RegExp for validating PRICE [closed]

Answer 1

This regex ought to do it:

^[\d\.,]+$

Edit:

Here's a better regex, to allow more sane number formats (for US dollars). Still not perfect - would need to know exactly what validation you are expecting, if this isn't quite it.

^(\d{1,3})?(,?\d{3})*(\.\d{2})?$
