- The month is between 1 and 12 (or 0-11 for
Dateobjects) - The day is between 1 and 31
- The year is a number
You can specify the date in the DateValidator class in two ways:
- Single String containing the date - Use the
sourceandpropertyproperties to specify the String. The String can contain digits and the formatting characters specified by theallowedFormatCharsproperty, which include the "/\-. " characters. By default, the input format of the date in a String field is "MM/DD/YYYY" where "MM" is the month, "DD" is the day, and "YYYY" is the year. You can use theinputFormatproperty to specify a different format. -
Dateobject. - Object or multiple fields containing the day, month, and year.
Use all of the following properties to specify the day, month,
and year inputs:
daySource,dayProperty,monthSource,monthProperty,yearSource, andyearProperty.

override protected function doValidation(value:Object):Array| 언어 버전: | ActionScript 3.0 |
| 제품 버전: | Flex 3 |
| 런타임 버전: | Flash Player 9, AIR 1.1 |
Override of the base class doValidation() method
to validate a date.
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.
매개 변수
value:Object — Either a String or an Object to validate.
|
Array — An Array of ValidationResult objects, with one ValidationResult
object for each field examined by the validator.
|
validateDate | () | 메서드 |
public static function validateDate(validator:DateValidator, value:Object, baseField:String):Array| 언어 버전: | ActionScript 3.0 |
| 제품 버전: | Flex 3 |
| 런타임 버전: | 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.
매개 변수
validator:DateValidator — The DateValidator 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.date, the baseField value is "date".
|
Array — An Array of ValidationResult objects, with one ValidationResult
object for each field examined by the validator.
