The click event of the Notification interface fires when the user clicks on displayed Notification.

The default behavior is to move the focus to the viewport of the notification's related browsing context. If you don't want that behavior, call preventDefault() on the event object.

Use the event name in methods like addEventListener(), or set an event handler property.

addEventListener("click", (event) => {});

onclick = (event) => {};

A generic Event.

In the following example, we use an onclick handler to open a webpage in a new tab (specified by the inclusion of the '_blank' parameter) once a notification is clicked:

notification.onclick = (event) => {
  event.preventDefault(); // prevent the browser from focusing the Notification's tab
  window.open("http://www.mozilla.org", "_blank");
};
