Accessing nested json objects is just like accessing nested arrays. Nested objects are the objects that are inside an another object.
In the following example 'vehicles' is a object which is inside a main object called 'person'. Using dot notation the nested objects' property(car) is accessed.
Example-1
<html> <body> <script> var person = { "name":"Ram", "age":27, "vehicles": { "car":"limousine", "bike":"ktm-duke", "plane":"lufthansa" } } document.write("Mr Ram has a car called" + " " + person.vehicles.car); </script> </body> </html>
Output
Mr Ram has a car called limousine
Example-2
In the following example, an object called "air-lines" is doubly nested (nested inside a nested object). The property of that doubly nested object(lufthansa) is accessed through dot notation as shown below.
<html> <body> <script> var person = { "name":"Ram", "age":27, "vehicles": { "car":"limousine", "bike":"ktm-duke", "airlines":{ "lufthansa" : "Air123", "British airways" : "Brt707" } } } document.write("Mr Ram travels by plane called" + " " + person.vehicles.airlines.lufthanza); </script> </body> </html>
Output
Mr Ram travels by plane called Air123
