Javascript navigating class in for loop

Question

I am trying to go to the location json.responseJSON.Sites.LHR and on next iteration json.responseJSON.Sites.NJE so on and so on. notification on the first instance is a string "LHR" and second "NJE". Is this possible?

    for(var notification in json.responseJSON.Sites){
            console.log(json.responseJSON.Sites.notification);
    }

This is my json

{
"Sites": {
    "LHR": 1,
    "NJE": 1,
    "AZS": 1,
    "SGP": 1,
    "OHS": 1,
    "AZP": 1
  }
}

`console.log(json.responseJSON.Sites[notification]);` – tymeJV Apr 15 '15 at 17:50 — tymeJV, Apr 15 '15 at 17:50

You may have to access it as property access notation (instead of object.property do object['property']) such as:

  responseJSON = {
"Sites": {
    "LHR": 1,
    "NJE": 1,
    "AZS": 1,
    "SGP": 1,
    "OHS": 1,
    "AZP": 1
  }
};

for(var notification in responseJSON.Sites){
    console.log(notification + " : " + responseJSON.Sites[notification]);
    }

There's no array here. Why would you describe it that way? `responseJSON.Sites[notification]` is just one way of accessing a property value. – jfriend00 Apr 15 '15 at 17:53
Thanks for the correct term. I will update the answer – Jorge Zuverza Apr 15 '15 at 17:56
The example of `obj.prop` vs. `obj[prop]` is good. Plz add that to your answer to explain. – jfriend00 Apr 15 '15 at 17:57

No, I want the value of json.responseJSON.Sites.(variable) as in json.responseJSON.Sites.LHR and json.responseJSON.Sites.NJE console.log(notification) gives me "LHR" console.log(json.responseJSON.Sites.LHR) gives me 1 – Zac Borders Apr 15 '15 at 17:52
