thank you!
for me it work just "window.onload = function()"
Hello.
I have no used this API yet, so here's a super newbie-question.
Will sync "actually" sync the data between different systems? Or is it just a local thing?
@phaistonian
Hi, its exactly a sync among machines with the same Google account.
@phaistonian it attempts to sync across other Chrome browsers and devices associated with the current user's account. If that person does not have an account linked to Chrome or they have not given Chrome sync permissions, it will store locally until they have given sync permissions or log in.
@IzumiSy Is there a way to extend this to have three fields? I'm struggling trying to do it!
Thank you for this short & sweet example
@Cormaca18
chrome.storage.sync.set takes an Object as the first argument. You can probably add some more keys as you want.
chrome.storage.sync.set({
"data1": data1,
"data2": data2,
"data3": data3
}, function() {
...
});
Why is it that when I stored a new item the old one is removed?
Is there no way to retain the old entries?
@IzumiSy
Also, is there a way to perform CRUD operation using the chrome storage API?
Is there no way to retain the old entries?
It looks no way to do that without writing your own update logic like renaming the key of the value in updating with a new key-value pair.

No, there isn't. Chrome.storage.sync only provides simple set/get methods. If you want to do that, you need to write your own CRUD operation logics.
Thanks! I solved my problem
window.close(); this function had using method close to sync data? I have issues when user type in textarea and must sync without close popup.html of extension. Anyone has meet same issues? @IzumiSy
@iletai No, you don't have to put window.close(). That method is only for closing popup here, not for any finalizing.

@maskmanlucifer I have trouble using chrome.storage, but maybe your issue comes from the fact that you didn’t write "permissions": ['storage'] in the manifest.json file
Thank u <3
what different between
chrome.runtime.lastErrorandchrome.runtime.error? i only seechrome.runtime.lastErrorproperty in official docs.
