View Full Version : Help with countdown timer

09-15-2011, 06:59 AM

I am wondering if someone can help me figure out a way to make the script below just countdown to midnight in my current timezone. Right now, I have to change the script at midnight manually, and that really sucks! Your answers are kindly appreciated in advance! :thumbsup:

/////CUSTOM FORMAT OUTPUT FUNCTIONS BELOW//////////////////////////////

//Create your own custom format function to pass into cdLocalTime.displaycountdown()
//Use arguments[0] to access "Days" left
//Use arguments[1] to access "Hours" left
//Use arguments[2] to access "Minutes" left
//Use arguments[3] to access "Seconds" left

//The values of these arguments may change depending on the "baseunit" parameter of cdLocalTime.displaycountdown()
//For example, if "baseunit" is set to "hours", arguments[0] becomes meaningless and contains "n/a"
//For example, if "baseunit" is set to "minutes", arguments[0] and arguments[1] become meaningless etc

//1) Display countdown using plain text
function formatresults(){
if (this.timesup==false){//if target date/time not yet met
var displaystring="<span style='background-color: #CFEAFE'>"+arguments[1]+" hours "+arguments[2]+" minutes "+arguments[3]+" seconds</span> left until launch time"
else{ //else if target date/time met
var displaystring="Launch time!"
return displaystring

//2) Display countdown with a stylish LCD look, and display an alert on target date/time
function formatresults2(){
if (this.timesup==false){ //if target date/time not yet met
var displaystring="<span class='lcdstyle'>"+arguments[1]+":"+arguments[2]+":"+arguments[3]+"</span>"
else{ //else if target date/time met
var displaystring="" //Don't display any text
alert("Launch time!") //Instead, perform a custom alert
return displaystring

You could take advantage of a wheel already invented.

<script type="text/javascript">
now = new Date();
var str = (now.getMonth()+1)+'/'+(now.getDate()+1)+'/'+now.getFullYear();

TargetDate = str+' 12:00 AM';
// TargetDate = "9/16/2011 12:00 AM";

BackColor = "palegreen";
ForeColor = "navy";
CountActive = true;
CountStepper = -1;
LeadingZero = true;

// DisplayFormat = "%%D%% Days, %%H%% Hours, %%M%% Minutes, %%S%% Seconds.";
// DisplayFormat = "%%H%% Hours, %%M%% Minutes, %%S%% Seconds.";
DisplayFormat = "%%H%%:%%M%%:%%S%%";

FinishMessage = "It is finally here!";
