Javascript countdown

So I’ve created this little countdown tool.

This will count down to a specific date and time… and then display a specific message during and then after the specified time.

It’s pretty lightweight (and relies on JQuery – again)

The Countdown HTML:

<span class="lineOne">This is where the countdown goes </span>
<span class="subLine">until the event</span>

The Countdown Javascript:

You’ll see on line 8 and 9 there are timestamps – these are for the beginning and the end of the event – you’ll have to figure out what the timestamps for these dates and times are.

Line 44 and 49 are the messages that will come up during and after the event.

$(document).ready(function(){
		console.log("ping");
		var 	countSpeed = 2,
			dayLength = 86400000,
			hourLength = 3600000,
			minLength = 60000,
			secondLength = 1000,
			eventStamp = 1396125000000,
			eventOverStamp = 1396128600000;
			setInterval(countUp,1000 / countSpeed);

		function countUp(){

			var 	thisNow = jQuery.now(),
				eventDiff = eventStamp - thisNow,
				daysLeft = eventDiff / dayLength,
				daysLeft = Math.floor(daysLeft),
				hoursLeft = (eventDiff - (daysLeft * dayLength)) / hourLength,
				hoursLeft = Math.floor(hoursLeft),
				minsLeft = (eventDiff - (daysLeft * dayLength) - (hoursLeft * hourLength)) / minLength,
				minsLeft = Math.floor(minsLeft),
				secsLeft = (eventDiff - (daysLeft * dayLength) - (hoursLeft * hourLength) - (minsLeft * minLength)) / secondLength,
				secsLeft = Math.floor(secsLeft);
				millisLeft = eventDiff - (daysLeft * dayLength) - (hoursLeft * hourLength) - (minsLeft * minLength) - (secsLeft * secondLength);
				if(millisLeft > 99) { 
					millisLeft = ""+millisLeft;
					millisLeft = millisLeft.substring(0, millisLeft.length - 1);
				}
				if(secsLeft<10){ secsLeft = "0" + secsLeft; }
				if(minsLeft<10){ minsLeft = "0" + minsLeft; }
				if(hoursLeft<10){ hoursLeft = "0" + hoursLeft; }
				if(daysLeft<10){ daysLeft = "0" + daysLeft; }

			$(".lineOne").empty().append("00 days 00 hours 00 minutes 00 seconds ");
			$("#days").empty().append(daysLeft);
			$("#hours").empty().append(hoursLeft);
			$("#minutes").empty().append(minsLeft);
			$("#seconds").empty().append(secsLeft);
			$("#millis").empty().append(millisLeft);

			if(thisNow > eventStamp && thisNow < eventOverStamp){ 				$(".lineOne").empty().append("Earth Hour"); 				$(".subLine").empty().append("is currently underway").css("margin-top", "180px"); 				$("#heroSpace .wwf_button").empty().append("Find out what's happening"); 			} 			else if (thisNow > eventOverStamp){
				$(".lineOne").empty().append("Earth Hour");
				$(".subLine").empty().append("has been and gone").css("margin-top", "180px");
				$("#heroSpace .wwf_button").empty().append("Find out what happened");
			}

		};

	})

Obviously – please feel free to use as you wish. Let me know how you’ve found it in the comments.

Count down to Earth Hour

So this week was the 60 day count down to Earth Hour and to celebrate WWF produced a list of 60 things to do in the dark.

To remind visitors about the campaign we booked in a homepage take over of the main WWF site focusing on Earth Hour and in particular the count down… which gave me an opportunity to play with some simple js and do something a little fun.

The code (if you’re interested) is below – for your enjoyment. The stats – so far – are looking good.

Homepages are funny things – and I plan to write a blog post on them soon – but in short we sometimes put a lot of focus on them and forget that visitors usually arrive at our sites for a reason… and that reason is rarely to see what random offering is being featured on the HP.

Anything we can do to draw attention toward valuable calls to action – including the occasional bit of movement – should always be considered (if only to be dismissed). But it is also important not let that get in the way of the user’s journey toward the reason for their visit. This can only lead to a ruined online relationship… so when you’re monitoring look for the impact elsewhere also (negative or positive).

Anyhow – the code:

$(document).ready(function(){
	var countMe = 0,
		countSpeed = 40;
	$(".subLine").fadeOut(0);
	$(".count").empty();
	setInterval(countUp,countSpeed);

	function countUp(){
		$(".count").empty();
		if(countMe<10){ $(".count").append("0" + countMe); }
		else { $(".count").append(countMe); }
		
		if(countMe<60){
			countMe = countMe+1;
		} else {
			$(".subLine").fadeIn(1000);
		}
	}
})
