JSON value parsing problem Chrome Extension

Question

Trying to access JSON key value, but it gives me nothing .

Here is the code :

                    let json_=JSON.parse(JSON.stringify(result));
                    console.log(json_);
                    console.log(json_.tabs);
                    console.log(json_["tab"]);
                    console.log(json_['tab']);

Here is what I get :

Here is a snap for detailed output :

The object printed to the console has only one key and that is neither tabs or tab. — Titus

Your value inside is a string (see the double quote marks), not an object. You should fix your code that generates the value. Start by removing all JSON.stringify and JSON.parse. — woxxom

Ok, The thing is you have variable json_ whose value is an object when you do console.log(json_); the object gets print and the value of that object is:

{ MUA-S&S 2019...........1 : "{"alwaysOnTop"............................................382}"}

That is you have only one property inside the json object that is MUA-S&S 2019...........1 and the value of this key is"{"alwaysOnTop............................................382}" which is a string when you are trying to do :

console.log(json_.tabs) // undefined
console.log(json_["tab"]); // undefined
console.log(json_['tab']); // undefined

the value you get is undefined as your object does not have any property with name tabs,tab

Here is the solution :

let tabs_=JSON.parse(result[Object.keys(result)[0]])['tabs'];

I got this from here.

And here is my project, if anyone is interested, feel free to contribute.
