The ZipCodeValidator class validates that a String has the correct length and format for a five-digit ZIP code, a five-digit+four-digit United States ZIP code, or Canadian postal code.

MXML SyntaxexpandedHide MXML Syntax

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

  <mx:ZipCodeValidator
    allowedFormatChars=" -" 
    domain="US Only | US or Canada | Canada Only"
    invalidCharError="The ZIP code contains invalid characters." 
    invalidDomainError="The domain parameter is invalid. It must be either 'US Only', 'Canada Only', or 'US or Canada'." 
    wrongCAFormatError="The Canadian postal code must be formatted 'A1B 2C3'." 
    wrongLengthError="The ZIP code must be 5 digits or 5+4 digits." 
    wrongUSFormatError="The ZIP+4 code must be formatted '12345-6789'."

Constructor Detail

ZipCodeValidator

()Constructor
public function ZipCodeValidator()

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 ZIP code.

You do not 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.

validateZipCode

()method 
public static function validateZipCode(validator:ZipCodeValidator, 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. Each of the standard Flex validators has a similar convenience method.

Parameters

validator:ZipCodeValidator — The ZipCodeValidator 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.zipCode, the baseField value is "zipCode".

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