parsing dynamic JSON Response

Question

{
    'AddUpdateResult': {
        "Patient": "24919"
    }
}

Here is a part of my response, The problem i am facing is the JSON response i am getting is dynamic and i need to parse it. In another scenario, i get something like this.

   {
        'EditUpdateResult': {
            "Patient": "24919"
        }
    }

When i try something like this, i get "Cannot read property Patient from null" and the reason is its expecting "EditUpdateResult".

json.AddUpdateResult.Patient

How can i access the key's dynamically. Like... json.whatever.Patient, so that it may AddUpdateResult or EditUpdateResult

Are you only dealing with two possible responses, or do you need a more general solution that can deal with any response that has a "patient" property? — Andrew N Carr

That isn't JSON. Strings can't be quoted using ' characters. — Quentin

JSON properties are quoted with double quotes, not single. Where is the JSON in your code? Is it a string? did you parse it into a JS object? Questions without code are hard to answer. — Ruan Mendes

It is possible to iterate over a JSON object without knowing the attribute names.

for (var key in p) {
    if (p.hasOwnProperty(key)) {
        alert(key + " -> " + p[key]);
    }
}

Using hasOwnProperty is useful if your object may have been prototyped. That probably isn't the case in this example (based on the supplied data), but good point nonetheless.

Do all of the responses only have one 'result'? If so try looping over it like this:

var patient;

for (var i in json) {
    patient = json[i].Patient;
}
