A classe Validator é feita para validar campos em Flex. Apesar de existir vários validadores por padrão, como de cartão de crédito e mail, não existem os de CPF e CNPJ. Fiz um validador para as duas, ambas com teste unitário:
CNPJ:
package br.com.nuccitelli.validator {
import mx.utils.ObjectUtil;
import mx.validators.ValidationResult;
import mx.validators.Validator;
public class CNPJValidator extends Validator {
static protected const FIRST_VERIFIER_DIGITS:Array=[ 5,4,3,2,9,8,7,6,5,4,3,2 ];
static protected const SECOND_VERIFIER_DIGITS:Array=[ 6,5,4,3,2,9,8,7,6,5,4,3 ];
override protected function doValidation(value:Object):Array {
var results:Array=[];
// Call base class doValidation().
results=super.doValidation(value);
// Return if there are errors.
if(results.length>0)
return results;
// Check first name field.
var cnpj:String=value as String;
if(cnpj==null||cnpj=="") {
return results;
} else if(cnpj.length!=14) {
results.push(new ValidationResult(true,"","","O CNPJ deve conter 14 dígitos"));
return results;
} else if(!verifyDigits(cnpj)) {
results.push(new ValidationResult(true,"","","CNPJ inválido"));
return results;
}
return results;
}
private function verifyDigits(cnpj:String):Boolean {
var firstDigit:int=defineDigitValue(getDigitsPlusOperation(cnpj,FIRST_VERIFIER_DIGITS)%11);
if(new Number(firstDigit)!=new Number(cnpj.charAt(12))) {
return false;
}
var secondDigit:int=defineDigitValue((getDigitsPlusOperation(cnpj,SECOND_VERIFIER_DIGITS)+firstDigit*2)%11);
return new Number(secondDigit)==new Number(cnpj.charAt(13));
}
private function defineDigitValue(digit:int):int {
return digit>1?11-digit:0;
}
private function getDigitsPlusOperation(cnpj:String,verifierDigitis:Array):int {
var s:int=0;
for(var i:int=0;i<12;++i) {
s+=new Number(cnpj.charAt(i))*verifierDigitis[i];
}
return s;
}
}
}
Teste do CNPJ:
package br.com.nuccitelli.validator {
import flexunit.framework.Assert;
import mx.validators.ValidationResult;
public class CNPJValidatorTest {
protected var cnpjValidator:CNPJValidator=new CNPJValidator();
[Test]
public function testValidCNPJ():void {
Assert.assertNull(cnpjValidator.validate("11222333000181").results);
}
[Test]
public function testUncompleteCNPJ():void {
Assert.assertEquals("O CNPJ deve conter 14 dígitos",getValidationMessage(cnpjValidator.validate("1").results[0] as ValidationResult));
Assert.assertEquals("O CNPJ deve conter 14 dígitos",getValidationMessage(cnpjValidator.validate("1212").results[0] as ValidationResult));
Assert.assertEquals("O CNPJ deve conter 14 dígitos",getValidationMessage(cnpjValidator.validate("1122233300018").results[0] as ValidationResult));
}
[Test]
public function testWrongFinalDigits():void {
Assert.assertEquals("CNPJ inválido",getValidationMessage(cnpjValidator.validate("11222333000180").results[0] as ValidationResult));
Assert.assertEquals("CNPJ inválido",getValidationMessage(cnpjValidator.validate("11222333000191").results[0] as ValidationResult));
Assert.assertEquals("CNPJ inválido",getValidationMessage(cnpjValidator.validate("11222333000190").results[0] as ValidationResult));
}
private function getValidationMessage(result:ValidationResult):String {
return result.errorMessage;
}
}
}
CPF:
package br.com.nuccitelli.validator {
import mx.utils.ObjectUtil;
import mx.validators.ValidationResult;
import mx.validators.Validator;
public class CPFValidator extends Validator {
override protected function doValidation(value:Object):Array {
var results:Array=[];
// Call base class doValidation().
results=super.doValidation(value);
// Return if there are errors.
if(results.length>0)
return results;
// Check first name field.
var cpf:String=value as String;
if(cpf==null||cpf=="") {
return results;
} else if(cpf.length!=11) {
results.push(new ValidationResult(true,"","","O CPF deve conter 11 dígitos"));
return results;
} else if(!verifyDigits(cpf)) {
results.push(new ValidationResult(true,"","","CPF inválido"));
return results;
}
return results;
}
private function verifyDigits(cpf:String):Boolean {
var firstDigit:int=defineDigitValue(getDigitsPlusOperation(cpf,10)%11);
if(new Number(firstDigit)!=new Number(cpf.charAt(9))) {
return false;
}
var secondDigit:int=defineDigitValue((getDigitsPlusOperation(cpf,11)+firstDigit*2)%11);
return new Number(secondDigit)==new Number(cpf.charAt(10));
}
private function defineDigitValue(digit:int):int {
return digit>1?11-digit:0;
}
private function getDigitsPlusOperation(cpf:String,initialFactor:int):int {
var s:int=0;
for(var i:int=0;i<9;++i,--initialFactor) {
s+=new Number(cpf.charAt(i))*initialFactor;
}
return s;
}
}
}
Teste do CPF:
package br.com.nuccitelli.validator {
import flexunit.framework.Assert;
import mx.validators.ValidationResult;
public class CPFValidatorTest {
protected var cpfValidator:CPFValidator=new CPFValidator();
[Test]
public function testValidCPF():void {
Assert.assertNull(cpfValidator.validate("12345678909").results);
}
[Test]
public function testUncompleteCPF():void {
Assert.assertEquals("O CPF deve conter 11 dígitos",getValidationMessage(cpfValidator.validate("1").results[0] as ValidationResult));
Assert.assertEquals("O CPF deve conter 11 dígitos",getValidationMessage(cpfValidator.validate("1212").results[0] as ValidationResult));
Assert.assertEquals("O CPF deve conter 11 dígitos",getValidationMessage(cpfValidator.validate("1234567890").results[0] as ValidationResult));
}
[Test]
public function testWrongFinalDigits():void {
Assert.assertEquals("CPF inválido",getValidationMessage(cpfValidator.validate("12345678919").results[0] as ValidationResult));
Assert.assertEquals("CPF inválido",getValidationMessage(cpfValidator.validate("12345678908").results[0] as ValidationResult));
Assert.assertEquals("CPF inválido",getValidationMessage(cpfValidator.validate("12345678918").results[0] as ValidationResult));
}
private function getValidationMessage(result:ValidationResult):String {
return result.errorMessage;
}
}
}
Espero que economize tempo do pessoal :)
