Notification.requestPermission()

Note: This feature is available in Web Workers.

Secure context
This feature is available only in secure contexts (HTTPS), in some or all supporting browsers.

The requestPermission() method of the Notification interface requests permission from the user for the current origin to display notifications.

Note: This feature is not available in SharedWorker

Syntax

The latest spec has updated this method to a promise-based syntax that works like this:

Notification.requestPermission().then(function(permission) { ... });

Previously, the syntax was based on a simple callback; this version is now deprecated:

Notification.requestPermission(callback);

Note: Safari still uses the callback syntax to get the permission. Read Using the Notifications API for a good example of how to feature detect this and run code as appropriate.

Parameters

callback Optional Deprecated since Gecko 46
An optional callback function that is called with the permission value. Deprecated in favor of the promise return value.

Returns

A Promise that resolves to a DOMString with the permission picked by the user. Possible values for this string are:

  • granted
  • denied
  • default

Examples

Assume this basic HTML:

<button onclick="notifyMe()">Notify me!</button>

It's possible to send a notification as follows — here we present a fairly verbose and complete set of code you could use if you wanted to first check whether notifications are supported, then check if permission has been granted for the current origin to send notifications, then request permission if required, before then sending a notification.

function notifyMe() {
  // Let's check if the browser supports notifications
  if (!("Notification" in window)) {
    alert("This browser does not support desktop notification");
  }

  // Let's check whether notification permissions have already been granted
  else if (Notification.permission === "granted") {
    // If it's okay let's create a notification
    var notification = new Notification("Hi there!");
  }

  // Otherwise, we need to ask the user for permission
  else if (Notification.permission !== "denied") {
    Notification.requestPermission().then(function (permission) {
      // If the user accepts, let's create a notification
      if (permission === "granted") {
        var notification = new Notification("Hi there!");
      }
    });
  }

  // At last, if the user has denied notifications, and you 
  // want to be respectful there is no need to bother them any more.
}

We no longer show a live sample on this page, as Chrome and Firefox no longer allow notification permissions to be requested from cross-origin <iframe>s, with other browsers to follow. To see a example in action, check out our To-do list example (also see the app running live.)

Note: In the above example we spawn notifications in response to a user gesture (clicking a button). This is not only best practice — you should not be spamming users with notifications they didn't agree to — but going forward browsers will explicitly disallow notifications not triggered in response to a user gesture. Firefox is already doing this from version 72, for example.
