检测 chrome.tabs 事件源

Question

I am working on chrome extension that deals with tabs. The extension allows to open and close tabs.
I also need to know when a tab had opened and closed outside of my extension, so I listen to tabs.onClose and tabs.onCreate events. My question is how can I determine easily whether an open tab action happened in my extension or outside of it?

Answer 1

Basically you can not do this easily, because tab event does not have something like event resource to let you track who make changes to the tabs

My idea is:

• define an array in your background script which keeps all the tab id that your extension changed.

• listen to onUpdated , onCreated , and all other tab events that you want to listen to

• check if the tab id in that array, if not, then it's not changed by your extension.
