實作
protected function get resourceManager():IResourceManager

source

屬性

source:Object

語言版本:

ActionScript 3.0

產品版本:

Flex 4.5

執行階段版本:

Flash Player 10.1, AIR 2.5

Specifies the object containing the property to validate. Set this to an instance of a component or a data model. You use data binding syntax in MXML to specify the value. This property supports dot-delimited Strings for specifying nested properties. If you specify a value to the source property, then you should specify a value to the property property as well. The source property is optional.

預設值為 null。

Flash Player 10.1, AIR 2.5

An Array of Strings containing the names for the properties contained in the value Object passed to the validate() method. For example, CreditCardValidator sets this property to [ "cardNumber", "cardType" ]. This value means that the value Object passed to the validate() method should contain a cardNumber and a cardType property.

trigger

屬性

trigger:IEventDispatcher

語言版本:

ActionScript 3.0

產品版本:

Flex 4.5

執行階段版本:

Flash Player 10.1, AIR 2.5

Specifies the component generating the event that triggers the validator. If omitted, by default Flex uses the value of the source property. When the trigger dispatches a triggerEvent, validation executes.

實作
public function get trigger():IEventDispatcher
public function set trigger(value:IEventDispatcher):void

triggerEvent

屬性

triggerEvent:String

語言版本:

ActionScript 3.0

產品版本:

Flex 4.5

執行階段版本:

Flash Player 10.1, AIR 2.5

Specifies the event that triggers the validation. If omitted, Flex uses the valueCommit event. Flex dispatches the valueCommit event when a user completes data entry into a control. Usually this is when the user removes focus from the component, or when a property value is changed programmatically. If you want a validator to ignore all events, set triggerEvent to the empty string ("").

實作
public function get triggerEvent():String
public function set triggerEvent(value:String):void

Constructor.

方法詳細資訊

addListenerHandler

()

方法

protected function addListenerHandler():void

語言版本:

ActionScript 3.0

產品版本:

Flex 4.5

執行階段版本:

Flash Player 10.1, AIR 2.5

Sets up all of the listeners for the valid and invalid events dispatched from the validator. Subclasses of the GlobalizationValidatorBase class should first call the removeListenerHandler() method, and then the addListenerHandler() method if the value of one of their listeners or sources changes. The CreditCardValidator and DateValidator classes use this function internally.

doValidation

()

方法

protected function doValidation(value:Object):Array

語言版本:

ActionScript 3.0

產品版本:

Flex 4.5

執行階段版本:

Flash Player 10.1, AIR 2.5

Executes the validation logic of this validator, including validating that a missing or empty value causes a validation error as defined by the value of the required property.

If you create a subclass of a validator class, you must override this method.

參數

value:Object — Value to validate.

傳回值

Array — For an invalid result, an Array of ValidationResult objects, with one ValidationResult object for each field examined by the validator that failed validation.

相關 API 元素

getValueFromSource

()

方法

protected function getValueFromSource():Object

語言版本:

ActionScript 3.0

產品版本:

Flex 4.5

執行階段版本:

Flash Player 10.1, AIR 2.5

Returns the Object to validate.

傳回值

Object — The Object to validate.

handleResults

()

方法

protected function handleResults(errorResults:Array):ValidationResultEvent

語言版本:

ActionScript 3.0

產品版本:

Flex 4.5

執行階段版本:

Flash Player 10.1, AIR 2.5

Returns a ValidationResultEvent from the Array of error results. Internally, this function takes the results from the doValidation() method and puts it into a ValidationResultEvent object. You never call this function directly, and you should rarely override it.

參數

errorResults:Array — Array of ValidationResult objects.

傳回值

ValidationResultEvent — The ValidationResultEvent returned by the validate() method.

isRealValue

()

方法

protected function isRealValue(value:Object):Boolean

語言版本:

ActionScript 3.0

產品版本:

Flex 4.5

執行階段版本:

Flash Player 10.1, AIR 2.5

Returns true if value is not null.

參數

value:Object — The value to test.

傳回值

Boolean — true if value is not null.

removeListenerHandler

()

方法

protected function removeListenerHandler():void

語言版本:

ActionScript 3.0

產品版本:

Flex 4.5

執行階段版本:

Flash Player 10.1, AIR 2.5

Disconnects all of the listeners for the valid and invalid events dispatched from the validator. Subclasses should first call the removeListenerHandler() method and then the addListenerHandler method if the value of one of their listeners or sources changes. The CreditCardValidator and DateValidator classes use this function internally.

resourcesChanged

()

方法

protected function resourcesChanged():void

語言版本:

ActionScript 3.0

產品版本:

Flex 4.5

執行階段版本:

Flash Player 10.1, AIR 2.5

This method is called when a GlobalizationValidatorBase is constructed, and again whenever the ResourceManager dispatches a "change" Event to indicate that the localized resources have changed in some way.

This event will be dispatched when you set the ResourceManager's localeChain property, when a resource module has finished loading, and when you call the ResourceManager's update() method.

Subclasses should override this method and, after calling super.resourcesChanged(), do whatever is appropriate in response to having new resource values.

validate

()

方法

public function validate(value:Object = null, suppressEvents:Boolean = false):ValidationResultEvent

語言版本:

ActionScript 3.0

產品版本:

Flex 4.5

執行階段版本:

Flash Player 10.1, AIR 2.5

Performs validation and optionally notifies the listeners of the result.

參數

	`value:Object` (default = `null`) — Optional value to validate. If null, then the validator uses the `source` and `property` properties to determine the value. If you specify this argument, you should also set the `listener` property to specify the target component for any validation error messages.

	`suppressEvents:Boolean` (default = `false`) — If `false`, then after validation, the validator will notify the listener of the result.

傳回值

ValidationResultEvent — A ValidationResultEvent object containing the results of the validation. For a successful validation, the ValidationResultEvent.results Array property is empty. For a validation failure, the ValidationResultEvent.results Array property contains one ValidationResult object for each field checked by the validator, both for fields that failed the validation and for fields that passed. Examine the ValidationResult.isError property to determine if the field passed or failed the validation.

validateAll

()

方法

public static function validateAll(validators:Array):Array

語言版本:

ActionScript 3.0

產品版本:

Flex 4.5

執行階段版本:

Flash Player 10.1, AIR 2.5

Invokes all the validators in the validators Array. Returns an Array containing one ValidationResultEvent object for each validator that failed. Returns an empty Array if all validators succeed.

參數

validators:Array — An Array containing the GlobalizationValidatorBase objects to execute.

傳回值

Array — Array of ValidationResultEvent objects, where the Array contains one ValidationResultEvent object for each validator that failed. The Array is empty if all validators succeed.
