history.onTitleChanged
Fired when the title of a page visited by the user is recorded.
To listen for visits to a page you can use
history.onVisited
. However, the history.HistoryItem
that this event passes to its listener does not include the page title, because the page title is typically not known at the time history.onVisited
is sent.Instead, the stored
history.HistoryItem
is updated with the page title after the page has loaded, once the title is known. The history.onTitleChanged event is fired at that time. So if you need to know the titles of pages as they are visited, listen for history.onTitleChanged
.Syntax
browser.history.onTitleChanged.addListener(listener)
browser.history.onTitleChanged.removeListener(listener)
browser.history.onTitleChanged.hasListener(listener)
Events have three functions:
addListener(listener)
- Adds a listener to this event.
removeListener(listener)
- Stop listening to this event. The
listener
argument is the listener to remove. hasListener(listener)
- Check whether
listener
is registered for this event. Returnstrue
if it is listening,false
otherwise.
