注解

默认情况下，包含媒体元素的应用已启用“播放到”。 如果用户在运行应用时调用“ 设备” 超级按钮，并选择要将媒体流式传输到的目标设备，则“播放到”将从当前页上的第一个音频、视频或图像元素流式传输媒体。 可以通过将 DefaultSourceSelection 属性设置为 false 来禁用此默认行为。

var ptm = Windows.Media.PlayTo.PlayToManager.getForCurrentView();
ptm.defaultSourceSelection = false;

通过在 HTML 标记中添加 -ms-playToDisabled 属性，可以从默认的“播放到”行为中排除单个 HTML 元素。

<video src="http://www.example.com/videos/video.mp4" x-ms-playToDisabled/>
