Google AMP - 用户通知
Google amp-user-notification 用于向用户显示可关闭的对话框消息。我们可以使用它来通知用户有关页面上的 cookie。
要使用 amp-user-notification，我们需要在页面上添加以下脚本 −
<script async custom-element = "amp-user-notification"
src = "https://cdn.ampproject.org/v0/amp-user-notification-0.1.js">
</script>
Amp-user-notification 标签格式 −
<amp-user-notification id = "my-notification" layout = "nodisplay">
<div>Example of amp-user-notification.
<button on = "tap:my-notification.dismiss">I accept
</button>
</div>
</amp-user-notification>
让我们通过一个实际示例了解 amp-user-notification −

<h3>Google AMP - Amp User Notification</h3>
<amp-user-notification
id = "my-notification"
layout = "nodisplay">
<div>Example of amp-user-notification.
<button on = "tap:my-notification.dismiss">I accept
</button>
</div>
</amp-user-notification>

输出
上面给出的工作示例代码的输出如下所示 −
一旦用户点击按钮，通知就会被关闭。一旦关闭，即使您重新加载页面也不会显示通知。
用户通知的数据存储在浏览器 localStorage 中。如果清除 localstorage 并刷新页面，您将能够再次看到通知。您可以在浏览器控制台中使用 localStorage.clear() 尝试相同的操作。
使用 dismiss 操作可以关闭通知，方法是在按钮上使用以下操作
<button on = "tap:my-notification.dismiss"> I accept </button>
当用户点击按钮时，通知将被关闭。
