notifications.clear()

Clears a notification, given its ID.

This is an asynchronous function that returns a Promise.

Syntax

let clearing = browser.notifications.clear(
  id                            // string
)

Parameters

id: string. The ID of the notification to clear. This is the same as the ID passed into notifications.create()'s callback.

Return value

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).

Examples

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:

let 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() {
  let gettingAll = browser.notifications.getAll();
  gettingAll.then(toggleAlarm);
}

browser.browserAction.onClicked.addListener(handleClick);
