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.

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.
