Does a browser download JS files if the user has JS disabled?

Does a browser download JS files if the user has JS disabled?

I'm wondering if the browser downloads the JS files and ignores them or ignores the download all together.

Do different browsers act differently in this case?

Edit:

I asked a follow up question to this question here.

Some testing (on Ubuntu 10.04) so far yields

  • Opera: doesn't download (disabled JS in preferences)
  • Firefox: doesn't download (disabled JS in preferences or with NoScript)
  • Google Chrome/Chromium: downloads (disabled JS via -disable-javascript parameter)
  • SRWare Iron (Chrome without the nonsense): doesn't download (disabled JS via "Options" - "Under The Hood" - "Content Settings" - "JavaScript" - "Content Settings" - "Do not allow any site to run JavaScript")
  • IE 8: doesn't download
  • IE 7: downloads

The best way to find out something like this is to use a tool like fiddler With this tool you can examine a web request and see exactly what is going on. As Nick says above different browsers may act differently, but at least this will let you know for sure.
