Parsing JSON with JavaScript

I understand to get the value of a json data, for instance var json = [{"country":"US"}], I can do it like json[0].country.

I've this json data [{"0":"US"}], so how do I retrieve the data then?

As a side note, properties in general an be accessed with array notation. Even with an object `var myvar = { mykey: myvalue }` you can do `myvar[mykey]`. You can event execute functions `var myvar = { mykey: function(){...} }` with `myvar[mykey]()`. — Didier Ghys, Dec 21 '11 at 09:34

You could use json[0]['0'] as the "0" is just a name as far as JavaScript is concerned

Note that `json[0][0]` (notice lack of quotes) will also work. The bracket notation converts everything in the brackets to a string, so `0` will be turned to `'0'`. – Zirak Dec 21 '11 at 13:38

json[0]["0"]

Not really much more to add to that.

In this case you'll retrieve with

 json[0]["0"]

you may acess the value with:

var json = [{"0":"US"}]
json[0]["0"]

Here the key of the only object into the array is string so you can access it with:

var bar = [{"0":"US"}];
console.log(bar[0]['0']); // 'US'

If I'm understanding your question correctly, it would just be

json[0]["0"]

to retrieve your data. The zero is in quotes the second time round, because it's stored as a string in your example.
