Date object.
This class is a wrapper class around the flash.globalization.DateTimeFormatter class. Therefore, the locale-specific formatting functionality and the month names, day names and the first day of the week are provided by the flash.globalization.DateTimeFormatter. However, this DateTimeFormatter class can be used in MXML declarations, uses the locale style for the requested Locale ID name, and has methods and properties that are bindable.
The flash.globalization.DateTimeFormatter class uses the underlying operating system for the formatting functionality and to supply the locale-specific data. On some operating systems, the flash.globalization classes are unsupported, on these systems, this wrapper class provides fallback functionality.

The name of the actual locale ID used by this class object. This is the locale that is used to access the formatting data and functionality from the operating system.
If the locale that was set by the locale style is not available,
then the value of the actualLocaleIDName is different

dateStyle | 屬性 |
dateStyle: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 |
The date style for this instance of the DateTimeFormatter.
The date style is used to retrieve a predefined time and locale
specific formatting pattern from the operating system.
When formatting a date, the locale style, the
timeStyle and the dateStyle properties
determine the format of the date.
The date style value can be set in the following two ways:
assigning a value to either the dateStyle property or
the dateTimePattern property.
The possible for this property are defined by
the flash.globalization.DateTimeStyle class.
Possible values for the dateStyle property are:
DateTimeStyle.LONGDateTimeStyle.MEDIUMDateTimeStyle.SHORTDateTimeStyle.NONEDateTimeStyle.CUSTOM
If the dateTimePattern
property is assigned a value, as a side effect, the dateStyle property
is set to DateTimeStyle.CUSTOM
預設值為 DateTimeStyle.LONG。
此屬性可以做為資料繫結的來源。一旦修改此屬性，將傳送 change 事件。

This pattern can be set in one of two ways:
- By setting the
dateStyleandtimeStyleproperties. - By setting the
dateTimePatternproperty.
If this property is assigned a value directly, as a side effect,
the current time and date styles are overridden and
set to the value DateTimeStyle.CUSTOM.
For a description of the pattern syntax, please see the
flash.globalization.DateTimeFormatter.setDateTimePattern()
method.
預設值為 "EEEE, MMMM dd, yyyy h:mm:ss a"。

DateTimeFormatter | () | 建構函式 |
public function DateTimeFormatter()| 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 |
Constructs a new DateTimeFormatter object to format
dates and times according to the conventions of the specified locale
and the provided date and time formatting styles.
The locale for this class is supplied by the locale style. The locale style can be set in several ways:
- By using the class in an MXML declaration and inheriting the locale from the document that contains the declaration. Example:
<fx:Declarations>
<s:DateTimeFormatter id="df" />
</fx:Declarations>
<fx:Declarations>
<s:DateTimeFormatter id="df_Japanese" locale="ja-JP" />
</fx:Declarations>
df.setStyle("locale", "ja-JP")
UIComponent by calling the
UIComponent's addStyleClient() method.
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.
Most of the properties of this class are automatically set based on the locale style. If the locale style is changed, any properties that have not been explicitly set will also be updated based on the new locale. Note that the actual locale that is used is specified by the actualLocaleIDName property.

format | () | 方法 |
public function format(value:Object):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 |
Formats a display string for an object that specifies a date in either the user's local time or UTC time.
A Date object has two sets of date and time values,
those in the user's local time (date, day, fullYear, hours,
minutes, month, and seconds) and those in UTC
time (dateUTC, dayUTC,
fullYearUTC, hoursUTC, minutesUTC, monthUTC, and
secondsUTC).
The boolean property useUTC controls which set of
date and time components are used when formatting the date.
The formatting will be done using the conventions of the locale as
set by the locale style property and the
dateStyle and timeStyle properties, or the
dateTimePattern, specified for this
DateTimeFormatter instance.
If there is an error when formatting, due to an illegal input value
or other error, by default the format() method will
return null. However if the errorText property
is non-null, then the value of the errorText property will
be returned. The lastOperationStatus property will be
set to indicate the error that occurred.
參數
value:Object — A Date value to be formatted. If the
object is not a Date then it will be converted
to a date using the Date() constructor.
|
String — A formatted string representing the date or time value.
