Classpublic class PhoneNumberValidator
InheritancePhoneNumberValidator Inheritance Validator Inheritance EventDispatcher Inheritance Object

The PhoneNumberValidator class validates that a string is a valid phone number. A valid phone number contains at least 10 digits, plus additional formatting characters. The validator does not check if the phone number is an actual active phone number.

The <mx:PhoneNumberValidator> tag inherits all of the tag attributes of its superclass, and adds the following tag attributes:

  <mx:PhoneNumberValidator 
    allowedFormatChars="()- .+" 
    invalidCharError="Your telephone number contains invalid characters."
 	  minDigits="10"
    wrongLengthError="Your telephone number must contain at least 10 digits."

public function PhoneNumberValidator()

Constructor.

Method Detail
doValidation()method
override protected function doValidation(value:Object):Array

Override of the base class doValidation() method to validate a phone number.

You do not typically call this method directly; Flex calls it as part of performing a validation. If you create a custom Validator class, you must implement this method.

Parameters

value:Object — Object to validate.

Returns
Array — An Array of ValidationResult objects, with one ValidationResult object for each field examined by the validator.
validatePhoneNumber()method 
public static function validatePhoneNumber(validator:PhoneNumberValidator, value:Object, baseField:String):Array

Convenience method for calling a validator from within a custom validation function. Each of the standard Flex validators has a similar convenience method.

Parameters

validator:PhoneNumberValidator — The PhoneNumberValidator instance.
 
value:Object — A field to validate.
 
baseField:String — Text representation of the subfield specified in the value parameter. For example, if the value parameter specifies value.phone, the baseField value is "phone".

Returns
Array — An Array of ValidationResult objects, with one ValidationResult object for each field examined by the validator.
