Field validation

Important for early user feedback is the presence of field validation. USoft 9 has field validation built in by default. An adjusted version of the jQuery validator plug-in is incorporated (jquery.validate.js) to facilitate this. The plug-in comes with a default set of validators. The entire control is well documented at http://jqueryvalidation.org/documentation/.

USoft provides an additional set of validators that can be found in the usoft.ui.validator.js file:

Validator	Explanation
pattern	Allows a field to be validated against a regular expression.
biccode	Checks the field for a valid BIC code
iban	Checks the field for a valid IBAN code
udb‑mandatory	Domain mandatory check
udb-numeric	Domain numeric check
udb-ioformat	Domain IO-format check (not implemented yet)
udb-value-list	Domain allowed values check

When a field is validated as correct the value 'valid' is added to its class list. When validated as invalid the value 'error' is added to its class list. When one of the domain checks are violated the value 'domain-error' is added to the class list. Additionally, an error message is displayed as visual feedback to the user, where applicable.
