How to get the #fragment identifier part of an URL

Question

In Phoenixframework I want to know full URL path that is being requested so I tried to use <%= @conn.request_path %>. The problem is that I'm requesting :/spa.html#pageone and I'm getting only /spa.html. What is the correct way of also getting the #fragment identifier part of it?

Answer 1

The fragment is not available on the server side.

From RFC2396

When a URI reference is used to perform a retrieval action on the identified resource, the optional fragment identifier, separated from the URI by a crosshatch ("#") character, consists of additional reference information to be interpreted by the user agent after the retrieval action has been successfully completed. As such, it is not part of a URI, but is often used in conjunction with a URI.

You can access it in JavaScript with window.location.hash.
