Kami 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.

I want to make a javascript clock (using Server time and not user computer time). After searching I have found the code on http://www.elated.com/articles/creat...ascript-clock/ The Code is: PHP Code: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd"> <html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" lang="en"> <head> <style type="text/css"> #clock { font-family: Arial, Helvetica, sans-serif; font-size: 0.8em; color: white; background-color: black; border: 2px solid purple; padding: 4px; } </style> <script type="text/javascript"> <!-- function init ( ) { timeDisplay = document.createTextNode ( "" ); document.getElementById("clock").appendChild ( timeDisplay ); } function updateClock ( ) { var currentTime = new Date ( ); var currentHours = currentTime.getHours ( ); var currentMinutes = currentTime.getMinutes ( ); var currentSeconds = currentTime.getSeconds ( ); // Pad the minutes and seconds with leading zeros, if required currentMinutes = ( currentMinutes < 10 ? "0" : "" ) + currentMinutes; currentSeconds = ( currentSeconds < 10 ? "0" : "" ) + currentSeconds; // Choose either "AM" or "PM" as appropriate var timeOfDay = ( currentHours < 12 ) ? "AM" : "PM"; // Convert the hours component to 12-hour format if needed currentHours = ( currentHours > 12 ) ? currentHours - 12 : currentHours; // Convert an hours component of "0" to "12" currentHours = ( currentHours == 0 ) ? 12 : currentHours; // Compose the string for display var currentTimeString = currentHours + ":" + currentMinutes + ":" + currentSeconds + " " + timeOfDay; // Update the time display document.getElementById("clock").firstChild.nodeValue = currentTimeString; } // --> </script> </head> <body onload="updateClock(); setInterval('updateClock()', 1000 )"> <div> <span id="clock"> </span> </div> </body> </html> The problem is that it (the code above) is using the users computer time. (I found (in the comments of http://www.elated.com/articles/creat...ascript-clock/) that I should use: PHP Code: var currentTime = [serverValue goes here]; But I don't really know what should I put in the "serverValue goes here" ..... ) So how can I make this code to use the server time (and not the users time)? Any Suggestion Will Be Helpfull Hi All, i want to achieve an effect like the following, please help 1. i want to get the current time, possibility no from client computer ( sometimes their time is wrong)? i dont know whether can achieve but if cannot, then never mind, just get from client computer. 2. for example now is 1:25 am, i want to generate dynamically every half an hour timing from 2 am(round up) till for example 11 am something like <select> <option>2:00</option> <option>2:30</option> ................ <option>11:00</option> </select> for me this is a bit complicated, anybody can help me? <option>3:00</option> Hello, I was given an assignment to change an existing form into one that will automatically perform calculations and since I have never done this before I am learning as I go. The form needs to do the following: gr_percentage = list_percentage + sale_percentage gr_comm_dollars = gr_percentage * price list_comm_dollars = list_percentage * price and so on. I also need to calculate the following gr_total_dollars = gr_comm_dollars + gr_fixed_dollars + gr_bonus_dollars (all of which will be calculated on entries for the sale and list portions). I though that I had it figured out but upon testing the form it does nothing. Please let me know what I need to change in order for the calculations to work properly. Thank you Code: <script type="text/javascript">
function calculate(Id)
{
var price = document.getElementById('price').value;
var REO_list_percentage = document.getElementById('REO_list.percentage').value;
var REO_sale_percentage = document.getElementById('REO_sale_percentage').value;
var REO_sale_dollars = document.getElementById('REO_sale_dollars').value

var gr_comm_dollars = document.getElementById('gr_comm_dollars').value;
var gr_bonus_dollars = document.getElementById('gr_bonus_dollars').value;

document.getElementById('gr_comm_percentage').value=REO_list_percentage + REO_sale_percentage;
document.getElementById('gr_comm_dollars').value=gr_comm_percentage/100*price;

Greetz, I am new to JS and using code that someone gave me. I have cleaned up the code, made it standard compliant and tailored it to my need. The code is for an ultra basic picture gallery. The code is almost perfect, but there is one undesirable effect in which when an image is selected from the thumbnail gallery, the thumbnail dissapears as I am guessing its the same element, just blown up. What I would like to know is how I can stop it from happening? I will post the full output of the HTML file. I have also uploaded zip file which contains the HTML file and two images, so one may see the compiled page as I do. Zip file (Note: STUPID hosting site placed the DOWNLOAD button right under "MP3 ringtones"... Clicking download will not take you to some premium SMS service or anything like that): http://qfs.mobi/f31666 Code: Code: <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN"

Much appreciated! http://whitelemondesigns.com/test/about.html I can't for the life of me figure out where I'm going wrong with the scroll bar... I think I've got all the html and css correct, I have to assume there's a javascript error but I can't find it... could I have a javascript conflict? If you guys have any insight I would appreciate it, this is driving me up a wall. I downloaded a popup datepicker from javascriptkit.com. All great but can't take the time out of the footer. I only want the date to show, and once selected, I would like the field to be filled with "Day, Date, Month, Year" (no time). Code is as follows: Code:
function show_calendar(str_target, str_datetime) {
var arr_months = ["January", "February", "March", "April", "May", "June",
"July", "August", "September", "October", "November", "December"];
var week_days = ["Su", "Mo", "Tu", "We", "Th", "Fr", "Sa"];
var n_weekstart = 1; // day week starts from (normally 0 or 1)
var dt_datetime = (str_datetime == null || str_datetime =="" ? new Date() : str2dt(str_datetime));
var dt_prev_month = new Date(dt_datetime);
dt_prev_month.setMonth(dt_datetime.getMonth()-1);
var dt_next_month = new Date(dt_datetime);
dt_next_month.setMonth(dt_datetime.getMonth()+1);
var dt_firstday = new Date(dt_datetime);
dt_firstday.setDate(1);
dt_firstday.setDate(1-(7+dt_firstday.getDay()-n_weekstart)%7);
var dt_lastday = new Date(dt_next_month);
dt_lastday.setDate(0);
// html generation (feel free to tune it for your particular application)
// print calendar header
var str_buffer = new String (
"<html>\n"+
"<head>\n"+
" <title>Calendar</title>\n"+
"</head>\n"+
"<body bgcolor=\"White\">\n"+

Thanks for any help!!! Ruth Hi guys. I'm trying to make a small bit of scripting that will show the current time, updating once every second. What I need is the following: 1. Multiple timezones or GMT offsets (just put me on the right path, I can code them in, 2. Daylight savings time taken into consideration (only for Australia), adding the 1 hour during the times it is needed, 3. Text to show "Open" and "Closed" during different times (open during 8am to 5pm and closed if not 8am to 5pm.) I have the following code as a start, but I am completely stuck with how to get the rest of what I need! Any help would be appreciated. <h4>Victoria <script type="text/javascript"> <!-- var currentTime = new Date() var hours = currentTime.getHours() var minutes = currentTime.getMinutes() if (minutes < 10){ minutes = "0" + minutes } document.write(hours + ":" + minutes + " ") if(hours > 11){ document.write("PM") } else { document.write("AM") } //--> </script> <script type="text/javascript"> <!-- var currentTime = new Date() var hours = currentTime.getHours() var minutes = currentTime.getMinutes() if (minutes < 10){ minutes = "0" + minutes } if(hours > 11){ document.write("True") } else { document.write("False") } //--> </script> </h4> Cheers in advance. Dale. Hi, I am trying to build a counter in javascript. The time on the counter should be displayed in hours, minutes and seconds<24:00:00>. When the counter reaches 00:00:00, it should stop.I read some books and they say that I must use the setInterval function to implement the timer. The problem is I don't know how to begin it. Could anybody give me some guidance on where to begin to do something like this. My javascript skills are basic as you can probably tell but I do like to learn it step by step. Thanks in advance Can anyone help? i'm trying to find some references and resources on how to hide a link at a certain time and show the link again at a certain time. eg: from 12pm to 2pm the link will be display, users are able to click the link. after 2pm the link will not be displayed[hide] or the when click on the link error message will be shown. plz help. thanks! hi i am using jquery for ajax request response. Is there any javascript functions which can cause some time delay like Code: ajaxStart(function() {
showAnimation();
delay(5000s):
});
I am trying to make a simple calculator to calculate dBm, Vpp, Vrms. It is basically a conversion calculator. I am brand new to JavaScript and tried to follow a tutorial but I'm coming up short. I will post both my .js and .html code below. My issue is that when I hit the "Calculate" button nothing happens. Here is the javascript. It has a main calculate function and a function that gives me a log base 10 method. Code: //Main Calculation
function calculate() {
if(dBm === null && Vpp === null){
var calc = document.getElementById('ecalc');
var Vpp2 = (4*Vrms)/Math.sqrt(2);
var dBm2 = 20 * (log10(Vpp/(Math.sqrt(0.008*Z))));
var Vrms2 = Vrms;
return false;
}
else if(Vpp === null && Vrms === null){
var calc = document.getElementById('ecalc');
var Vpp2 = Math.sqrt(0.008*Z)*Math.pow(10,(dBm/20));
var Vrms2 = (Math.sqrt(2)/2)*(Vpp/2);
var dBm2 = dBm;
return false;
}
else if(dBm === null && Vrms === null){
var calc = document.getElementById('ecalc');
var dBm2 = 20 * (log10(Vpp/(Math.sqrt(0.008*Z))));
var Vrms2 = (Math.sqrt(2)/2)*(Vpp/2);
var Vpp2 = Vpp;
return false;
}
calc.Vpp2.value = Vpp2;
calc.Vrms2.value = Vrms2;
calc.dBm2.value = dBm2;
return false;
}
//Log base 10 Function
function log10(val) {
return Math.log(val) / Math.log(10);
}
Here is the HTML. It has the form in it. As you can see there are 4 inputs. Z is required and only one of the other values can be entered (hence the if statements in the js. Code: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <meta content="text/html; charset=utf-8" http-equiv="Content-Type" /> <title>Untitled 1</title> <script type="text/javascript" src="Calculate.js"> </script> </head> <body> <form id="ecalc" action="#"> <table align="center"border="1"> <tr> <td colspan="2" align="center"> Enter a Z value and one other value. </td> </tr> <tr> <td align="right">dBm: </td> <td align="left"><input type="text" name="dBm" size="20" /></td> </tr> <tr> <td align="right">Vpp: </td> <td align="left"><input type="text" name="Vpp" size="20" /></td> </tr> <tr> <td align="right">Vrms: </td> <td align="left"><input type="text" name="Vrms" size="20" /></td> </tr> <tr> <td align="right">Z (Ohms): </td> <td align="left"><input type="text" name="Z" size="20" value="50" /></td> </tr> <tr> <td colspan="2" align="center"> <input type="button" value="Calculate" onclick= "calculate();" /> </td> </tr> <tr> <td align="right">dBm:</td> <td alig="left"><input type="text" name="dBm2" size="20" readonly="readonly" /></td> </tr> <tr> <td align="right">Vpp:</td> <td alig="left"> <input type="text" name="Vpp2" size="20" readonly="readonly" /></td> </tr> <tr> <td align="right">Vrms:</td> <td alig="left"> <input type="text" name="Vrms2" size="20" readonly="readonly" /></td> </tr> </table> </form> </body> </html> There is probably something simple that needs to be fixed but I have spent a whole day trying to figure this out. If anyone has any comments please let me know. Thanks in advance! When I click the button to open an url (example: http://www.yahoo.com) from a page, I can mark this url/screen name. So the next time I click on the same button, the same window will pop up instead of opening multiple windows. If I have already had the window opened not via the button, when clicking the button, it pops up a new window instead of opening up the existing. Is there a way to check the screen name or partial url of the existing window? If there is a match with the url being called from the button, it will use the existing one. |
