我可以确定用户是否启用了浏览器加载项吗？

I am using a PDF viewer in an MVC application, object id='pdfbox'. For this to work an add-on has to be enabled in the browser: Adobe PDF Link Helper.

我在MVC应用程序中使用PDF查看器，对象id ='pdfbox'。为此，必须在浏览器中启用加载项：Adobe PDF Link Helper。

Is it programmatically possible to determine if the add-on is enabled or not in the client machine and give to link to enable the add-on?

是否可以通过编程方式确定客户端计算机中是否启用了加载项，并提供链接以启用加载项？

Is any sample code available?

是否有可用的示例代码？

You could try providing alternate content which will be displayed if the plugin is not installed:

您可以尝试提供备用内容，如果未安装插件，将显示该内容：

<object ...>
    <p>
        You do not have the XXX plugin installed. You could download it here
    </p>
</object>
