Serializing to JSON in jQuery [duplicate]

JSON-js – JSON in JavaScript.

To convert an object to a string, use JSON.stringify:

var json_text = JSON.stringify(your_object, null, 2);

To convert a JSON string to object, use JSON.parse:

var your_object = JSON.parse(json_text);

It was recently recommended by John Resig:

…PLEASE start migrating
your JSON-using applications over to
Crockford’s json2.js. It is fully
compatible with the ECMAScript 5
specification and gracefully degrades
if a native (faster!) implementation

In fact, I just landed a change in jQuery yesterday that utilizes the
JSON.parse method if it exists, now
that it has been completely specified.

I tend to trust what he says on JavaScript matters 🙂

All modern browsers (and many older ones which aren’t ancient) support the JSON object natively. The current version of Crockford’s JSON library will only define JSON.stringify and JSON.parse if they’re not already defined, leaving any browser native implementation intact.
