JSON loop through single object

Question

How can i get the second values (dates) in a javascript array?

I am new to this and i can't get it to work.

{"0":"11-28-2012","4":"11-29-2012","10":"12-03-2012"}

Thanks!

You should be able to do this by simply doing `json_object[1]`. — Jeremy, Dec 04 '12 at 02:15

What do you mean by "second dates"? The object you have does have no ordered values, and no key "1". — Bergi, Dec 04 '12 at 02:21

A very simple loop is below. You should check that the object hasOwnProperty which is important for more complicated objects.

If your object is called obj:

obj = {"0":"11-28-2012","4":"11-29-2012","10":"12-03-2012"}; 
for (var i in obj) {
    console.log(obj[i]);
}

Or without the loop:

obj = {"0":"11-28-2012","4":"11-29-2012","10":"12-03-2012"};
console.log(obj[0]); // displays "11-28-2012"

You should not name the object "`arr`", as it is no array. – Bergi Dec 04 '12 at 02:20
You are completely correct, I have updated the answer. Thanks. – timc Dec 04 '12 at 02:21
Hi, thanks for your answers, but i cant get it to work. I have a PHP that does json_encode on array, and then when i console.log() the returned array via ajax i get that object returned, but i cant loop through it..http://jsfiddle.net/qL6dk/ – intelis Dec 04 '12 at 02:25
Unfortunately I can't get your fiddle to work for me. What happens when you try to loop through it? – timc Dec 04 '12 at 02:34
it looks like its returning parts of string..it does not recognize it as object.. – intelis Dec 04 '12 at 02:43
i got it to work..for (i in ret) { console.log(ret[i].attributes.datum); } – intelis Dec 04 '12 at 02:48
Nice one, there must be more to the object than specified. – timc Dec 04 '12 at 02:55

In javascript, the order of keys is nondeterministic. if you really want, you can use underscore values function

_.values(obj)[1]

Not really sure want do you want. But if you want to get date in month-date-year use split().

var jsonDate = {"0":"11-28-2012","4":"11-29-2012","10":"12-03-2012"};

console.log(jsonDate["0"].split('-')[1]); //28
console.log(jsonDate["4"].split('-')[1]); //29
console.log(jsonDate["10"].split('-')[1]); //03
