Creating Function to Parse JSON Data using substring

Question

i'm working in AS2 & it's looks like javascript alot

JSON

{
   "name": "Tom",
   "age": 20,
   "state": "usa"
}

now i cant parse JSON data in AS2 & need workaround function using substring something like that below and i load json file using loadVars()

var _lv:LoadVars = new LoadVars()
_lv.onData = function(data)
{
    var ex:Object = eval("data");
 var JSONTOArray:Object = ex.toString().split(',');
 var getname=JSONtoArray[0].substring(JSONtoArray[0].lastIndexOf('"name": "')+9,JSONtoArray[0].lastIndexOf('"')); 
}
_lv.load("MyJSON_URL");

now need to build function like

getThis('name'); // return Tom
getThis('age'); // return 20
getThis('state'); // return usa

The best solution is to use existing parser, because

you will not have to write your own code
it probably has common syntax like JSON.parse and JSON.stringify

var abc={
   "name": "Tom",
   "age": 20,
   "state": "usa"
};
console.log(abc['name']);     //Tom
console.log(abc['age']);      //20
console.log(abc['state']);    //usa

To parse a json data using ActionScript 2, you can use the JSON.as class ( from JSON.org ), after putting it in the same directory as your .fla, you can use it like this :

import JSON;

var json = new JSON();

var loader:LoadVars = new LoadVars();
    loader.onData = function(data)
    {   
        trace(json.parse(data).name);   // gives : Tom
    }
    loader.load('file.json');

Hope that can help.
