Convert Javascript Array to JSON

Question

Hay I have an Array (var cars = []) which hold a few integers. I've added a few values to the array, but i now need to send this array to a page via jQuery's .get method. But i want to send it as a JSON object.

How do i convert an array to a JSON object?

Answer 1

Take this script: http://www.json.org/json2.js

And call:

var myJsonString = JSON.stringify(yourArray);

Answer 2

From version 1.4.1 of JQuery you could also use JQuery.parseJSON directly.

var obj = jQuery.parseJSON('{"name":"John"}');
alert( obj.name === "John" );

Answer 3

There's a jQuery plugin for that here:
