RE <一个href=\"http://stackoverflow.com/questions/76179/how-to-determine-if-the-users-browser-can-view-pdf-files#76220\">dawnerd:插件检测是不正确的答案。我没有安装在我的浏览器（Firefox在Ubuntu）一个PDF插件，但我能够使用的操作系统的文档查看器（不使用Acrobat Reader）来查看PDF文件。

Re dawnerd: Plug-in detection is not the right answer. I do not have a PDF plugin installed in my browser (Firefox on Ubuntu), yet I am able to view PDF files using the operating system's document viewer (which is not Acrobat Reader).

今天，任何操作系统，可以运行网络浏览器可以查看PDF文件的开箱。

Today, any operating system that can run a web browser can view PDF files out of the box.

如果一个特定的系统没有一个PDF浏览器安装并配置为使用它的浏览器，则可能意味着要么它是一个手工制作安装Windows，一个很下调备用操作系统或东西真的复古的。

If a specific system does not have a PDF viewer installed and the browser configured to use it, that likely means that either it's a hand-made install of Windows, a very trimmed down alternate operating system, or something really retro.

这是合理的假设，在任何这些情况下，用户会知道什么是PDF文件，要么故意选择不能够查看他们或不知道如何安装所需的软件。

It is reasonable to assume that in any of those situation the user will know what a PDF file is and either deliberately choose not to be able to view them or know how to install the required software.

如果我欺骗我自己，我很想把它给我解释以何种方式我错了。

If I am deluding myself, I would love to have it explained to me in which way I am wrong.
