These dont work very well. ("hello123").replace( /(^.+\D)(\d+)(\D.+$)/i,'$2') returns "hello124". In fact, none of these work if the number is at the end of the string.

These are way too complicated. "Hello 123 there! 45".match(/\d+/).shift(); works for most needs. Test for null before the .shift() if you're not sure if there's a number in the string.
