Körningsmiljöversioner:

Flash Player 9, AIR 1.1

The EmailValidator class validates that a String has a single @ sign, a period in the domain name and that the top-level domain suffix has two, three, four, or six characters. IP domain names are valid if they are enclosed in square brackets. The validator does not check whether the domain and user name actually exist.

You can use IP domain names if they are enclosed in square brackets; for example, myname@[206.132.22.1]. You can use individual IP numbers from 0 to 255.

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

  <mx:EmailValidator 
    invalidCharError="Your e-mail address contains invalid characters."
    invalidDomainError= "The domain in your e-mail address is incorrectly formatted." 
    invalidIPDomainError="The IP domain in your e-mail address is incorrectly formatted." 
    invalidPeriodsInDomainError="The domain in your e-mail address has consecutive periods." 
    missingAtSignError="An at sign (&64;) is missing in your e-mail address."
    missingPeriodInDomainError="The domain in your e-mail address is missing a period." 
    missingUsernameError="The username in your e-mail address is missing." 
    tooManyAtSignsError="Your e-mail address contains too many &64; characters."

Constructor.

Metoddetaljer

doValidation

()

metod

override protected function doValidation(value:Object):Array

Språkversion:

ActionScript 3.0

Produktversion:

Flex 3

Körningsmiljöversioner:

Flash Player 9, AIR 1.1

Override of the base class doValidation() method to validate an e-mail address.

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.

Parametrar

value:Object — Either a String or an Object to validate.

Returnerar

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

validateEmail

()

metod

public static function validateEmail(validator:EmailValidator, value:Object, baseField:String):Array

Språkversion:

ActionScript 3.0

Produktversion:

Flex 3

Körningsmiljöversioner:

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.

Parametrar

	`validator:EmailValidator` — The EmailValidator 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.email, the `baseField` value is "email".

Returnerar

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