockford/JSON-js
