How do I change a JSON object into an array key/value pairs through code?
from:
{
'name':'JC',
'age':22
}
to:
['name':JC,'age':22] //actually, see UPDATE
UPDATE:
...I meant:
[{"name":"JC"},{"age":22}]

May be you only want understand how to iterate it:
var obj = { 'name':'JC', 'age':22 };
for (var key in obj)
{
alert(key + ' ' + obj[key]);
}
Update:
So you create an array as commented:
var obj = { 'name':'JC', 'age':22 };
var obj2 = [];
for (var key in obj)
{
var element = {};
element[key] = obj[key]; // Add name-key pair to object
obj2.push(element); // Store element in the new list
}

well I want to put it into one BIG array containing many objects.. like [{..},{..}] with one Object per property..
If you're trying to convert a JSON string into an object, you can use the built in JSON parser (although not in old browsers like IE7):
JSON.parse("{\"name\":\"JC\", \"age\":22}");
Note that you have to use double quotes for your JSON to be valid.

There is no associative array in JavaScript. Object literals are used instead. Your JSON object is such literal already.
["name","JC","age",22]or[{"name":"JC"},{"age":22}]?
