how to parse below simple json response?

BackGround : I am trying to parse this simple json response in my SenchaTouch Application.

json response:

{
    "Australia": 
    [
        {
            "Currency": "AustralianDollar",
        }
    ],
    "INDIA": 
    [
        {
            "Currency": "INR"
        }
    ],
    "USA": 
    [
        {
            "Currency": "USD"
        }
    ]
}

I want to fetch country's currency based on the Country name.

I am trying to fetch the currency value as below.

var country = text.Australia.name;
console.log('Country name is'+country);

but it gives me error. Can any one please explain on how to parse give country name as input and fetch the currency?

Thank you, Gendaful

Best way to do this if by using JSON.parse(). All browsers does not support this but you can get fallback by using Douglas Crockford implementations at https://github.com/douglascrockford/JSON-js

In Sencha Touch you should use

var object = Ext.decode(text);

to convert a json string into an Object. Then, in your case, since "Australia" in not an object but an array, you need to get the first element currency by

object.Australia[0].Currency;

You can use jQuery's $.parseJSON()

After that you can use:


    var text = $.parseJSON(jsonString);
    var currency = text.Australia[0].Currency;

Being the jsonString, the one you obtain via JSON.

Hope this helps!

The simplest way to do it is:

var obj = eval("(" + text+ ')');

Check out json.org for better/safer ways to do it.

Working example here.

Check out this compatibility chart for using JSON.parse(text);.

If text is the JSON string you can do this:

var obj = JSON.parse(text);
var australia = obj.Australia;
var aussie_currency = australia[0].Currency;

Note that the odd nesting of the object containing Currency inside of an array causes the need for the array index reference [0].
