HTML5 Desktop Notification Demo and Detailed Explanation

Hello everyone! Today I will show you how to implement desktop notifications using HTML5 and a small amount of JavaScript code through a simple demonstration. GitHub project

HTML5 desktop reminder background information

Notifications allow users to be reminded outside the context of the web page, such as the delivery of emails.

You can display, queue and replace notifications. You can also add an icon to the message body on the left side that appears on the left side of the message body. You can also use the tag member for multiple instantiation (the result of this case is a notification; the second notification replaces the first notification with the same tag). [Learn more about the W3C Web Notifications API] (The W3C Web Notifications API link should be inserted here).

According to my tests, you can only display up to 4 reminders at a time and they will be queued, so when you turn off one, the next one will be displayed, and so on. Also, you can't put hyperlinks in it (this would be a great feature). The appearance of desktop reminders is shown below.

As with most of these features, you will be prompted to authorize for security reasons.
