Clears a notification, given its ID.
This is an asynchronous function that returns a
Promise
.
var clearing = browser.notifications.clear(
id
// string
)
id
string
. The ID of the notification to clear. This is the same as the ID passed into
notifications.create()
's callback.
A
Promise
that will be fulfilled with a boolean:
true
if the notification was cleared, or
false
if it was not (for example, because the notification referenced by
id
did not exist).
BCD tables only load in the browser
This example shows a notification when the user clicks a browser action, unless the notification was already being shown, in which case it clears the notification:
var myNotification = "my-notification";
function toggleAlarm(all) {
if (myNotification in all) {
browser.notifications.clear(myNotification);
} else {
browser.notifications.create(myNotification, {
"type": "basic",
"iconUrl": browser.runtime.getURL("icons/cake-48.png"),
"title": "Am imposing title",
"message": "Some interesting content"
});
}
}
function handleClick() {
var gettingAll = browser.notifications.getAll();
gettingAll.then(toggleAlarm);
}
browser.browserAction.onClicked.addListener(handleClick);
