notifications.create()

通知を生成、表示します。

Pass a 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.

If you call notifications.create() more than once in rapid succession, Firefox may end up not displaying any notification at all.

書式

var creating = browser.notifications.create(
  id,                   // optional string
  options               // NotificationOptions
)

パラメータ

idOptional
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.
options
notifications.NotificationOptions. Defines the notification's content and behavior.

返り値

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.

Create and display a basic notification periodically, using an alarm. Clicking the browser action dismisses the notification.

Note that you'll 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.extension.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");
  });
});

Display a similar notification, but add buttons naming cakes, and log the selected cake when a button is clicked:

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;

var buttons = [
  {
    "title": "Chocolate"
  }, {
    "title": "Battenberg"
  }
];

browser.alarms.create("", {periodInMinutes: CAKE_INTERVAL});

browser.alarms.onAlarm.addListener(function(alarm) {
  browser.notifications.create(cakeNotification, {
    "type": "basic",
    "iconUrl": browser.extension.getURL("icons/cake-96.png"),
    "title": "Time for cake!",
    "message": "Something something cake",
    "buttons": buttons
  });
});

browser.browserAction.onClicked.addListener(()=> {
  var clearing = browser.notifications.clear(cakeNotification);
  clearing.then(() => {
    console.log("cleared");
  });
});

browser.notifications.onButtonClicked.addListener((id, index) => {
  browser.notifications.clear(id);
  console.log("You chose: " + buttons[index].title);
});
