使用 JavaScript 的插播式廣告範例程式碼

警告

自 2020 年 6 月 1 日起，Windows UWP 應用程式的 Microsoft 廣告收益平台將會關閉。深入了解

本主題提供顯示插播式廣告的基本 JavaScript 和 HTML 通用 Windows 平台 (UWP) 應用程式的完整範例程式碼。如需示範如何設定專案以使用此程式碼的逐步指示，請參閱插播式廣告。如需完整的範例專案，請參閱 GitHub 上的廣告範例。

程式碼範例

本節說明在顯示插播式廣告的基本應用程式中 HTML 和 JavaScript 檔案的內容。若要使用這些範例，請將此程式碼複製到 Visual Studio 中的 JavaScript WinJS 應用程式 (通用 Windows) 專案。

此範例應用程式會使用兩個按鈕來要求，然後推出插播式廣告。 Visual Studio 所產生的 main.js 和 index.html 檔案已經過修改，如下所示。下列 script.js 檔案包含範例中大部分的程式碼，您應該將此檔案新增至專案中的 js 資料夾。

將應用程式提交至市集之前，將 applicationId 和 adUnitId 變數的值取代為合作夥伴中心的即時值。如需詳細資訊，請參閱在您的應用程式中設定廣告單元。

注意

若要更改此範例以顯示插播式橫幅，而不是插播式影片廣告，請將 InterstitialAdType.display 值傳遞至 RequestAd 方法的第一個參數，而不是 InterstitialAdType.video。如需詳細資訊，請參閱插播式廣告。
