Flex 4 - How to convert string(yyyy/mm/dd) to date object?

Question

I am taking date input from DateField in flex. And I have an XML file with date in YYYY/MM/DD format i.e string format. How to convert this string to Date object? And I have to compare these two values?

I am getting "Tue Feb 4 00:00:00 GMT-0800 2014" this type of output from the DateField selection. And I have to use "dateCompare()" function(It's like restriction).

Answer 1

Date.parse function should work with that format , if is not working you can use the Array.split to get the values you need,

var d:Date=new Date();
var matches:Array=string.split("/");
d.setUTCFullYear(int(matches[0]), int(matches[1]) - 1, int(matches[2]))

To Set the time you can use the method setUTCHours

see documentation

d.setUTCHours(0,0,0,0)

EDIT:

var string:String="2008/11/13";
            var d:Date=new Date();
            var matches:Array=string.split("/");
            d.setUTCFullYear(int(matches[0]), int(matches[1]) - 1, int(matches[2]))
            trace(d);
             d.setUTCHours(12,11,13);
            trace(d); 

Answer 2

The simpler way is to use the parseDateStrig static method from mx.formatters.DateFormatter

var date:Date = DateFormatter.parseDateString("2013/1/11", "YYYY/MM/DD");

Answer 3

This is a function I use to do something similar. You can adapt it to fit your needs.

public static function convertSQLDate( dateString : String ) : Date
{
    if( dateString == null ) return null;

    var datePattern : RegExp = /(\d{4})-(\d+)-(\d+)( (\d+):(\d+):(\d+))?/;
    var result : Object = datePattern.exec( dateString );

    if( result[ 4 ] != null ) return new Date( result[1], result[2] - 1, result[3], result[ 5 ], result[ 6 ], result[ 7 ] );
    else return new Date( result[1], result[2] - 1, result[3] );            

}

Use DateTimeFormatter... for specific format....then check with your xml data.

s:DateTimeFormatter id="datePattern" dateTimePattern="yyyy/MM/dd"

if(datePattern.format(dateChooser.selectedDate) == "2014/03/01")

lblCheck.text = "Check...";

else

lblCheck.text = "Not Check..";

Use below link for DateTimeFormatter...
