How to get the value of a variable from storage?

Question

JavaScript

There is a function:

function getTokenFromStorage() {
    var key = 'key-aaa';
    var value = 'value-bbb';

    chrome.storage.local.set({'key-aaa': value});

    chrome.storage.local.get(key,function(result){
      alert(result[key]);
    });
}

How can I make this function return the value stored in result[key]?

Answer 1

Perhaps I did not quite understand the question, do you mean this?

function getTokenFromStorage() {
    ...
    var resultValue;
    chrome.storage.local.get(key,function(result){
        resultValue = result[key];
    });
    return resultValue;
}
