[Vtigercrm-developers] extend Validation engine

[Uma S]

Sure Alan! you can handle this define the custom validation that need to be
performed in module specific js file which should extend standard validator
(Vtiger_PhoneValidator_Js). So that during validation you can call parent
class validate() api to perform standard validation on field.

For example : Please check Vtiger_Percentage_Validator_Js in
FieldValidator.js (modules/Vtiger/resources/Validator) which is making use
of Positive number validator.

Hope, I made the point clear.
