How do I replace the "Argentina" key with a javascript variable string?
jQuery(document).ready(function() {
    $.getJSON('countries.json', function(data) {
        var output= data.Argentina[0].countryPhone1;
        alert(output);
     });
});
Here's what my .json data file looks like:
{
    "Argentina": [{
        "countryName":"Argentina",
        "countryPhone1":"1234"
    }],
    "Brazil": [{
        "countryName":"Brazil",
        "countryPhone1":"5678"
    }]
}
I tried applying the suggested solutions here, here and here, but I couldn't figure out a way to adapt them to my example.
