I would like to get the value of "name" from the example json object below without knowing the name of the object (123) because this could be anything and I dont know before.

{
  "123": {
    "email": "kato@firebase.com",
    "name": "Kato"
  }
}

Open in new window


I know it dont work like this but I look for something like
console.log(object[0].name);

to make it more clear.

Is there always only one child object in the JSON object? If so, you could use
object = {
  "123": {
    "email": "kato@firebase.com",
    "name": "Kato"
  }
};
for (var i in object) {
  console.log(object[i].name);
}

To get the first (or Nth if you desire) object from an object you can use Object.keys()

In your case for the first object use index 0
var data = {
  "123": {
    "email": "kato@firebase.com",
    "name": "Kato"
  }
};
console.log(data[Object.keys(data)[0]].name);

Thank you guys, this was exactly what I needed.
Both solutions work fine for me but the second solution is best for me since I have some cases with more than   1 result.
