How to negative match regex in JavaScript string replace?

I am trying to replace with a blank all characters except numbers, but this doesn't works:

s.replace(/(?!\d)/g, '')

Thanks!

Use negative character classes:

s.replace(/[^0-9]+/g, '')

or s.replace(/[^\d]+/g, '')

or s.replace(/\D+/g, '')
