可靠地解除Webkit通知 [英] Reliably Dismissing Webkit Notifications

问题描述

我正在成功创建和解除webkit通知，如下所示：

  notification = window.webkitNotifications.createNotification（'foo。 png'，'bar'，'baz'）
 notification.show（）
 setTimeout  - > 
 notification.cancel（）
，3000 
  

但是，通知不是'如果用户在这三秒钟内关闭或刷新页面，则会被解雇，并且他们会一直停留在桌面上，直到手动关闭。

有没有办法可靠地解雇他们使用 window.onunload 或 window.onbeforeunload 处理程序，用于在页面关闭时清除通知。但是，这不会保留三秒钟的延迟，因为通知将在页面关闭时立即关闭。

另一个选项（ 保留三秒延迟）是使用 createHTMLNotification（url）从HTML页面创建通知。通过在通知HTML文档中包含 setTimeout（window.close，3000）等脚本，让通知页面关闭本身。在这种情况下，显然，您的主页中不需要 setTimeout 调用，因为它已包含在通知中。

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?

解决方案

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.
