Regular expression to remove hostname and port from URL?

Question

I need to write some javascript to strip the hostname:port part from a url, meaning I want to extract the path part only.

i.e. I want to write a function getPath(url

Answer 1

Quick 'n' dirty:

^[^#]*?://.*?(/.*)$

Everything after the hostname and port (including the initial /) is captured in the first group.
