Language Version: ActionScript 3.0
Product Version: Flex 3
Runtime Versions: Flash Player 9, AIR 1.1

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.

MXML SyntaxexpandedHide MXML Syntax

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."
  />

Implementation
    public function get invalidCharError():String
    public function set invalidCharError(value:String):void

minDigits

property 
minDigits:Object

Constructor Detail

PhoneNumberValidator

()Constructor
public function PhoneNumberValidator()

Language Version: ActionScript 3.0
Product Version: Flex 3
Runtime Versions: Flash Player 9, AIR 1.1

Constructor.

Method Detail

doValidation

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

Language Version: ActionScript 3.0
Product Version: Flex 3
Runtime Versions: Flash Player 9, AIR 1.1

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

Language Version: ActionScript 3.0
Product Version: Flex 3
Runtime Versions: Flash Player 9, AIR 1.1

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.
