javascript - Saving data in localStorage for a GoogleChrome extension options panel and accessing the data - Stack Overflow

programmeradmin0浏览0评论

I'm making a extension for Google Chrome, the extension deletes all browsing data when the user clicks it, the extension works fine but now im trying to add a options panel where the user can choose which data to delete, my problem is that the options made by the user in the options panel are not being saved (or im not being able to retrieve the data stored in localStorage properly) because when i access the options panel again after saving and closing the checkboxes are blank again.

In addition to the main question i also would like to know which is the best way in your opinion to add the other 14 options to JavaScript [script-options.js] and how would you remend i change the value (true/false) on JavaScript [script.js] using also JavaScript, and ANY advice or remendation about the whole extension code also would be very appreciated.

As always thanks in advance for taking the time to read this, the below list are all the StackOverflow questions and sites i've been reading so far.

Reset to default 4

And here's my contibution.
Done the way it is because I HATE doing html/css ;)
Got auto save on the options so no need for the save button.
Commented out the bit that clears things on the popup press, didnt want to clear anything.

You delete all localstorage data in popup.html. So every time you open it, your settings are gone. If you don't open it, settings are not really usefull.

After going through your code, i prepared a structure which you can further expand for all check boxes;

I have tested it in following cases, let me know if you still have difficulties:

Beginning of page:

After Selection Made

After Page Load:

Refresh:

You can use chrome storage API instead of Local Storage
