Class TCustomValidator

Description

TCustomValidator class

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 OnServerValidate event that performs the validation. The data string of the input control to validate can be accessed by TServerValidateEventParameter::getValue of the event parameter. The result of the validation should be stored in the TServerValidateEventParameter::getIsValid 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:

  1. <script type="text/javascript"><!--
  2. function ValidationFunctionName(sender, parameter)
  3. {
  4. // if(parameter == ...)
  5. // return true;
  6. // else
  7. // return false;
  8. }
  9. --></script>
Use the ClientValidationFunction property to specify the name of the client-side validation script function associated with the TCustomValidator.

Class Description
TActiveCustomValidator TActiveCustomValidator Class
Method Summary
boolean evaluateIsValid ()
string getClientClassName ()
boolean onServerValidate (string $value)
void setClientValidationFunction (string $value)
Methods
evaluateIsValid (line 89)

This method overrides the parent's implementation.

The validation succeeds if onServerValidate returns true.

  • return: whether the validation succeeds
  • access: public
boolean evaluateIsValid ()

Redefinition of:
TBaseValidator::evaluateIsValid()
This is the major method for validation.
getClientClassName (line 62)

Gets the name of the javascript class responsible for performing validation for this control.

This method overrides the parent implementation.

  • return: the javascript class name
  • access: protected
string getClientClassName ()

Redefinition of:
TBaseValidator::getClientClassName()
Gets the name of the javascript class responsible for performing validation for this control.

Redefined in descendants as:
getClientScriptOptions (line 116)

Returns an array of javascript validator options.

  • return: javascript validator options.
  • access: protected
array getClientScriptOptions ()

Redefinition of:
TBaseValidator::getClientScriptOptions()
Returns an array of javascript validator options.

Redefined in descendants as:
getClientValidationFunction (line 70)
  • return: the name of the custom client-side script function used for validation.
  • access: public
string getClientValidationFunction ()
onServerValidate (line 104)

This method is invoked when the server side validation happens.

It will raise the OnServerValidate event. The method also allows derived classes to handle the event without attaching a delegate. Note The derived classes should call parent implementation to ensure the OnServerValidate event is raised.

  • return: whether the value is valid
  • access: public
boolean onServerValidate (string $value)
  • string $value: the value to be validated
registerClientScriptValidator (line 128)

Only register the client-side validator if setClientValidationFunction is set.

  • access: protected
void registerClientScriptValidator ()

Redefinition of:
TBaseValidator::registerClientScriptValidator()
Registers the individual validator client-side javascript code.
setClientValidationFunction (line 79)

Sets the name of the custom client-side script function used for validation.

  • access: public
void setClientValidationFunction (string $value)
  • string $value: the script function name
