int
,uint
, and Number
objects.
This class uses the locale
style for specifying the
requested locale ID.
The validator can ensure that the input falls within a given range
(specified by minValue
and maxValue
properties),
is an integer (specified by domain
property),
is non-negative (specified by allowNegative
property),
correctly specifies negative and positive numbers,
and does not exceed the specified number offractionalDigits
.
The validator sets default property values by making use of the
flash.globalization.NumberFormatter
and therefore the locale
specific values are supplied by the operating system.
The NumberValidator
class can be used in MXML declarations
or in ActionScript code. This class uses the locale style for specifying the
requested Locale ID required by the
flash.globalization.NumberFormatter
class, and has methods and
properties that are bindable.
The <spark:NumberValidator>
tag
inherits all of the tag attributes of its superclass,
and adds the following tag attributes:
<s:NumberValidator Properties negativeNumberFormat="locale specified string or customized by user." negativeNumberFormatError="The negative format of the input number is incorrect." />

Çalışma Zamanı Sürümleri: | Flash Player 10.1, AIR 2.5 |
A numeric value that indicates a validating pattern for negative numbers. This pattern defines the location of the negative symbol or parentheses in relation to the numeric portion of the number to be validated.
The following table summarizes the possible formats for
negative numbers. When a negative number is validated,
the minus sign represents the value of
the negativeSymbol
property and the 'n' character
represents numeric value.
Negative number format type | Format |
0 | (n) |
1 | -n |

Constructs a new NumberValidator object to validate numbers according to the conventions of a given locale.
The locale for this class is supplied by the locale
style.
The locale
style can be set in several ways:
-
Inheriting the style from a
UIComponent
by calling theUIComponent
'saddStyleClient
method. -
By using the class in an MXML declaration and inheriting the
locale from the document that contains the declaration.
<fx:Declarations> <s:NumberValidator id="nv" /> </fx:Declarations>
-
By using an MXML declaration and specifying the locale value in
the list of assignments.
<fx:Declarations> <s:NumberValidator id="nv_French_France" locale="fr_FR" /> </fx:Declarations>
-
Calling the
setStyle
method. For example:nv.setStyle("locale", "fr-FR")
If the locale
style is not set by one of the above
techniques, the instance of this class will be added as a
StyleClient
to the topLevelApplication
and
will therefore inherit the locale
style from the
topLevelApplication
object when the locale
dependent property getter or locale
dependent method is
called.

convenience method. Caller must check the ValidationResult
objects in the returned array for validation status.
Parametreler
value:Object — A number string to validate.
| |
baseField:String — Text representation of the subfield specified in the
value object.
For example, if the value parameter specifies value.number,
the baseField value is "number".
