HTML5桌面通知Notification

这是一个可让网页在最小化时仍能够显示通知的api

效果的话能够看这个论坛的效果，登陆进去肯定给权限，等有人发消息就能够看到效果了

右下角，

这样在网页外面的一个通知的效果

这样在浏览器没有打开，焦点不在咱们的网页的时候也是能够发通知让用户看到的。

 

使用的话要先申请权限

贴一段基本的示例代码

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(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.
}
