JSON undefined

Here are some scripts that you can implement in your own javascript tag, class to implement json serialisation and parsing

var JSON = JSON || {};
// 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 ? "]" : "}");
}
};
// implement JSON.parse de-serialization
JSON.parse = JSON.parse || function() {
var r = "(?:-?\\b(?:0|[1-9][0-9]*)(?:\\.[0-9]+)?(?:[eE][+-]?[0-9]+)?\\b)", k = '(?:[^\-\\x08\\x0a-\\x1f"\\\\]|\\\\(?:["/\\\\bfnrt]|u[0-9A-Fa-f]{4}))';
k = '(?:"' + k + '*")';
var s = new RegExp(
"(?:false|true|null|[\\{\\}\\[\\]]|" + r + "|" + k + ")", "g"), t = new RegExp(
"\\\\(?:([^u])|u(.{4}))", "g"), u = {
'"' : '"',
"/" : "/",
"\\" : "\\",
b : "\u0008",
f : "\u000c",
n : "\n",
r : "\r",
t : "\t"
};
function v(h, j, e) {
return j ? u[j] : String.fromCharCode(parseInt(e, 16));
}
var w = new String(""), x = Object.hasOwnProperty;
return function(h, j) {
h = h.match(s);
var e, c = h[0], l = false;
if ("{" === c)
e = {};
else if ("[" === c)
e = [];
else {
e = [];
l = true;
}
for ( var b, d = [ e ], m = 1 - l, y = h.length; m = 0;)
delete f[i[g]];
}
return j.call(n, o, f);
};
e = p({
"" : e
}, "");
}
return e;
};
}();
