I am trying to update my Javascript knowledge,

At the moment I am currently developing a Google Chrome extension, I tried to save some information in the local storage, but of course, the data is deleted after close the browser.

I thought in use chrome.storage however for some stupid reason, is not working (manifiest file edited with storage permissions provided)

here my example code :

chrome.storage.local.set({"SRSaved": "ASDASD"}, function(){});
chrome.storage.local.get("SRSaved", function(result){idList = result;});

If inside the getter function I print the value of result, is a object and the data is there, ok, however the idList value is undefined, is strange, and , of course idList is declared before

Someone can bring me some light with this problem?

  • You are aware that `result` is `{"SRSaved": "ASDASD"}`? Other than that, I'm not seeing what may be off. Could you post more of your code? – Teepeemm Sep 30 '15 at 14:41
