从浏览器检测用户Mac OS X上是否安​​装了应用程序 [英] Detect if application is installed on users Mac OS X from browser

问题描述

如何从浏览器中检测用户Mac OS X上是否安​​装了应用程序.

How can I detect from a browser if an application is installed on a users Mac OS X.

我想实现的是，如果用户单击下载按钮，那么如果他安装了应用程序，它将下载可以用此应用程序打开的特定文件，如果用户没有该应用程序，则他是提示他需要先下载该应用程序才能查看实际文件.

I want to achieve, that if the user clicks the download button then if he has the application installed it downloads a specific file which can be opened with this application, and if the user don't have the application, then he is prompted that he needs to download the application first to view the actual file.
