How do I get the key of object inside object?

Question

I have an object and a for in loop that looks like this:

var golom = {
    MRTU03: {
        Temp: "10",
        Sp: "11"
    },
    MRTU09: {
        Temp: "8",
        Sp: "7"
    }
};
for (var f in golom) {
    $('body').append('hi ' + golom[f]);
}

As it is it's printing:

hi [object Object]hi [object Object]

to the body, but how can I get it to print

hi MRTU03hi MRTU09

??

Thanks!

Replace `golom[f]` with `f`. `f` is the key. – Felix Kling May 16 '13 at 15:59 — Felix Kling, May 16 '13 at 15:59

for (var f in golom) {
    $('body').append('hi ' + f);
    $('body').append('hi ' + golem[f].Temp); // Temp
    $('body').append('hi ' + golem[f].Sp); // Sp
}

Could be: for (var f in golom) { $('body').append('hi ' + f,'hi ' + f.Temp,'hi ' + f.Sp); } – A. Wolff May 16 '13 at 16:05

would it be `f.Temp` and `f.Sp`? or `golom[f].Temp` and `golom[f].Sp`? – wirey00 May 16 '13 at 16:06

@wirey It is actually, golom[f].Temp, but I have no idea why, f.Temp is undefined! – dezman May 16 '13 at 16:20
Can you fix this answer? f.Temp will always be undefined. – dezman May 16 '13 at 16:27
Answer fixed, strange! – Chris Dixon May 17 '13 at 06:56

Try this

var golom = {
    MRTU03: {
        Temp: "10",
        Sp: "11"
    },
    MRTU09: {
        Temp: "8",
        Sp: "7"
    }
};
for (var f in golom) {
    $('body').append('hi ' + f);
}
