Example which is not working:
<div id="clockDisplay"></div>
<script type="text/javascript" language="javascript">
function renderTime() {
var currentTime = new Date();
var h = currentTime.getHours();
var m = currentTime.getMinutes();
var s = currentTime.getSeconds();
setTimeout('renderTime()',1000);
if (h < 10) {
h = "0" + h;
}
if (m < 10) {
m = "0" + m;
}
if (s < 10) {
s = "0" + s;
}
var myClock = document.getElementById('clockDisplay');
myClock.textContent = 'Local time:\n' + h + ":" + m + ":" + s;
myClock.innerText = 'Local time:\n'+ h + ":" + m + ":" + s;
}
renderTime();
</script>..
The ---> myClock.innerText = 'Local time:\n'+ h + ":" + m + ":" + s; <---
separates Local time from the digits in Chrome.
However ---> myClock.textContent = 'Local time:\n' + h + ":" + m + ":" + s; <---
is supposed to do the same just in Firefox but it doesn't work.
I have tried with \n\r, \r\n, /\n/ and /\r/ Nothing worked for me..
Use <br> as line break. HTML collapses whitespace:
myClock.innerHTML = 'Local time:<br>' + h + ":" + m + ":" + s;

So the code/script is below. I want it to update without having to refresh the page. I tried putting it in a loop but the page just never loaded. Can anyone help?
Thanks
var dt = new Date();
document.getElementById("datetime").innerHTML = (("0" + dt.getDate()).slice(-2)) + "." + (("0" + (dt.getMonth() + 1)).slice(-2)) + "." + (dt.getFullYear()) + " " + (("0" + dt.getHours()).slice(-2)) + ":" + (("0" + dt.getMinutes()).slice(-2)) + ":" + (("0" + dt.getSeconds()).slice(-2)) + ":" + (("0" + dt.getMilliseconds()).slice(-2));
setinterval(timer, 1000);
Modify the code like this
setInterval(function(){
var dt = new Date();
document.getElementById("datetime").innerHTML = (("0"+dt.getDate()).slice(-2)) +"."+ (("0"+(dt.getMonth()+1)).slice(-2)) +"."+(dt.getFullYear()) +" "+ (("0"+dt.getHours()).slice(-2)) +":"+ (("0"+dt.getMinutes()).slice(-2)) +":"+ (("0"+dt.getSeconds()).slice(-2)) +":"+ (("0"+dt.getMilliseconds()).slice(-2));
}, 1);
<div id="datetime">
</div>
This will also work

var d = new Date();
var h = d.getHour();
var m = d.getMinute();
var s = d.getSecond();
if (h == 12) {
alert(h + ":" + m + ":" + s + " PM");
} else {
alert(h + ":" + m + ":" + s + " AM");
}
What should i do?
Should i change the d.getMinute() to d.getMin()?
Thank you all
The methods are all supposed to be pluralized:
var d = new Date();
var h = d.getHours();
var m = d.getMinutes();
var s = d.getSeconds();
if(h == 12) {
alert(h+":"+m+":"+s+" PM");
} else {
alert(h+":"+m+":"+s+" AM");
}

I am making a simple time calculator in javascript. I have converted the times into 12-hour instead of 24 hour time for simplicity, however the code I have for calculating am/pm always shows am. Any reason why this would be happening?
Here is my code:
function solveTime(x) {
var suffixSolve = (utcHours + x) % 24;
var suffix = "am";
if (utcHours > 12) {
var suffix = "pm";
}
if (utcMinutes == 0) {
utcMinutesLead = "00";
}
if (utcMinutes < 10) {
utcMinutesLead = "0" + utcMinutes;
}
var timeSolve = (((utcHours + x) + 11) % 12 + 1);
var timeTotal = timeSolve + ":" + utcMinutesLead + " " + suffix;
var utcMod = x;
if (utcMod > 0) {
utcMod = "+" + utcMod;
}
document.getElementById(x).innerHTML = "(UTC" + utcMod + ") " + timeTotal;
}
and here is the code behind utcHours
var masterTimeUTC = new Date();
var utcHours = masterTimeUTC.getUTCHours();
var utcMinutes = masterTimeUTC.getUTCMinutes();
var utcSeconds = masterTimeUTC.getUTCSeconds();
var utcMinutesLead = masterTimeUTC.getUTCMinutes();
Example here: http://codepen.io/markgamb/pen/gwGkbo
The issue is you should be checking whether suffixSolve is greater than 12 instead of utcHours, because utcHours does not change due to the value of x. Since you can shift the hours forward and backwards, I created a variable shift to handle that.
function solveTime(x) {
if (x < 0) {
var shift = 24 + x;
} else {
var shift = x;
}
var suffixSolve = (utcHours + shift) % 24;
var suffix = "am";
if (suffixSolve > 12) {
suffix = "pm";
}
if (utcMinutes == 0) {
utcMinutesLead = "00";
}
if (utcMinutes < 10) {
utcMinutesLead = "0" + utcMinutes;
}
var timeSolve = (((utcHours + x) + 11) % 12 + 1);
var timeTotal = timeSolve + ":" + utcMinutesLead + " " + suffix;
var utcMod = x;
if (utcMod > 0) {
utcMod = "+" + utcMod;
}
document.getElementById(x).innerHTML = "(UTC" + utcMod + ") " + timeTotal;
}
var masterTimeUTC = new Date();
var utcHours = masterTimeUTC.getUTCHours();
var utcMinutes = masterTimeUTC.getUTCMinutes();
var utcSeconds = masterTimeUTC.getUTCSeconds();
var utcMinutesLead = masterTimeUTC.getUTCMinutes();
solveTime(4);
solveTime(0);
solveTime(-8);
<div id="4"></div>
<div id="-8"></div>
<div id="0"></div>
I ran into a snag in my code, the code below is for a JavaScript clock which works perfectly:
function renderTime() {
var currentTime = new Date();
var diem = "AM";
var h = currentTime.getHours();
var m = currentTime.getMinutes();
var s = currentTime.getSeconds();
if(h == 0) {
h = 12;
} else if(h > 12) {
h = h - 12;
diem = "PM";
}
if(h < 10) {
h = "0" + h;
}
if(m < 10) {
m = "0" + m;
}
if(s < 10) {
s = "0" + s;
}
var myClock = document.getElementById('clockDisplay');
myClock.textContent = h + ":" + m + ":" + s + " " + diem;
myClock.innerHTML = h + ":" + m + ":" + s + " " + diem;
myClock.innerText = h + ":" + m + ":" + s + " " + diem;
setTimeout('renderTime()',1000);
}
renderTime();
However I am trying to do it slightly different now like this:
function makeTime() {
var currentTime = new Date();
var diem = "AM";
var h = currentTime.getHours();
var m = currentTime.getMinutes();
var s = currentTime.getSeconds();
if(h == 0) {
h = 12;
} else if(h > 12) {
h = h - 12;
diem = "PM";
}
if(h < 10) {
h = "0" + h;
}
if(m < 10) {
m = "0" + m;
}
if(s < 10) {
s = "0" + s;
}
var clock = document.getElementById('clock');
clock.innerHTML = "<h1>"+h+":"+m+":"+s+":"+diem+"</h1>";
myClock.textContent = "<h1>"+h+":"+m+":"+s+":"+diem+"</h1>";
myClock.innerText = "<h1>"+h+":"+m+":"+s+":"+diem+"</h1>";
setTimeout('makeTime()',1000);
}
makeTime();
This one works, however does not update like the other one, you have to manually refresh the page.
What am I doing wrong?
You continue to refer to myClock in your second version, when you've renamed the variable to clock:
var clock = ...
clock.innerHtml = ...
myClock.textContent = "<h1>"+h+":"+m+":"+s+":"+diem+"</h1>";
myClock.innerText = "<h1>"+h+":"+m+":"+s+":"+diem+"</h1>";
setTimeout('makeTime()',1000);
This is causing errors (reference error: myClock is not defined) which is preventing the flow of execution from reaching your setTimeout call.
You should learn to use the tools available to you. Every browser has a method of reporting JavaScript errors to developers. Open the developer console in Webkit/IE10, or Firebug in Firefox, you'll see these errors and exactly where they're happening in your code.
So I followed a pretty strait-forward video tutorial on adding a clock in your webpage through JS. I have the exact same code, but it's not working on mine. Any suggestions? Thank you!
This is my code:
<body>
<div id="clockDisplay">00:00</div>
<!-- JAVASCRIPT starts here -------------------------------------------------------->
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.6.2/jquery.min.js"></script>
<script type="text/javascript" language="JavaScript">
$(window).load(function renderTime() {
var currentTime = new Date () ;
var diem = "AM" ;
var h = currentTime.getHours() ;
var m = currentTime.getminutes() ;
var s = currentTime.getSeconds() ;
if (h == 0) {
h = 12;
} else if (h > 12) {
h = h -12;
diem = "PM" ;
}
if (h < 10) {
h = "0" + h;
}
if (m < 10) {
m = "0" + m;
}
if (s < 10) {
s = "0" + s;
}
var myClock = document.getElementyID('clockDisplay');
myClock.textContent = h + ":" + m + ":" + s + " " + diem;
setTimeout(renderTime()' ,1000) ;
};
renderTime() ;
</script>
<!-- JAVASCRIPT ends here --------------------------------------------------------->

You have a syntax error (quote mismatch) in your setTimeout code. You should never use a string as the first parameter of setTimeout.
setTimeout(renderTime, 1000);
And you don't need the $(window).load() if you put your Javascript code after the element with id="clockDisplay"
function renderTime() {
...
}
renderTime();
These need to be changed as well.
getElementById()
getMinutes()
Don't know what tutorial your following but I would change this line:
myClock.textContent = h + ":" + m + ":" + s + " " + diem;
to this:
myClock.innerHTML = h + ":" + m + ":" + s + " " + diem;
Too many things to fix here, this is my code :
<body>
<div id="clockDisplay">00:00</div>
<!-- JAVASCRIPT starts here -------------------------------------------------------->
<script type="text/javascript" language="JavaScript">
function renderTime() {
var currentTime = new Date () ;
var diem = "AM" ;
var h = currentTime.getHours() ;
var m = currentTime.getMinutes() ;
var s = currentTime.getSeconds() ;
if (h == 0) {
h = 12;
} else if (h > 12) {
h = h -12;
diem = "PM" ;
}
if (h < 10) {
h = "0" + h;
}
if (m < 10) {
m = "0" + m;
}
if (s < 10) {
s = "0" + s;
}
var myClock = document.getElementById('clockDisplay');
myClock.textContent = h + ":" + m + ":" + s + " " + diem;
}
window.onload = renderTime;
setInterval(renderTime ,1000) ;
</script>

I have created a digital clock on my personal developing website but its not animated...
My javascript is below:
07:23:45 PM
<script>
function webClock() {
var pos = "PM";
var pickTime = new Date();
var h = pickTime.getHours();
var m = pickTime.getMinutes();
var s = pickTime.getSeconds();
if(h == 0){
h = 12;
}else if(h>12){
h = h-12;
pos="AM";
}
if(h<10){
h = "0" + h;
}
if(m<10){
m = "0" + m;
}
if(s<10){
s = "0" + s;
}
document.getElementById('MyClock').innerHTML= h + ":" + m + ":" + s + " " +"pos";
setTimeout(webClock, 500);
}
webClock();
}
</script>
