looping through a JSON data structure

looping through a JSON data structure

I'm struggling to figure out how to properly iterate through this JSON object using only JavaScript. My goal is to store the token in one variable and the user details in separate variables.

Here's the JSON object:

{
  "token": "517b27a84a4d373a636e323a9572a0ab43883291", 
  "user": {
    "credential_id":"1",
    "name":"name",
    "password":"password",
    "age":"25",
    "email":"<a href="/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="2a414b464b53... [email protected]</a>",
    "img_src":"043008thmy.jpg",
    "user_type":"0",
    "username":"kalay"
  }
}

Answer №1

To convert JSON into a JavaScript object or array, you can utilize the JSON.parse method.

In this scenario, we are using JSON.parse to parse the JSON data and store it in the json_obj variable.

var json_obj = JSON.parse(json);
var token = json_obj.token;
var username = json_obj.user.username;
var email = json_obj.user.email;

To loop through the key values, you can follow this simple method that checks for "token" and "user" in your JSON data set. It may seem a bit static but works efficiently.

var tokenValue = "",
    userData = {};

for(var keyValue in jsonData){
 if(keyValue === "token"){
    tokenValue = jsonData[keyValue];
 }
 if(keyValue === "user"){
    userData = jsonData[keyValue];
 }
}
