Can someone tell what the /\D/g.'' mean in newValue.replace(/\D/g,'')

[wbrown1]

Can someone tell what the  /\D/g.'' mean in  newValue.replace(/\D/g,'') and what other option there are or where the documentation could be found. I am trying to use this to force the client to enter a whole number and no decimals.
