Question

我是新增的浏览器通知。如何使用浏览器通知？我无法弄清楚从哪里开始。任何人都可以提供关于如何开始这个的建议。

Answer 1

要使浏览器通知正常工作，您的网站或应用程序应通过https提供，否则浏览器不会允许它

mesg = {
   title: "notification title",
   body: "notification body",
   icon: "location to an .ico image",
   timer: true //for auto closing
}

 // Let's check if the browser supports notifications
    if (!('Notification' in window)) {

      console.log('Browser does not support this feature.');

    }else if (Notification.permission === 'granted') {

      Notification.requireInteraction = false;

      if (mesg.title !== 'undefined') {

        const notification = new Notification(mesg.title, {
          body: mesg.body,
          icon: mesg.icon
        });

        if (mesg.timer) {

          setTimeout(function () {
            notification.close();
          }, 5000);
        }

        return notification;

      }// close if undefined

    } else if (Notification.permission !== 'denied') {

      alert('Please click Allow for enabling browser notifications');

      Notification.requestPermission(function (permission) {
        // If the user accepts, let's create a notification
        if (permission === 'granted') {

          if (mesg.title !== 'undefined') {

              const notification = new Notification(mesg.title, {
                body: mesg.body,
                icon: mesg.icon
              });

              if (mesg.timer) {
                setTimeout(function () {
                  notification.close();
                }, 5000);
              }

              return notification;

            }// close if undefined

          } else {

            alert('Permission Denied :[');

          }
        });
      }

我将此用于我的应用程序，您可以重构它以删除重复的代码。

检查Notification API是否有参考资料

代码申请许可

document.addEventListener('DOMContentLoaded', function () {
        if (!Notification) {
            alert('Desktop notifications not available in your browser. Try Chromium.');
            return;
        }

        if (Notification.permission !== "granted")
            Notification.requestPermission();
    });

并显示通知

     if (Notification.permission !== "granted")
                    Notification.requestPermission();
                else {
                    var notification = new Notification('Notification title', {
                        icon: 'Icon Link',
                        body: "Notification Body",
                    });

                    notification.onclick = function () {
                        window.open("Href Here");
                    };

                }

例如

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.
}
notifyMe();
