html - Flash 在沙盒属性内的 iframe 中不起作用

Question

我使用 iframe 来显示一些页面。这些页面可能包含 adobe flash 内容，例如视频。我的问题是 abode flash 没有在 sandbox 属性内的 iframe 中执行。我的 iframe 标签:

<iframe sandbox="allow-popups allow-pointer-lock allow-same-origin allow-forms allow-scripts" src="http://example.com"></iframe>

简短回答:您不能在沙盒 iframe 中执行 flash 插件。

规范:http://www.w3.org/TR/html5/embedded-content-0.html#attr-iframe-sandbox

Plugins that cannot be secured are disabled in sandboxed browsing contexts because they might not honor the restrictions imposed by the sandbox (e.g. they might allow scripting even when scripting in the sandbox is disabled). User agents should convey the danger of overriding the sandbox to the user if an option to do so is provided.
