Convert JSON array into individual JS variables

Question

I have a JSON array:

{"a":"apple,"b":"banana","c":"carrot"}

I want to split each part of the array into seperate variables, ie,

a = "apple",
b = "banana";
c = "carrot";

I have googled my goggles off but can't seem to find a correct way to do this. I am new to JSON and have done a fair bit of reading but what I am after doesn't seem to be referenced within my grasp.

EDIT: There seems to be confusion as to whether my array is a string or object. I am receiving a response from PHP as follows:

$json = array(
    'a' =>  $a,
    'b'     =>  $b,
    'c' =>  $c,
    );
    echo json_encode($json);

My JS code is as follows:

var data = ajax.responseText;
data = JSON.parse(data);

I get {"a":"apple,"b":"banana","c":"carrot"} as a result of

json.stringify(data);

One example of how you can do this is found here.

It assumes you want to put the variables into global scope. If this is the case, this will work:

function extract(variable) {
    for (var key in variable) {
        window[key] = variable[key];
    }
}

var obj = {"a":"apple","b":"banana","c":"carrot"}

extract(obj);

alert(a);
alert(b);
alert(c);
