Convert a JavaScript object to JSON

A colleague of mine was recently searching for a plug-in or script that can convert a JavaScript array to JSON. I asked him to check out JSON.stringify() in the json2.js library, which serializes the JavaScript object into JSON text. Here’s a sample if you do not know about this library:

Note: Make sure that you minify this library and then use the .js directly from your application. For demo purposes I am referring to this .js file directly. In production applications, it is not advisable to do so.

<script type="text/javascript" src="http://www.json.org/json2.js">
</script>
<script type="text/javascript">
        var arrCars = new Array("Toyota", "Mercedes", "BMW");           
        var jsonStr = JSON.stringify(arrCars);
        alert(jsonStr);
</script>
JavaScript to JSON

    As a note, JSON.parse is native in modern browsers & json2.js is helpful for older browsers.

    Curry is a spice mixture of widely varying compositions. My site is called devcurry since it is a mixture of ideas, experiments and thoughts for developers to cook ;)

    Hi,
    The link to get the json2.js file seems not work, the page: json.org/json2.js returns 404 error. But it can be downloaded from:
    https://github.com/douglascrockford/JSON-js/blob/master/json2.js
    In modern browsers, the JSON.stringify() works without json2.js .
