HTML5-推送状态桌面通知

Question

Suppose I want to create a status report notification that check the db from time to time of the current status? Example: Lets say, a computer shop scenario that will show notifications 5 minutes before -- alerting the admin that the time of PC 1 is about to run out.

I tried following this tutorial, http://beakkon.com/tutorial/html5/desktop-notification , but it needs user interaction (in this case, button click) so that desktop notifications will appear. I am using PHP, jQuery, HTML as my web technology.

Also, Will the notification still appear even if I am not on the web page triggering the fetching of data?

Answer 1

Thanks to zvona for guiding the way. The trick will be to put the notification in a page that will be accessible by other pages in that way, notification will be accessible anywhere.

Answer 2

Desktop notifications require user interaction first time, in order to allow them.

But basically you create a setInterval which makes the DB query / XHR and then triggers createNotification if certain conditions are met.
