I have a website for an application I've developed, which is compiled for a variety of operating systems. On the downloads page, I would like to have it arranged so that the download link for the user's OS is at the top with a big obvious "Download!" button, with the other options listed below in plainer links. How can I do this?

  • Look into `navigator.userAgent` and the `User-Agent` header. – tcooc Aug 12 '14 at 23:08

When you log window in Mozilla's developer console you can see all the properties of window, this is quite useful and fun to find new things.

When I did so there is a property called navigator, and within that platform.

So, since I was running Linux when I did this, the value of window.navigator.platform was equal to "Linux".

One easy way you could do this is:

document.getElementById("download_btn").setAttribute("href","downloads/package_" + window.navigator.platform + ".zip");

So, if I were to download it off your site, I would download the file "package_Linux.zip".

Type navigator in your javascript console and check out all the goodies you have access to. In particular, userAgent and platform.

Combine that with some regex matches and the help of user agent strings list and you're good to go.
