example: Countdown display including year and month information(AS2)

17 07 2008

[UPDATE] I have uploaded a screenshot of a sample source file for your reference. Please check it out. 🙂 Thanks for the comments.

Very few code examples I could find online have included the number of years and months in them. So I thought I’d come up with my own. It is currently in AS2, leave a comment if you need an AS3 version.

[+] DateUtils class. The function getCountDown takes 2 Date objects and returns a generic object which includes the number of years, months, days, hours, minutes, seconds and milliseconds of the time that is spent to get to the end Date from the start Date. See below.

class DateUtils {
	private static var NUM_MSEC_IN_SECOND:Number = 1000;
	private static var NUM_SEC_IN_MINUTE:Number = 60;
	private static var NUM_MIN_IN_HOUR:Number = 60;
	private static var NUM_HOUR_IN_DAY:Number = 24;
	private static var NUM_MON_IN_YEAR:Number = 12;
	private static var NUM_OF_UNITS:Number = 7; // year, month, day, hours, minutes, seconds, millisesconds

	public static function getCountDown(start:Date,end:Date):Object {
		//trace ("DateUtils, getCountDown of start date:" + start+", end date:"+end);
		if (start == undefined || start == null) start = new Date();
		if (end == undefined || end == null) end = new Date();

		//if the end date is no later than start date, return 0s as results.
		if (end.getTime() - start.getTime()<=0)  return {year:0,month:0,day:0,hour:0,minute:0,second:0,millisecond:0};

		//if the end date is later than start date, continue to do the calculation
		var eY:Number = end.getFullYear();
		var eMon:Number = end.getMonth();
		var start_ary:Array = &#91;start.getMilliseconds(),start.getSeconds(),start.getMinutes(),start.getHours(),start.getDate(),start.getMonth(),start.getFullYear()&#93;;
		var end_ary:Array = &#91;end.getMilliseconds(),end.getSeconds(),end.getMinutes(),end.getHours(),end.getDate(),end.getMonth(),end.getFullYear()&#93;;
		var period_ary:Array = new Array();

		for (var i:Number=0; i<NUM_OF_UNITS; i++)
		for (var i:Number=0; i<NUM_OF_UNITS; i++)
			if (period_ary&#91;i&#93;<0)
				period_ary&#91;i+1&#93; -= 1;
				if (convsRate_ary&#91;i&#93; == NaN) convsRate_ary&#91;i&#93; = (eMon>0)?getNumDaysInMonth(eY,eMon-1):getNumDaysInMonth(eY-1,eMon-1+NUM_MON_IN_YEAR);
				period_ary[i] += convsRate_ary[i];
		return {year:period_ary[6],month:period_ary[5],day:period_ary[4],hour:period_ary[3],minute:period_ary[2],second:period_ary[1],millisecond:period_ary[0]}

	public static function getNumDaysInMonth(year:Number,month:Number):Number
		if (month<0 || month>=NUM_MON_IN_YEAR) return 0;
		var firstDayInThisMonth:Date = new Date(year,month,1);
		var firstDayInNextMonth:Date = (month<NUM_MON_IN_YEAR-1) ? new Date(year,month+1,1) : new Date(year+1,month+1-NUM_MON_IN_YEAR,1);
		var numDays:Number = (firstDayInNextMonth.getTime() - firstDayInThisMonth.getTime()) / NUM_MSEC_IN_SECOND / NUM_SEC_IN_MINUTE / NUM_MIN_IN_HOUR / NUM_HOUR_IN_DAY;
		return Math.floor(numDays);

&#91;+&#93; CountDownDisplay class. It extends MovieClip and has a TextField on its timeline, with the instance name "txt". The function <em>init</em> takes a target <strong>Date</strong> object to count down (from today) to, and the frequency (in milliseconds) to update the display. The function <em>kill</em> clears the interval.

import mx.utils.Delegate;

class CountDownDisplay extends MovieClip {
	public var txt:TextField;
	private var _intvl:Number;
	private var _frqc:Number;
	private var _tDate:Date;
	private static var DIVIDING_SYMBOL:String = ":";

	private function CountDownDisplay() {}
	public function init(targetDate:Date, frequency:Number):Void
		_tDate = targetDate;
		_frqc = (frequency==0 || frequency==undefined)?100:frequency;
		//this.onEnterFrame = Delegate.create(this,update);
		_intvl = setInterval(Delegate.create(this,update),frequency);
	public function kill():Void
		if (_intvl != undefined) 		clearInterval(_intvl);
	private function update():Void
		_intvl = undefined;
		var obj:Object = DateUtils.getCountDown(new Date(),_tDate);
		var y:String = obj.year.toString();
		var mon:String = obj.month.toString();
		var d:String = obj.day.toString();
		var h:String = obj.hour.toString();
		var m:String = obj.minute.toString();
		var s:String = obj.second.toString();
		var ms:String = (Math.floor((obj.millisecond) / 10)).toString();

		y = toTwoDigit(y);
		mon = toTwoDigit(mon);
		d = toTwoDigit(d);
		h = toTwoDigit(h);
		m = toTwoDigit(m);
		s = toTwoDigit(s);
		ms = toTwoDigit(ms);

		_intvl = setInterval(Delegate.create(this,update),_frqc);

	private function toTwoDigit ( str:String ) : String
		var new_str:String = str;
		switch (true)
			case Boolean(str.length==0):
				new_str = "00";
			case Boolean(str.length==1):
				new_str = "0"+str;
			case Boolean(str.length>2):
				new_str = "**";
		return new_str;

There you go. I’d be happy to send you a .fla file as an example. Let me know please.
