You can read JSON arrays the same way read normal objects in JavaScript via dot notation. This will work on only JSON Objects.
var json = {"STOCKQTY":20,"PHYSICALQTY":10};
console.log(json.PHYSICALQTY);If you Have saved this json under another object You need to go deeper, eg.
var response = {AlreadySaved: [{"STOCKQTY":20,"PHYSICALQTY":10}] };
console.log(response.AlreadySaved[0].PHYSICALQTY);have json (eg from the response) as string not object.
console.log(typeof(someJson)); //stringIn that case, You need to parse this string into json using the JSON parse method.
var json = JSON.parse(someJsonAsString);Source: stackoverflow.com
