Validation for (.) and (,)

Jul 31st, 2008

Hi,

Code below returns true for (.). It should return false like it returns false for (,). Is there any other way to check (.) and (,). I simply want validate money.

Thanks

Try if(!form1.paid.value.match(/^(\d+|\d*\.(\d+))$/)) .

The pattern I posted will only return true for a dot if it has one or more numeric digits after it. Make sure you're actually trying what I posted.
