countdown until

[doobster]

Hello I was wondering if someone could help me out.

I am in need of a script that will countdown to a day that is specified in the script.

I would like it to be dynamic and update every second

dd:hh:mm:ss

Then when it reaches 0 I would like the clock to disappear and my message appears.

Any help would be appreciated.

Go to http://javascript.internet.com/clocks/digital-countdown.html
and get the countdown script from there.
Then find the line newtime = window.setTimeout("getTime();", 1000);

Just after that put
if(now==later{
show();
newtime.clearTimeout()}

Then, just before the HTML comments that make up the script tags, put the script to make it appear and disappear. I would write it for you, but I'm kind of busy, and I know that there are many people who aren't busy on this forum. If you haven't been helped when I come back on, I'll do it for you.

//////////CONFIGURE THE COUNTDOWN SCRIPT HERE//////////////////

//STEP 1: Configure the countdown-to date, in the format year, month, day:
setcountdown(2003,12,20)

//STEP 2: Change the two text below to reflect the occasion, and message to display on that occasion, respectively
var occasion="the occassion......"
var message_on_occasion="Hip hip hurray!"

//STEP 3: Configure the below 5 variables to set the width, height, background color, and text style of the countdown area
var countdownwidth='750px'
var countdownheight='20px'

You might find this one a little bit easier to use.

<script type="text/javascript">
<!--
Date.ONE_SECOND = 1000;
Date.ONE_MINUTE = Date.ONE_SECOND * 60;
Date.ONE_HOUR = Date.ONE_MINUTE * 60;
Date.ONE_DAY = Date.ONE_HOUR * 24;
Date.ONE_WEEK = Date.ONE_DAY * 7;

function TimeUntil (d) {this.time = d.getTime ? d.getTime() : Date.parse(d)}

TimeUntil.prototype.valueOf = function () {return this.time - new Date ().getTime()}

TimeUntil.prototype.toString = function () {
var t = Math.abs(this.valueOf());
var d = Math.floor (t / Date.ONE_DAY);
var h = Math.floor ((t % Date.ONE_DAY) / Date.ONE_HOUR);
var m = Math.floor ((t % Date.ONE_HOUR) / Date.ONE_MINUTE);
var s = Math.floor ((t % Date.ONE_MINUTE) / Date.ONE_SECOND);
return (this.valueOf () < 0 ? '-' : '') + [d, d == 1 ? 'day' : 'days', [h, m < 10 ? '0' + m : m, s < 10 ? '0' + s : s].join(':')].join(' ');
}

// The above part of the script can go in the document HEAD if you prefer

var time = new TimeUntil ('1 August 2003 10:00 CDT');

document.write('<p>Time until the 2003 <a href="http://hooverassoc.org/hooverball.htm">Hooverball</a> National Championships: <span id="time">',time , '</span></p>');

if (document.getElementById) setInterval ("document.getElementById('time').replaceChild(document.createTextNode (time), document.getElementById('time').firstChild)",0.2 * Date.ONE_SECOND);

// -->
</script>

Thanks everyone. I really like the last one posted by Charles. But I am wondering if someone could help me alter so when it reaches 0 I could display a new message.

[Charles]

if (document.getElementById) setInterval ("document.getElementById('time').replaceChild(document.createTextNode (time > 0 ? time : 'It\\\'s already started if it hasn\\\'t already ended.'), document.getElementById('time').firstChild)",0.2 * Date.ONE_SECOND);

or

document.write('<p id="time">Time left: ',time , '</p>');

if (document.getElementById) var interval = setInterval ("document.getElementById('time').replaceChild(document.createTextNode ('Time left: ' + time.toString()), document.getElementById('time').firstChild); if (time <= 0) {clearInterval(interval); document.getElementById('time').replaceChild(document.createTextNode ('The time has come.'), document.getElementById('time').firstChild)}",0.2 * Date.ONE_SECOND);

[Charles]

Here's a better way to do that:

<script type="text/javascript">
<!--
Date.ONE_SECOND = 1000;
Date.ONE_MINUTE = Date.ONE_SECOND * 60;
Date.ONE_HOUR = Date.ONE_MINUTE * 60;
Date.ONE_DAY = Date.ONE_HOUR * 24;
Date.ONE_WEEK = Date.ONE_DAY * 7;

function TimeUntil (d) {this.time = d.getTime ? d.getTime() : Date.parse(d)}

TimeUntil.prototype.valueOf = function () {return this.time - new Date ().getTime()}

TimeUntil.prototype.toString = function () {
var t = Math.abs(this.valueOf());
var d = Math.floor (t / Date.ONE_DAY);
var h = Math.floor ((t % Date.ONE_DAY) / Date.ONE_HOUR);
var m = Math.floor ((t % Date.ONE_HOUR) / Date.ONE_MINUTE);
var s = Math.floor ((t % Date.ONE_MINUTE) / Date.ONE_SECOND);
return (this.valueOf () < 0 ? '-' : '') + [d, d == 1 ? 'day' : 'days', [h, m < 10 ? '0' + m : m, s < 10 ? '0' + s : s].join(':')].join(' ');
}

// The above part of the script can go in the document HEAD if you prefer

var time = new TimeUntil ('1 August 2003 10:00 CDT');
time.toMyString = function () {return this.valueOf() > 0 ? 'Time left: ' + this.toString() : 'The time has come.'}

document.write('<p id="time">',time.toMyString() , '</p>');

if (document.getElementById) var int = setInterval ("document.getElementById('time').replaceChild(document.createTextNode (time.toMyString()), document.getElementById('time').firstChild); if (time <= 0) clearInterval(int)",0.2 * Date.ONE_SECOND);

// -->
</script>

I am trying to add some more lines text and html code but am having weird problems.


time.toMyString = function () {return this.valueOf() > 0 ? 'Time left: ' + this.toString() + '<img src=something.jpg' : 'The time has come.'}


When I add some html code after the this.toString it displays the html code as plain text and it also displays the html code properly.

I cannot figure out why.

[Charles]

document.getElementById('time').replaceChild(document.createTextNode (time.toMyString()), document.getElementById('time').firstChild)

You're going to need to play with the DOM.

[Charles]

Perhaps something like:

var time = new TimeUntil ('1 August 2003 10:00 CDT');

time.toRunningNode = function () {
var link = document.createElement('a');
link.setAttribute('href', 'http://hooverassoc.org/hooverball.htm');
link.appendChild(document.createTextNode('HooverBall'));

var running = document.createElement('p');
running.appendChild(document.createTextNode('Time until '));
running.appendChild(link);
running.appendChild(document.createTextNode(' National Championships: ' + this.toString()));
return running;
}

time.toDoneNode = function () {
var done = document.createElement('p');
done.appendChild(document.createTextNode('The time has come.'));
return done;
}

if (document.getElementById) {

document.write('<div id="time">&nbsp;</div>');
var timeNode = document.getElementById('time');

var interval = setInterval("if (time > 0) {timeNode.replaceChild(time.toRunningNode(), timeNode.firstChild)} else {clearInterval(interval); timeNode.replaceChild(time.toDoneNode(), timeNode.firstChild)}", Date.ONE_SECOND);

}
