javascript - 适用于 JavaScript 的 Google IMA SDK 叠加层和全槽广告参考

Question

我已经在使用Google IMA HTML5 SDK API在我们的自制播放器中显示全幅广告。

现在，我正在尝试在同一个 API 中添加重叠式广告，但我找不到相关文档。FAQ中有一个技术快速入门指南的链接，但事实证明它是为 Flash ActionScript 制作的——但我需要同样的 HTML5/JavaScript 指南。

如何使用 HTML5/JavaScript 实现 Google 重叠式广告和全幅广告？

更新

这是我当前用于两个不同广告请求的 JavaScript 代码（它现在总是为叠加层返回一个空广告，因此它还不起作用）：

var google = google || {
  ima: 'blocked'
}; //AdBlocker
/*
	#################################################################

  'use strict';

全幅广告全屏呈现，带有跳过按钮。您确定要同时渲染覆盖横幅吗？

您将需要两个 adsManager 实例：一个用于全槽，一个用于覆盖。在所需时间，发送两个广告请求，但在其自己的 adsManager 实例中呈现每个广告请求。从理论上讲，您应该首先呈现全幅广告，以便叠加层可以呈现在全幅广告之上。但是，请稍加注意，因为它可能会因多个对象和多个生命周期而变得混乱。另外，请确保您向政策团队明确这一点，因为我不确定叠加广告是否符合政策。
