How to filter the object what we want from json data..?

Question

I am getting the response from backend, it return the json data.

But I need to pass the object separately to "handlebars.js" - templates.

In this case, how do I iterate the json response and filter the data what I want?

My sample data :

{
    "username":"xxxx",
    "name":"yyyyy",
    "allLocales":[
        {           "name":"Afrikaans"
        },
        {           "name":"Albanian"
        }           "name":"Arabic"

    ],
    "userLocales":[
        {           "name":"English (US)"
        },
        {           "name":"Swedish"
        }

],
    "message":"New massage will be here"
}

How can I get the var username = {"username":"xxxx"}, and

var nantions = "allLocales":[
            {           "name":"Afrikaans"
            },
            {           "name":"Albanian"
            }           "name":"Arabic"

        ]

and like so..?

Answer 1

You can use a method to easy parse your data.

with hasOwnProperty

Answer 2

Just reference the respective part of the object created by the JSON.

var nantions = jsonObj[ 'allLocales' ];

If you need to parse the JSON beforehand, use JSON.parse():

var jsonObj = JSON.parse( json );

EDIT

If you need the username really as an object, I think you are left with this:

var username = { 'username': jsonObj['username'] };

Answer 3

first please assign the sample data to a variable

var json_test = {
"username":"xxxx",
"name":"yyyyy",
"allLocales":[
    {           "name":"Afrikaans"
    },
    {           "name":"Albanian"
    },
    {   "name":"Arabic"
    }

],
"userLocales":[
    {           "name":"English (US)"
    },
    {           "name":"Swedish"
    }

], "message":"New massage will be here" };

after this if you want to access username the you should write like this

var username = json_test['username'];

var nantions = json_test['allLocales'];

Answer 4

You can access the properties of an object with a simple dot-notation:

objectName.propertyName

For example, in your case

var username = obj.username;   // xxxx
var nantions = obj.allLocales;   // array of Object
