How to add new json node in javascript

Question

Here is my current json response.

[{"id":1,"name":"Yangon","$$hashKey":"object:170"}]

But I want to add new node to above json as follow,

[{"id":1,"name":"Yangon","$$hashKey":"object:170", "township_id": 1, "township_name": "Ahlone"}]

Please help me how to do it. Thanks in advance.

@naomik - It's not? (If you assume it's a string, it is valid JSON. Though it doesn't really make sense to add properties to JSON: I'd parse it and manipulate the resulting object...) — nnnnnn

This has syntax errors. How and where did you test it ?

angular.extend is another way of doing this.

var arr = [{ "id": 1, "name": "Yangon", "$$hashKey": "object:170" }];
arr[0] = angular.extend(arr[0], {
    "township_id": 1,
    "township_name": "Ahlone"
});

Don't forget the original data exists in an array

@naomik Sorry about that. Corrected.

You need to store your response into a variable (it probably already is) and just add whatever key/values you want:

Example

var arr = [{ "id": 1, "name": "Yangon", "$$hashKey": "object:170" }];

arr[0]['township_id'] = 1;
arr[0]['township_name'] = 'Ahlone';

Result

[{"id":1,"name":"Yangon","$$hashKey":"object:170","township_id":1,"township_name":"Ahlone"}]
