[facebook] Facebook share link without JavaScript

Lots of these answers no longer apply, so here's mine:

Use the Share Dialog described at the Facebook Dev Page.

Example:

https://www.facebook.com/dialog/share?
  app_id=<your_app_id>
  &display=popup
  &href=https%3A%2F%2Fdevelopers.facebook.com%2Fdocs%2F
  &redirect_uri=https%3A%2F%2Fdevelopers.facebook.com%2Ftools%2Fexplorer

But you have to put in your registered app_id, the href, and a redirect uri.
