Returns an array of
Session
objects, representing windows and tabs that were closed in the current browsing session (that is: the time since the browser was started).
This is an asynchronous function that returns a
Promise
.
var gettingSessions = browser.sessions.getRecentlyClosed(
filter
// optional object
)
filter
可选
对象
。
sessions.Filter
object that limits the set of sessions returned.
A
Promise
. This will be fulfilled with an array of
Session
objects, one for each of the most recently closed tabs or windows in the current browsing session, up to
sessions.MAX_SESSION_RESULTS
or the number included in the
filter
argument, whichever is smaller. The array is given in the reverse of the order in which tabs or windows were closed, so the most recently closed will be at index 0.
If an error occurs, the promise will be rejected with an error message.
BCD tables only load in the browser
This code restores the single most recently-closed session, whether it's a tab or a window:
function restoreMostRecent(sessionInfos) {
if (!sessionInfos.length) {
console.log("No sessions found")
return;
}
let sessionInfo = sessionInfos[0];
if (sessionInfo.tab) {
browser.sessions.restore(sessionInfo.tab.sessionId);
} else {
browser.sessions.restore(sessionInfo.window.sessionId);
}
}
function onError(error) {
console.log(error);
}
browser.browserAction.onClicked.addListener(function() {
var gettingSessions = browser.sessions.getRecentlyClosed({
maxResults: 1
});
gettingSessions.then(restoreMostRecent, onError);
});
