JavaScript - Countdown Based On Server's Time
Hey.
I'm currently looking for a countdown script, which is based on the server's time. I've only found scripts, that's based on the local computer's time, which means the output of the script changes, when the time on the computer is changed. And I want to make a public announcement which counts down to something - and should output the same at every person. I'm not that familiar with JavaScript, I know some jQuery - if anyone can supply any links or can help me with this, I'd appreciate it. Similar Tutorials1 down vote favorite I do have the countdown script (see link below) to display the time between current time and the date given in real-time. However, I want to achieve to display the time difference between a given start and end time. Right now, it calculates from the current server time to the end time. I want to be able to set up my own start time and end time. Here is what I have: http://jsfiddle.net/BgEtE/ thank you for help hi, i am now playing with the time. can you please tell me how to make the time move in downwards, i mean a countdown like format, e.g the time will start countdown and end in 2 days? here's my initial noob code for creating time Code: <script type="text/javascript">
var today = new Date();
h = today.getHours();
m = today.getMinutes();
s = today.getSeconds();
function showDate(){
if(document.getElementById('but').value = "locked"){
h = checktime(h);
m = checktime(m);
s = checktime(s);
}
document.getElementById('t').innerHTML = h +":"+m+":"+s;
}
function checktime(i){
if(i < 10){
i = "0" + i;
}
return i;
}
function ocl(){
var x = true;
if(x){
document.getElementById('but').value = "locked";
showDate();
}
}
function mo(){
document.getElementById('but').value = "lock me ?";
x = false;
}
</script>
<h3>
<a id="t"></a>
</h3>
<input type="button" id="but" value="unlocked" onmouseover="mo();" onclick="ocl();" />
Hi I hope I hit the topic I have a problem in java script i need it for an online game that I develop but not as I do not go javasript countdown or can help me I need a timer that counts down and ceases to move to the other side but not when Refresh to go back and allow you to set time thanks in advance
I am new to JavaScript and am enrolled in an introductory class. My assignment is to create JavaScript for a Web page that counts down the time left until several events. I have been working on this code for several hours now, and I have done everything the textbook instructs me to do, yet when I load the Web page I still get blank fields where my countdown info should be. I would really appreciate it if someone could look through the code I've created and give me some pointers. I have an .htm file and an external .js file. The .htm file is: Code: <html>

hi, can some one help me how to get the time and date difference? given two time and date with the following format like in textbox A: 2011-05-03 17:35:47.0 and textbox B: 2011-05-03 16:35:47.0 then the output would be: 0 days, 1 hour, 0 minutes, 0 seconds regards, verve Can someone help me modify this script be set to a specific Time Zone rather than picking up the time from the local machine? I want it to countdown to 6:00 am EST. http://javascript.internet.com/time-...countdown.html Can anyone tell me what to add where if it is possible? Thank you in advance. Hello everyone, I am completely new to javascripts. I want to have a count down timer on my webpage. I already found a script, but it does not do everything I want it to do. I couldn't find a script that did everything I need. I need it to do the following things: - Use the time zone GMT+1 - Reset everyday at a specific time - From 15:00 till 17:30: A countdown (so it shows 2 hours and 30 minutes from the start and count's down to 0 (which will be 17:30) - During 15:00 till 17:30 it shows: "The game is playing" - Once it is 17:30 I want it to reset and countdown till the next day 15:00 - From 17:30 till 15:00 next day it says: "The game will start in" So it is actually 2 countdown clocks in one javascript. One countdown from 15:00 to 17:30 (whilst the game is playing) and one directly starting after it from 17:30 till 15:00 next day. But both are displayed on the same spot. The countdown will be in text. No buttons or fancy images etc. Hope you can help me out. Thanks Code: <html>

I have a site where users enter there certain timezome (+1, +4, -8 etc) and i want to display a clock with the local time on their profile page so when people view there profile they can see currently what time it is for them. I currently a have this. Code: function timeclock()
{
var t=setTimeout("startclock()",500);
}
function startclock()
{
var x = new Date();
var hour = x.getHours();
var min = x.getMinutes();
var sec = x.getSeconds();
if (hour<10){hour="0"+hour}
if (min<10){min="0"+min}
if (sec<10){sec="0"+sec}
document.getElementById("clock").innerHTML=hour+":"+min+":"+sec;
timeclock();
}
Is it possible to alter the date dependent on the timezone? Maybe put startclock(timezone) andchange it to new Date(timezone);? Hello all. I have created a 2 frame site where I want the top frame (header) to redirect the other frame (main) to a different page depending on the date, time, and second. For example, on 12 FEB at 07:00:00, I would like the header frame to redirect the main frames page to EmmasBday.html; in which I would be alerted of my little sisters Birthday. This is for personal use and isn't going to be hosted online so I will just use JavaScript, it's basically a simple system to remind me of crucial events at certain times and dates so I don't forget them. The same events will apply every year, so there is no need to programme in specific years although having the option could prove useful. I am aware of other alternatives to achieve this, but would very much like to work with JavaScript; as I can expand it. As I state, this is for personal use and therefore won't be hosting it; I will use JavaScript throughout and cannot use anything else like PHP, Perl, etc. I am aware JavaScript takes the time & date from the computer hosting it (unlike PHP), which is fine. So, for example; at 14:30:00 I will be informed to get dinner; and at 15:00:45 I'll be informed to study. The knowledge you guys have presented so far is phenomenal, and I couldn't think of anybody better to ask for assistance. Anyway, I hope you can resolve my problem and I'm looking forward to a response! Thanks for your concern, you brain Gods you! AHa. Hi Guys, I am looking for a script to change text on a page based on the time of day. From 9am - 5pm weekdays I would like the page to display 'Open', and outside of that window to display 'Closed'.

Hello I am trying to do something similar to this post http://www.codingforums.com/showthread.php?t=168903 except I need it to be dependent on the hour and minute. Background: I am trying to create a schedule website, the schedule has say 20 items and I want it to display the current "active" event in the schedule, 1 previous event and 3 future events so a total of 5 items from the schedule. An event can range from 30 minutes to 2 hours long, so simply using the above code will not work. It needs to take the minutes into consideration as well. Let me know if you have additional questions. EDIT: 17-Mar-12 @ 12:37PM I would rather not use a bunch of if statements. (http://www.codingforums.com/showthread.php?t=250358) The schedule could change mid day so having to go through and edit a bunch of if statements would not be ideal I have a javascript controlling the display of a DIV that I did a while back that needs a bit more tweaking to add function to hide the DIV on specific holidays. As it is now, by default, the DIV is being hidden unless it is M-F between 8:00AM-6:00PM: Code: <script type="text/javascript">
onload=function(){
var rightNow = new Date();
var day = rightNow.getDay();
var hour = rightNow.getHours();
var minute = rightNow.getMinutes();
var formDisplay = 'none'; // unless we see otherwise
var forwardDisplay = 'block'; // unless we see otherwise
if(day==1 || day==2 || day==3 || day==4 || day==5) { // if chat is avalable on these days
if((hour>=8) && (hour<=17)) // if chat is avalable between these times
formDisplay = 'block', forwardDisplay = 'none';
}
document.getElementById('ChatForm').style.display = formDisplay;
document.getElementById('ChatForward').style.display = forwardDisplay;
}
</script>
Im assuming that I would just add more else if statements, but not really sure the cleanest way to assign specific dates using this format. Any help is appreciated I'm trying to add a body class of 'day' if it's 6am-5pm and 'night' if it's 5pm-6am based on the user's local time. I tried the following but it didn't work. Any ideas? In the <head> Code: <script>
function setTimesStyles() {
var currentTime = new Date().getHours();
if(currentTime > 5 && currentTime < 17) {
document.body.className = 'day';
}
else {
document.body.className = 'night';
}
}
</script>
Code: <body onload="setTimeStyles();"> Also, is there a more elegant way to achieve what I need? I have the following JavaScript (see below). The script requests an XML file from the server and displays it on the page. The script works fine when the requested XML file is stored on the same server as the script. The problem is when I try requesting an XML file from an external server such as the National Weather Service. I get an error. If I take the XML file from the National Weather Service and save it to my server it works. Why can't I use my script to request XML files stored on external servers? Thanks in advance for any help.

Hi Code: var err_str="";
function validate_grid(value,id,ind)
{
$("#result").html(" ").show();
if(ind==1 || ind==2)
{
var patt=/^([0][0-9]|[1][0-9]|[2][0-3])[:]{1}[0-5][0-9]$/;
if(!patt.test(value))
{
mygrid.setCellTextStyle(id,ind,"background-color:yellow;");
if(err_str!="")
err_str+="\n"+(ind+1)+".Enter numbers and : only..";
else
err_str=(ind+1)+".Enter numbers and : only";
return false;
}
else
{
mygrid.setCellTextStyle(id,ind,"background-color:white;");
return true;
}
}
}
alert(err-str);
here ind==1 is from_time and ind==2 is to_time,i need to validate time as to_time must be always greater than from-time,if condition fails an alert msg should populate.time format is[05:00]as it is in string format im unable to do the validation for it.(ex:from-time=08:00 to-time=07:59 condition fails) thank you. Hello im using dhtmlx grid in this cells i have from time and to time (i.e ind==1 and ind==2) i need to validate time where to-time must be greater than from-time else it should alert an message,i have writeen a normal Regular expression for the time validation.as the time is i string format i.e[05:00],please can any one send me code for that. Code: var err_str="";

I need help to make a Server to server connection I already have a server connected to clients, clients send msgs and it echoes back to all of them and now i want when a client sends a msg it echoes on his server and the other server too .. so when any of the clients on any of the servers sends a msg it is broadcasted all over the servers to all clients This is my SERVER code Code: import java.io.*;
import java.net.*;

// socket, input stream

int port_number = 6000;
if (args.length < 1) {
System.out.println("Server Started \n" + "Now using port number="
+ port_number);
} else {
port_number = Integer.valueOf(args[0]).intValue();

// given port
try {
serverSocket = new ServerSocket(port_number);
