How can I get the URL fragment?

[bnctth]

I can't seem to find a way to extract the URL fragment (the thing after the #) anywhere. I'm trying to get it in a load function (or hook if necessary). Thanks

if you want to get it on the server (SSR), that's a no, client side you can get it via url.hash I believe.

"The search part, if present, is
sent as part of the HTTP command, and may in this respect be
treated as part of the path. No fragmentid part of a WWW URI (the
hash sign and following) is sent with the request. Spaces and
control characters in URLs must be escaped for transmission in
HTTP, as must other disallowed characters. "
