Creates and displays a notification.
传递
notifications.NotificationOptions
to define the notification's content and behavior.
You can optionally provide an ID for the notification. If you omit the ID, an ID will be generated. You can use the ID to
update
or
clear
the notification.
This is an asynchronous function that returns a
Promise
.
警告：
若调用
notifications.create()
more than once in rapid succession, Firefox may end up not displaying any notification at all.
var creating = browser.notifications.create(
id, // optional string
options // NotificationOptions
)
id
可选
string
. This is used to refer to this notification in
notifications.update()
,
notifications.clear()
, and event listeners. If you omit this argument or pass an empty string, then a new ID will be generated for this notification. If the ID you provide matches the ID of an existing notification from this extension, then the other notification will be cleared.
选项
notifications.NotificationOptions
. Defines the notification's content and behavior.
A
Promise
that will be fulfilled when the notification is created and the display process has been started, which is before the notification is actually displayed to the user. It is fulfilled with a string representing the notification's ID.
This example displays a notification periodically, using
alarm
. Clicking the browser action dismisses the notification. You need the "alarms"
permission
to create alarms (as well as the "notifications" permission to create notifications).
var cakeNotification = "cake-notification"
/*
CAKE_INTERVAL is set to 6 seconds in this example.
Such a short period is chosen to make the extension's behavior
more obvious, but this is not recommended in real life.
Note that in Chrome, alarms cannot be set for less
than a minute.
*/
var CAKE_INTERVAL = 0.1;
browser.alarms.create("", {periodInMinutes: CAKE_INTERVAL});
browser.alarms.onAlarm.addListener(function(alarm) {
browser.notifications.create(cakeNotification, {
"type": "basic",
"iconUrl": browser.runtime.getURL("icons/cake-96.png"),
"title": "Time for cake!",
"message": "Something something cake"
});
});
browser.browserAction.onClicked.addListener(()=> {
var clearing = browser.notifications.clear(cakeNotification);
clearing.then(() => {
console.log("cleared");
});
});
