備註

包含媒體元素的應用程式預設會啟用 [播放至]。 如果使用者在執行應用程式時叫用 [裝置 ] 常用鍵，並選取要串流媒體的目標裝置，則 [播放到] 會從目前頁面上的第一個音訊、視訊或影像元素串流媒體。 您可以將 DefaultSourceSelection 屬性設定為 false，以停用此預設行為。

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

您可以在 HTML 標記中新增 -ms-playToDisabled 屬性，以排除預設的 Play To 行為中的個別 HTML 元素。
