json stringifying array problem

using json.js from http://www.json.org/json.js

for array with the string keys

var test = new Array;

test["i1"]="v1";

test["i2"]="v2";

test["i3"]="v3";

var test_text = JSON.parse(stringify);

//test_text: []

if dim test as object, the json act as your expected.

var test = new Object;
