1,Notification api的通知接口,用于显示桌面通知;
2,代码:
function Notice() {
if (!("Notification" in window)) {
// Check if the browser supports notifications
alert("This browser does not support desktop notification");
} else if (Notification.permission === "granted") {
// Check whether notification permissions have already been granted;
// if so, create a notification
const notification = new Notification("通知!");
console.log(notification);
} else if (Notification.permission !== "denied") {
// We need to ask the user for permission
Notification.requestPermission().then((permission) => {
// If the user accepts, let's create a notification
if (permission === "granted") {
const notification = new Notification("通知!");
}
});
}
// At last, if the user has denied notifications, and you
// want to be respectful there is no need to bother them anymore.
}
