Reliably Dismissing Webkit Notifications
html, html5-notifications, javascript
Solution
Use a window.onunload or window.onbeforeunload handler to clear the noifications when the page is closed. This does not preserve the three-second delay, however, since notifications will be closed immediately when the page closes.
Another option (that does preserve the three-second delay) is to create the notifications from HTML pages using `createHTMLNotification(url)`. Have the notification page close itself by including a script like `setTimeout(window.close, 3000)` within the notification HTML document. In this case, obviously, you don't need a `setTimeout` call in your main page, since it is already included in the notification.
Problem
I'm successfully creating and dismissing webkit notifications like so: ``` notification = window.webkitNotifications.createNotification('foo.png', 'bar', 'baz') notification.show() setTimeout -> notification.cancel() , 3000 ``` However, the notifications aren't dismissed if the user closes or refreshes the page during those three seconds, and they stay on the desktop until manually closed. Is there a way to reliably dismiss them under these circumstances?
