Iterate over a JSONObject

Question

JSON library called JSONObject is used(I don't mind switching if I need to)

We know how to iterate over JSONArrays, but when we parse JSON data from Facebook we don't get an array, only a JSONObject, but I need to be able to access an item via its index, such as JSONObject[0] to get the first one, How can we do it?

{
   "http://http://url.com/": {
      "id": "http://http://url.com//"
   },
   "http://url2.co/": {
      "id": "http://url2.com//",
      "shares": 15
   }
   ,
   "http://url3.com/": {
      "id": "http://url3.com//",
      "shares": 15
   }
}

Answer 1

There is no more simple and secure solution than using an iterator.

JSONObject names () method returns a JSONArray of the JSONObject keys, so you can simply walk though it in loop:

JSONObject objects = new JSONObject ();
JSONArray key = objects.names ();
for (int i = 0; i < key.length (); ++i) {
   String keys = key.getString (i); 
   String value = objects.getString (keys);
}

Answer 2

to iterate over a json file you can use the following code:

jObj = new JSONObject(contents.trim());
Iterator<String> keys = jObj.keys();
while(keys.hasNext()) {
    String key = keys.next();
    if (jObject.get(key) instanceof JSONObject) {
    }
}

Answer 3

for(int i = 0; i<jobject.names().length(); i++){
    Log.v(TAG, "key = " + jobject.names().getString(i) + " value = " + jobject.get(jobject.names().getString(i)));
}

I used this to iterate over names

Answer 4

Iterator<JSONObject> itr = jsonObject.values().itr();
while (itr.hasNext()) {
 jsonChildObject = itr.next();
 // Do whatever you want with ChildObject 
  String id = (String) jsonChildObject.get("id");
}

Answer 5

JSONObject obj = new JSONObject ();
JSONArray key = object.names ();

for (int i = 0; i < key.length (); ++i) {

   String key = key.getString (i); // Here's your key
   String value = obj.getString (key); // Here's your value

}

Answer 6

Simple method of iterating over the json file is 

for(String key : jsonObject.keySet())

Answer 7

JSONObject names () method returns a JSONArray of the JSONObject keys, so you can iterate it in loop:

JSONObject createobject = new JSONObject ();
JSONArray getkeys = object.names ();
for (int i = 0; i < getkeys.length (); ++i) {
   String key = getkeys.getString (i); // Here's your key
   String value = createobject.getString (key); // Here's your value
}

Answer 8

jsonOb = new JSONObject();
Iterator<String> keys = jsonOb.keys();
while(keys.hasNext()) {
    String key = keys.next();
    if (jObject.get(key) instanceof JSONObject) {
    }
}

Answer 9

Use for loop

for (var key in obj) {
  if (obj.hasOwnProperty(key)) {
    console.log(key + ": " + obj[key]);
  }
}

Answer 10

You can use the following method to itterate over json file

json_object = json.loads(json_file)
for element in json_object: 
    for value in json_object['Name_OF_YOUR_KEY/ELEMENT']:
        print(json_object['Name_OF_YOUR_KEY/ELEMENT']['INDEX_OF_VALUE']['VALUE'])

Iterate through JSONObject in java (android)

1. String jsonstring = "{ "child": { "something": "value", "something2": "value" } }";
2. JSONObject resobj = new JSONObject(jsonstring);
3. Iterator<?> keys = resobj. ...
4. while(keys. hasNext() ) {
5. String key = (String)keys. next();
6. if ( resobj. get(key) instanceof JSONObject ) {
7. JSONObject xx = new JSONObject(resobj. ...
8. Log.

To iterate through JSONArray?

Here you go

getJSONObject("JObjects"); JSONArray getArray = getObject. getJSONArray("JArray1"); for(int i = 0; i < getArray. size(); i++) { JSONObject objects = getArray. getJSONArray(i); //Iterate through the elements of the array i. //Get thier value. //Get the value for the first element and the value for the last element. }

Assuming your JSON object is saved in a file "simple.json", you can iterate over the attribute-value pairs as follows:

JSONParser parser = new JSONParser();

Object obj = parser.parse(new FileReader("simple.json"));

JSONObject jsonObject = (JSONObject) obj;

for(Iterator iterator = jsonObject.keySet().iterator(); iterator.hasNext();) {
    String key = (String) iterator.next();
    System.out.println(jsonObject.get(key));
}
