Need to capture click events on the active tab

[Sanjana Badam]

Hi team, 

I am new to Javascript and I am writing a chrome extension for the first time. 

I have a sample extension for now which displays the active tab url. 

I want to log all the click events on the active tab and store it in a local database. 

1. Is it possible to store to a local database?

2. Can I capture click events or any events for that matter on the active tab? 

3. Also, is it possible for the chrome plug in to access the cookies in the browser? (I think yes, but please correct me if it is not possible).

Thanks,

Sanjana

1. Yes, sort of. Any local storage mechanism that is offered by a web API (cookies, localStorage, sessionStorage, IndexedDB, the deprecated Web SQL Databases or the deprecated FileSystem API) or a Chrome extension API (chrome.storage) is available to extensions. They will not be stored as normal files on the machine of the user, but in very specific files/databases within the profile directory of the user, usually without any human readable names. But, yes, local nonetheless.

2. Yes. Once you manage to figure out how to do that in normal JavaScript/web APIs, coding it using extensions is very similar (they use JavaScript, after all).

3. Yes. The chrome.cookies API lets you access and manipulate cookies.

Hi,

Thank you for your reply.

I was looking into 2. When I was trying to get the elements I was getting it from popup.html (extension one) and not the active tab. I tried using "chrome.tabs.executeScript". Is there something I missed in that?

executeScript is a good way to run scripts in a tab, yep.

Since you cannot access the content of the tab directly, you have to pass a message from the executed script in the tab to the popup page, using chrome.runtime.sendMessage and the like.

See message passing for more information.
