PHP Класс Prado\Web\UI\WebControls\TCustomValidator

TCustomValidator performs user-defined validation (either server-side or client-side or both) on an input component. To create a server-side validation function, provide a handler for the {@link onServerValidate OnServerValidate} event that performs the validation. The data string of the input control to validate can be accessed by {@link TServerValidateEventParameter::getValue Value} of the event parameter. The result of the validation should be stored in the {@link TServerValidateEventParameter::getIsValid IsValid} property of the event parameter. To create a client-side validation function, add the client-side validation javascript function to the page template. The function should have the following signature: Use the {@link setClientValidationFunction ClientValidationFunction} property to specify the name of the client-side validation script function associated with the TCustomValidator.
