get MongoDB ObjectId in JSON via Javascript

Question

This is my JSON from PHP:

{"data" :
    [
        {
            "_id" : {
                "$id" : "4f977259b1445dce24000000"
            },
            "headline" : "asdfasdf",
            "date" : {
                "sec" : 1333584000,
                "usec" : 0
            },
            "text":"asdfasdfas"
        }
    ]
}

In Javascript I want to use the values and it works fine with

obj = JSON.parse(request);
console.log(obj.data[i].headline);

But how do I get the ObjectId?

It does not work like this:

console.log(obj.data[i]._id.$id);

I can verify that the answers gillesc and reach4thelasers work (at least in Safari). You may also want to have a look at stackoverflow.com/questions/2940424/… . — T. Junghans

It seems to work as expected when I try it http://jsfiddle.net/2CSWr/

console.log(json.data[0]._id.$id);

does output the right value

This works for me:

console.log(obj.data[0]._id['$id']);
