jQuery JSON to string?

Question

Instead of going JSON a json string and using $.parseJSON, I need to take my object and store it in a variable as string representing JSON.

(A library I'm dealing with expects a malformed JSON type so I need to mess around with it to get it to work.)

What's the best way to do this?

Answer 1

Edit: You should use the json2.js library from Douglas Crockford instead of implementing the code below. It provides some extra features and better/older browser support.

Grab the json2.js file from: https://github.com/douglascrockford/JSON-js

// implement JSON.stringify serialization JSON.stringify = JSON.stringify || function (obj) {     var t = typeof (obj);     if (t != "object" || obj === null) {         // simple data type         if (t == "string") obj = '"'+obj+'"';         return String(obj);     }     else {         // recurse array or object         var n, v, json = [], arr = (obj && obj.constructor == Array);         for (n in obj) {             v = obj[n]; t = typeof(v);             if (t == "string") v = '"'+v+'"';             else if (t == "object" && v !== null) v = JSON.stringify(v);             json.push((arr ? "" : '"' + n + '":') + String(v));         }         return (arr ? "[" : "{") + String(json) + (arr ? "]" : "}");     } };  var tmp = {one: 1, two: "2"}; JSON.stringify(tmp); // '{"one":1,"two":"2"}'

I use

$.param(jsonObj) 

which gets me the string.
