The permission read-only property of the Notification interface indicates the current permission granted by the user for the current origin to display web notifications.

Note : Cette fonctionnalité est disponible via les Web Workers.

Syntax

var permission = Notification.permission;

Value

A DOMString representing the current permission. The value can be:

  • granted: The user has explicitly granted permission for the current origin to display system notifications.
  • denied: The user has explicitly denied permission for the current origin to display system notifications.
  • default: The user decision is unknown; in this case the application will act as if permission was denied.

Examples

The following fairly verbose snippet could be used 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)) {
    console.log("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.permission === "default") {
    Notification.requestPermission(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.
}
