Add exception to regex

Question

I'm using this code I stumbled upon to 'clean up' urls with jquery:

.replace(/[^\w ]+/g,'') // and
.replace(/ +/g,'-')

The first one removes non alpha-numeric characters, while the second turns spaces into a dash

My question is: Is there a way to exclude a character, in my situation, # , from this first .replace() ?

Thank you.

Answer 1

.replace(/[^\w#\/ ]+/g,'') // and
