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.

Note that .replace() is a standard JavaScript String method, not a jQuery thing. (I hope you don't mind, but I retagged your question accordingly.) — nnnnnn

THANK YOU!!! so I can keep adding on exceptions like that? This worked. Thank you very much for your help!

@iight: [^...] construction means "match everything except of what is specified in .... In your case [^\w#\/ ] - is "match everything except of \w (letters and underscore), # sign, / sign and a space"

Thank you for the deeper explanation! Do you know what I can search for to learn more about this?

Or MDN for more info about JS's implementation of regex.
