示例
以下示例使用 TileNotification 构造函数创建新实例,然后使用 ExpirationTime 属性显示 30 秒的磁贴通知。
function tileNotificationExpiration() {
var Notifications = Windows.UI.Notifications;
var tileXml = Notifications.TileUpdateManager.getTemplateContent(Notifications.TileTemplateType.tileWide310x150Text04);
var currentTime = new Date();
var seconds = 30;
var tileTextAttributes = tileXml.getElementsByTagName("text");
tileTextAttributes[0].appendChild(tileXml.createTextNode("This notification will expire at " + new Date(currentTime.getTime() + seconds * 1000)));
var tileNotification = new Notifications.TileNotification(tileXml);
// Set the expiration time on the notification
var expiryTime = new Date(currentTime.getTime() + seconds * 1000);
tileNotification.expirationTime = expiryTime;
Notifications.TileUpdateManager.createTileUpdaterForApplication().update(tileNotification);
}
构造函数
TileNotification(XmlDocument) |
创建并初始化 TileNotification 对象的新实例,以便与 TileUpdater 一起使用。 |
属性
Content |
获取通知内容的 XML 说明,然后可以对其进行操作以更改通知。 |
ExpirationTime |
获取或设置 Windows 从磁贴中删除通知的时间。 默认情况下,磁贴更新不会过期。 最佳做法是显式设置过期时间以避免过时的内容。 |
Tag |
获取或设置一个字符串,Windows 可以使用该字符串来防止重复的通知内容出现在队列中。 |
