Flex 4.5(으)로 시작하는 경우 이 클래스 대신 spark.validators.NumberValidator 클래스를 사용하는 것이 좋습니다. |
The NumberValidator class ensures that a String represents a valid number. It can ensure that the input falls within a given range (specified by
minValue
and maxValue
),
is an integer (specified by domain
),
is non-negative (specified by allowNegative
),
and does not exceed the specified precision
.
The validator correctly validates formatted numbers (e.g., "12,345.67")
and you can customize the thousandsSeparator
and
decimalSeparator
properties for internationalization.
MXML 구문MXML 구문 숨기기The <mx:NumberValidator>
tag
inherits all of the tag attributes of its superclass,
and adds the following tag attributes:
<mx:NumberValidator allowNegative="true|false" decimalPointCountError="The decimal separator can only occur once." decimalSeparator="." domain="real|int" exceedsMaxError="The number entered is too large." integerError="The number must be an integer." invalidCharError="The input contains invalid characters." invalidFormatCharsError="One of the formatting parameters is invalid." lowerThanMinError="The amount entered is too small." maxValue="NaN" minValue="NaN" negativeError="The amount may not be negative." precision="-1" precisionError="The amount entered has too many digits beyond the decimal point." separationError="The thousands separator must be followed by three digits." thousandsSeparator="," />

제품 버전: | Flex 3 |
런타임 버전: | Flash Player 9, AIR 1.1 |
Override of the base class doValidation()
method
to validate a number.
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 — Object to validate.
|
Array — An Array of ValidationResult objects, with one ValidationResult
object for each field examined by the validator.
|
validateNumber | () | 메서드 |
public static function validateNumber(validator:NumberValidator, value:Object, baseField:String):Array

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:NumberValidator — The NumberValidator 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.number,
the baseField value is "number".
|
Array — An Array of ValidationResult objects, with one ValidationResult
object for each field examined by the validator.
