Numbers are alphanumeric.

Everything you can type is a string so that prompt wouldn't help anyone.

Anyway, don't do that. Use standard web interface so that your application works as the users expect. For example,

- Set the border of each text field to red and change to black when the field has correct data type in it.
- Use a tooltip to explain the input requirements.
- Disable Confirm Order until all the fields pass the data validation criteria.
