JSON Object

JSON Objects

{ "name":"junlan", "age":30, "car":"vw" }


Accessing Object Values

myObj = { "name":"junlan", "age":30, "car":"vw" };

1. x = myObj.name;
2. x = myObj["name"];

Looping an Object
You can loop through object properties by using the for-in loop:

Example
myObj = { "name":"junlan", "age":30, "car":"vw" };
for (x in myObj) {
  var obj=myObj[x];
}


Nested JSON Objects
myObj = {
  "name":"junlan",
  "age":30,
  "cars": {
    "car1":"Ford",
    "car2":"BMW",
    "car3":"Fiat"
  }
 }
x = myObj.cars.car2;
// or:
x = myObj.cars["car2"];

Modify Values

myObj.cars.car2 = "Mercedes";
myObj.cars["car2"] = "Mercedes";
Delete Object Properties

delete myObj.cars.car2;
