JavaScript - Help With A Javascript Clock I Made
I am pretty new to javascript and descided to test my skills by making a javascript clock using the computers time
it works but I know the way I am doing it isn't very good you can see the code below Code: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"

<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<script type="text/javascript">
var minutes = 0;
var seconds;
var hour = 0;
var minute = new Date().getMinutes();
minutes += minute;
var hours = new Date().getHours();
hour += hours;
var time_period = "";
if(hour > 12){
hour = hour-12;
time_period = "PM";
}else {
time_period = "AM";
}
function working_clock(){
var time = new Date;
seconds = time.getSeconds();
var clock = document.getElementById('clock');
if(seconds == 59){
minutes+=1;
}
if(minutes == 60){
minutes = 1;
hour++;
}
if(minutes < 10){
var minute_digit_two = 0;
clock.innerHTML = ("time: "+hour+":"+minute_digit_two +minutes+":"+seconds+" "+time_period);
}else {
clock.innerHTML = ("time: "+hour+":"+minutes+":"+seconds+" "+time_period);
}
setTimeout("working_clock()",1000);
}
window.onload = working_clock;
</script>
</head>
<body>
<div id="clock"></div>

</html>
heres where you can see it in action http://the-test.comoj.com/files/working-clock.html im just asking if there are any errors or if theres a better way to do this Similar TutorialsJavascript for clock: Code: function showTime (dateObj) {
thissecond=dateObj.getSeconds();
thisMinute=dateObj.getMinutes();
thisHour=dateObj.getHours();
// change thisHour from 24-hour time to 12-hour time by:
// 1) if thisHour < 12 then set ampm to "a.m." otherwise set it to "p.m."
var ampm = (thisHour < 12) ? "a.m." : "p.m.";
// 2) subtract 12 from the thisHour variable
thisHour = (thisHour > 12) ? thisHour - 12 : thisHour;
// 3) if thisHour equals 0, change it to 12
thisHour = (thisHour == 0) ? 12 : thisHour;
// add leading zeros to minutes and seconds less than 10
thisMinute = thisMinute < 10 ? "0"+thisMinute : thisMinute;
thisSecond = thisSecond < 10 ? "0"+thisSecond : thisSecond;
return thisHour + ":" + thisMinute + ":" + thisSecond + ampm;

Does anyone know how to put my clock into my HTM and CSS files to have it appear at the top left of the page? Please, help. Thanks. Hello everybody. I need to make a javascript (and only javascript, no php and such) clock, that the hours and the minuets can be updated manually by an html form with 2 fields. I cant find a way to do this. thanks in advance, danbb. Hi, I'm not good with manipulating JavaScript for my needs and I am trying to use a JavaScript file to implement my common content in to my web page, in this case it is a news article I want to display across all of my web pages. The problem is that I want to style it and use html attributes in side of the document.write and that is apparently messing it up. Would someone be able to show me how to fix this problem or fix the code so I can get the common content to display correctly with styling from CSS. If possible I would like to keep the CSS in a separate file and put a link to it in the JavaScript file and use the class tags, but I do not know how far we can go with JavaScript. Thanks for helping. Here are links to the webpage where I would like the code to show up. Below is the JavaScript that is currently in my .js file. http://www.nasawear.com/Home.html (The news article should display in the right column.) Code: document.write("<link rel="stylesheet" type="text/css" href="css/mainpage.css" />");
document.write("<h3 class="section">");
document.write("New NASA News");
document.write("</h3>");

<p class="dis">
Astronomers using NASA's Hubble Space Telescope have confirmed the existence of a baked object that could be called a "cometary planet." The gas giant planet, named HD 209458b, is orbiting so close to its star that its heated atmosphere is escaping into space.
<br/>
<br/>
Observations taken with Hubble's Cosmic Origins Spectrograph (COS) suggest powerful stellar winds are sweeping the cast-off atmospheric material behind the scorched planet and shaping it into a comet-like tail.

hello all, this is my first time on this site and i can usally find all the information i need on google. However iv run into a problem while coding a countdown timer for students in my school i will be hosting it as a mobile website. what im having problems with is getting not the system time, but 1 syncronized time source ex. The official U.S.time or any other single time source if that one will not be the best. any suggestions? ps. i am completely new to js so make any suggestions and please explain throughly. Thanks! Thanks for clicking on the link and i presume while you are here on my thread yo u will try to help me So here is the situation. I am building webpage that displays a clock , a ticker box and a countdown(alarm clock). I have found many previously coded alarm clocks/countdown timers but they dont do what i need. Then what do you need you might be asking yourself?! - I need a countdown timer with background in MySQL database(there will be multiple events in that database) and then checks which is the next one( Alarms will be in HH:MM format so they can be activated every day), after the check it displays a countdown(logical eh?) until that event - when it reaches that event it should redirect to some other site(which will return user to the same site after 15 min pause) and then All over again, check which is next, countdown , redirect , AGAIN This website is designed not to be clicked or anything - it should work by itself. Are YOU able to help me? (Just a fair warning - Im a newb in javascript so dont be too harsh on me) I'm trying to convert A world Population Counter from Flash into HTML/Javascript. But I'm having difficulties and It would be great if someone can help me out. The sample show a analog clock, But the html version I want should use just a digital clock, it's simpler I think http://www.webstylelabs.com/worldclock2.swf http://www.webstylelabs.com/actionscript.txt Here is my code, http://www.webstylelabs.com/clock.html So just plain input digital counter is ok I appreciate any help if you take a look at this site here you can see that it no longer scrolls or even displays content, but here it does. I'll bet there's a quick fix here, but not sure what it is. Any ideas?
Hi, I have a webpage with a world clock. On the clock page are 12 buttons (World Cities). When the user clicks these buttons. The time for the relevant world city is displayed. (The time is updated by an on.click function for each individual button. That either subtracts or adds the hours from GMT. For example. If the time is GMT 18:00:00. The user clicks the Paris button and the function adds 1 hour to result in 19:00:00) However. If the GMT time is for example 21:00:00 and the user clicks the Tokyo button (GMT+9 hours). The time displayed is 30:00:00. So I have been trying to work out how I can stop the time adding past 23:59:59. This is probably so simple which is probably why I cant find any help online. It has stumped me and any help would be appreciated. I have copied and pasted my code below in the hope that helps. Thanks in advance if you can offer any advice. Code: <script>
function start() {
GMToffset = 0;
t=setInterval('digitalclock()',500);
}
function digitalclock()
{
var today=new Date();
var hours=today.getHours() + GMToffset;
var minutes=today.getMinutes();
var seconds=today.getSeconds();
minutes=checkTime(minutes);
seconds=checkTime(seconds);
hours=checkTime(hours);
document.getElementById('txt').innerHTML=hours+":"+minutes+":"+seconds;
}
function checkTime(i)
{
if (i<10)
{
i="0" + i;
}
return i;
}
function updatetime1() {
GMToffset = -3;
}
function updatetime2() {
GMToffset = -4;
}
function updatetime3() {
GMToffset = -7;
}
function updatetime4() {
GMToffset = -10;
}
function updatetime5() {
GMToffset = -11;
}
function updatetime6() {
GMToffset = -13;
}
function updatetime7() {
GMToffset = +9;
}
function updatetime8() {
GMToffset = +8;
}
function updatetime9() {
GMToffset = +7;
}
function updatetime10() {
GMToffset = +1;
}
function updatetime11() {
GMToffset = +0;
}
function updatetime12() {
GMToffset = +3;
}

So after some studying I have a pretty decent method using objects. I built it so that you hit the first number, then you would hit a plus or minus then the second number. The problem is just getting the buttons to define variables and run functions. Quote: <html> <head> <script type="text/javascript" > x=10; h=1; var numbs = new Const(x) function Const(one){ this.x=one; ADD(this.x) if(h=1){ function ADD(a){ y=5; b=y+a; alert(b); }}} </script> </head> <body> <input type="button" value="1" onclick="needs to run all that AND set x=1 and h=1"> </body> </html> Also I plan on going back and making y, which is the second number you're adding, an object. For now I'm just setting it equal to something so I don't have to mess with it. I have been looking for someone that can make this for me. I need a program made to register accounts to this url > Register :: The Pokemon Moon RPG :: Online Pokemon RPG Game What it needs to do: Needs to use proxies Needs to use a proxy for 1 account, so say 500 accounts it needs to have 500 different proxies. Needs to be able to have a timer to make it wait ie. Wait between 1min - 3 hours between account Needs to randomize account names(that people would make their names) Needs to randomize account passwords If possible make it able to make the account, then log in to it and sit on the account for random times ie. 4 minutes or 4 hours or longer of shorter. I will donate money to whoever does this for me, I also have something else I would like to be made, so if whoever wants to be donated to twice just let me know!

Join Date Feb 2009 Posts 28,310 Thanks 82 Thanked 4,754 Times in 4,716 Posts Completely unethical. And probably illegal, in the sense that it violates the "Terms of Use" he Terms Of Use :: The Pokemon Moon RPG :: Online Pokemon RPG Game Users must not engage in any sort of attempts to hack this website and/or its users. (And we all know what the "something else" you want made will be. Something that gets credits in the game, somehow.) What is the point of this? Why does anybody want to cheat at an online game where there is no money reward involved. I mean I could understand trying to hack a poker site if real money is involved. But just for credits, in a game? *sigh* If I win a game, I want to know I won it the right way, not by cheating. And, if you really do get high on cheating, I'd think you'd at least want to do so with your OWN cheat, not by just buying one. I simply do not understand the attraction to this kind of stuff. Hello. I am trying to stop and then start my clock, but something goes wrong Code: <script type="text/javascript">

Any help will be appreciated. Hey guys. I made a chat client today (my first one and it's pretty sweet so far) I have a speed problem though http://xonicgames.com/hudson/chat.php Once there are ~20+ posts it starts getting slow (at least on my connection) It does an ajax request every 500 seconds (dont know if that should be slowed down or not) What can I do to speed it up? Thanks Hello all! For the past few days I've been having trouble trying to figure out how to do something. I want to code a world population clock similar to the one here, but simpler: I want the user to be able to choose future years up to 2020 (just years, not months/days), and have the population grow by 1 percent each year. So far I have a code for the world population, but I have no clue where to begin in terms of making a list of the years with the option to increase the population. Could anyone point me in the right direction? I'd appreciate any help! Heres the code I have: <body> <script type="text/javascript"> function maind(){ startdate = new Date() now(startdate.getYear(),startdate.getMonth(),startdate.getDate(),startdate.getHours(),startdate.getM inutes(),startdate.getSeconds()) } function ChangeValue(number,pv){ numberstring ="" var j=0 var i=0 while (number > 1) { numberstring = (Math.round(number-0.5) % 10) + numberstring number= number / 10 j++ if (number > 1 && j==3) { numberstring = "," + numberstring j=0} i++ } numberstring=numberstring if (pv==1) {document.getElementById("worldpop").innerHTML=numberstring } } function now(year,month,date,hours,minutes,seconds){ startdatum = new Date(year,month,date,hours,minutes,seconds) var now = 5600000000.0 var now2 = 5690000000.0 var groeipercentage = (now2 - now) / now *100 var groeiperseconde = (now * (groeipercentage/100))/365.0/24.0/60.0/60.0 nu = new Date () schuldstartdatum = new Date (96,1,1) secondenoppagina = (nu.getTime() - startdatum.getTime())/1000 totaleschuld= (nu.getTime() - schuldstartdatum.getTime())/1000*groeiperseconde + now ChangeValue(totaleschuld,1); timerID = setTimeout("now(startdatum.getYear(),startdatum.getMonth(),startdatum.getDate(),startdatum.getHours( ),startdatum.getMinutes(),startdatum.getSeconds())",200) } window.onload=maind </script> Current world population (estimated): <span id="worldpop" style="font-weight: bold"></span>. </body> Hello, I'm somewhat new to JavaScript and for my website, I decided to make a clock for the website in this format: Saturday, October 17, 2009 5:56:14 p.m. The only issue is that it won't update every second. Below is the coding: External JavaScript: Code: function dateClock()
{
// Coding
}
setTimeout("dateClock()", 1000);
HTML: Code: ...
<script src="date.js" type="text/javascript">
</script>
</head>
<body>
<script type="text/javascript">
document.write("<p style='margin:-15px 0px;background-color:black;position:fixed;padding:5px;'>"+Day+", "+Month+" "+date+", "+Year+"<br />"+Hour+":"+Minute+":"+Sec+" "+Suffix+"</p>");
</script>
What can I do to make it update? Thanks. I figured if there was one it would be a Javascript but does anyone know of a countdown clock that almost looks like a counter/turnstile number row? Like this sorta: I've been looking for one where I have the numbers look just like that and 'push' upward as the times (days, minutes, seconds) go on. Hopefully someone knows of a script >< Thanks alot!!! Hello, I would like help about my problem. I want to find the proper function to manage a clock .
