The DateFormatter class uses a format String to return a formatted date and time String from an input String or a Date object. You can create many variations easily, including international formats.
If an error occurs, an empty String is returned and a String describing
the error is saved to the error property. The error
property can have one of the following values:
-
"Invalid value"means a value that is not a Date object or a is not a recognized String representation of a date is passed to theformat()method. (An empty argument is allowed.) -
"Invalid format"means either theformatStringproperty is set to empty (""), or there is less than one pattern letter in theformatStringproperty.
The parseDateString() method uses the mx.formatters.DateBase class
to define the localized string information required to convert
a date that is formatted as a String into a Date object.
MXML 구문 표시
MXML 구문 숨기기You use the <mx:DateFormatter> tag
to render date and time Strings from a Date object.
The <mx:DateFormatter> tag
inherits all of the tag attributes of its superclass,
and adds the following tag attributes:
<mx:DateFormatter
formatString="Y|M|D|A|E|H|J|K|L|N|S|Q"
/>

The mask pattern.
You compose a pattern String using specific uppercase letters, for example: YYYY/MM.
The DateFormatter pattern String can contain other text in addition to pattern letters. To form a valid pattern String, you only need one pattern letter.
The following table describes the valid pattern letters:
| Pattern letter | Description |
|---|---|
| Y | Year. If the number of pattern letters is two, the year is
truncated to two digits; otherwise, it appears as four digits.
The year can be zero-padded, as the third example shows in the
following set of examples:
|
| M | Month in year. The format depends on the following criteria:
|
| D | Day in month. While a single-letter pattern string for day is valid,
you typically use a two-letter pattern string.
Examples:
|
| E | Day in week. The format depends on the following criteria:
|
| A | am/pm indicator. |
| J | Hour in day (0-23). |
| H | Hour in day (1-24). |
| K | Hour in am/pm (0-11). |
| L | Hour in am/pm (1-12). |
| N | Minute in hour.
Examples:
|
| S | Second in minute.
Example:
|
| Q | Millisecond in second
Example:
|
| Other text | You can add other text into the pattern string to further
format the string. You can use punctuation, numbers,
and all lowercase letters. You should avoid uppercase letters
because they may be interpreted as pattern letters.
Example:
|
기본값: "MM/DD/YYYY".

Generates a date-formatted String from either a date-formatted String or a Date object.
The formatString property
determines the format of the output String.
If value cannot be formatted, return an empty String
and write a description of the error to the error property.
매개 변수
value:Object — Date to format. This can be a Date object,
or a date-formatted String such as "Thursday, April 22, 2004".
|
String — Formatted String. Empty if an error occurs. A description
of the error condition is written to the error property.

Converts a date that is formatted as a String into a Date object. Month and day names must match the names in mx.formatters.DateBase. The hour value in the String must be between 0 and 23, inclusive. The minutes and seconds value must be between 0 and 59, inclusive. The following example uses this method to create a Date object:
var myDate:Date = DateFormatter.parseDateString("2009-12-02 23:45:30");
매개 변수
str:String — Date that is formatted as a String.
|
Date — Date object.
