如何使用javascript从json数组中获取值?

I have a PHP file which only return an array with the drivers and a url:

{"drivers":[{"marco":[0],"luigi":[123],"Joan":[2444],"George":[25]}, {"marco":[23],"luigi":[3],"Joan":[244],"George":[234]}],"url":"google.es"}

Is the json correctly structured? And I'm trying to get the result using jQuery and AJAX by this way:

$.getJSON('calculate.php&someparams=123', function(data) {
    alert("url - " + data.url);
    var arr = data.drivers;

    for (var i = 0; i < arr.length; i++) {
        alert(arr[i] + " - " + arr[i][0]);
    }
});

I see the first alert() with the url, but the second one does not works... What am I doing wrong?

If you need more info let me know and I'll edit the post.

    The drivers is not an array, it is an object, you use $.each to iterate through the object elements.

    $.getJSON('calculate.php&someparams=123', function(data) {
        $.each(data.drivers, function(key, value){
            $.each(value, function(key, value){
                console.log(key, value);
            });
        })
    });
