Struggling to retrieve the value of a JSON key, but it keeps returning empty.
Check out the code snippet below:
let json_=JSON.parse(JSON.stringify(result));
console.log(json_);
console.log(json_.tabs);
console.log(json_["tab"]);
console.log(json_['tab']);
Current output:

Alright, so the scenario is this: you have a variable called json_ which holds an object. When you execute console.log(json_);, the object is printed out with the following value:
{ MUA-S&S 2019...........1 : "{"alwaysOnTop"............................................382}"}This means that within the json object, there is only one property named MUA-S&S 2019...........1 and the corresponding value for this key is
"{"alwaysOnTop............................................382}"console.log(json_.tabs) // undefined
console.log(json_["tab"]); // undefined
console.log(json_['tab']); // undefined
You will receive a value of undefined because your object does not contain any properties named tabs or tab.
Here is the answer :
const tabs = JSON.parse(results[Object.keys(data)[0]])['tabs'];
I found this solution at this website.
