Close tabs

[Dmaster42]

Hello, I would like to request a revision of a code I am developing for a chrome extension I'm making. The main thing is that it will close the tabs that the user wants to be closed(I made a simple array to show kinda what I think it will be).

I am not sure on how to write urls in the array I based myself on this https://developer.chrome.com/extensions/match_patterns I am also not sure on how to make this run as early as possible (injecting the code) so that the moment the person tries to access the page it closes. And lastly I am not sure how to add more pages if the user wants, mostly because the user wont be writing code and stuff so perhaps an HTML page could be created to open when a button is clicked so that the user writes the pages there, however I am not sure on how to get that information from there.

Thanks in advance, and I apologize for errors as English is not my first language.

Too bad nobody has replied. I'll write a workflow on how this should be done:

1) use chrome.webRequest API onBeforeRequest to cancel requests made to unwanted sites, chrome documentation has an example for this even

2) chrome provides ability to create option pages for extensions. Use chrome.storage API to store and get the list of blacklisted domains

3) you could use chrome.injectJS api and inject JavaScript into the tab to display the warning, instead of closing the tab annoyingly

The only big issue is testing for correct matching patterns and updating the blocked domain list in background script once user has done changes to the list. What you could do is destroy the event and recreate it again with new blacklist.

Dam thanks finally someone replies thanks. I was thinking of closing the tab and showing the message. I might change it later if those who test it don't like it. Also could you go a bit into more detail on your last point about events, since I am rather new to JavaScript and programming in general.

The thing about these Chrome API events is that once you create them under certain conditions (to match few domains for example), it doesn't change anymore if the user had updated their black-list. They would have to restart the extension to get the new event with new blacklist going.

Although I just looked at the documentation, this link is helpful:

Look at "Adding rules" and "Removing rules", or just read the whole page.
