javascript - Firebase use query result outside function

OK, I'm quite new to Javascript and I'm trying to use firebase as the back end for a simple game I'm making.

I have the following very simple javascript code accessing my data:

    var myData = new Firebase("https://theurl.firebaseio.com/Player/results");
    var p1;
    var player1 = myData.child("1");
    player1.on("value", function(snapshot) {
        p1 = snapshot.val();  
        console.log(p1["Name"]+ " " + p1["Draws"]);
    });
    /*
    This line seems to be the problem, how do I assign the result of the query outside the above function? */
    p1["Draws"] += 1;
    player1.update({
        "Draws": p1["Draws"]
    });


The variable p1 doesn't get assigned properly. How can I get around this?
