Besides of the built-in field validation, DB-Views supports the following input validation methods:

  • Text fields can be validated by defining an input pattern. (e.g., zip codes)
  • Text fields can also be validated by specifying a JavaScript regular expression. This expression is evaluated whenever the end-user types a character.
  • A JavaScript validation snippet can be defined on all field types.  This snippet is executed whenever the end-user types a character providing a powerful and detailed error detection.
  • Cross-field validation is done by specifying a form-level JavaScript snippet. This snippet is executed when the end-user submits the form.
