As a Google Chrome extension, is it possible to listen to tab switches? That is, to be notified when a tab switch has just happened?
(I want to make an extension that, in fullscreen, when switching tabs with the usual Ctrl + PageUp and Ctrl + PageDown keyboard shortcuts, gives visual feedback of the switch and other currently available tabs.)
In your manifest.json file add the following:
"permissions":[
"background",
"tabs"
],
"background" : {
"scripts": ["scripts/background.js"],
"persistent": false
}
In your background.js:
chrome.tabs.onActivated.addListener(function(activeInfo) {
console.log(activeInfo.tabId);
});
note: tab url may not be available when using chrome.tabs.onActivated
so use chrome.tabs.onUpdated instead.
