Cross Field Validation
Sunday August 17, 2008
Sometimes the valid values for one form field depend on the value of another field
In the last (for now) JavaScript tutorial on form field validation we consider the need to validate fields together. Once you have individually validated each of the fields on your form and know that they all contain values that are valid for the field you then need to consider if that value is also valid when the other fields on the form contain the values that they contain.
