hi,

PHP Code: <script language="JavaScript"> TargetDate = 24 * 60 * 60 * 1000; ForeColor = "navy"; CountActive = true; CountStepper = -1; LeadingZero = true; DisplayFormat = "%%H%% Hours, %%M%% Minutes, %%S%% Seconds."; FinishMessage = "It is finally here!"; </script> <script language="JavaScript" src="http://scripts.hashemian.com/js/countdown.js"></script> Hi, I want to restrict opening my popup window if it is already opened. For simple scenario, it is quite possible to do but in my case -- 1) When parent page is opening popup window, it is getting refreshed (required from client for some reason). 2) Once submit button is clicked from popup window, again parent page is getting refreshed (again its a requirement from client side). With these 2 conditions, I lost my saved value from variable and hence new popup is keep coming when the action is same. Currently I am using below code to open popup [CODE] function OpenWindow() { if(winPop && !winPop.closed) { alert("Popup is already open"); } else { winPop = window.open('MyPopupPage.aspx'); } } [CODE] Please help me to get rid of this problem. Thanks in advance. - Bhasker Hello, I understand that this question have been posted before several times. I looked at many of those threads and tried it but could not get it to work. So the idea is to use either cookies or html5 localstorage to control the java script behavior, but how do I really implement it on my code? Please help me out here on piecing all the code together. Either cookie/localstorage is fine. Thanks in advance Code: <div id='cptup-ready'> </div> <script data-cfasync='false' type='text/javascript'> //<![CDATA[ window.captain = {up: function(fn) { captain.topics.push(fn) }, topics: []}; // Add your settings he captain.up({ api_key: 'XXXXXXXX' }); //]]> </script><script data-cfasync='false' type='text/javascript'> //<![CDATA[ setTimeout(function() { var cpt = document.createElement('script'); cpt.type = 'text/javascript'; cpt.async = true; cpt.src = 'http' + (location.protocol == 'https:' ? 's' : '') + '://captainup.com/assets/embed.en.js'; (document.getElementsByTagName('head')[0] || document.getElementsByTagName('body')[0]).appendChild(cpt); }, 31000)(); //]]> </script> I am wanting to display an image for 24 hours, how can I do this?
Hi guys, I've looked around the web and tried to find a Javascript Countdown, however, the only ones I could really find were the ones that countdown to a particular date (see below). Code: <script language="JavaScript"> TargetDate = "12/31/2020 5:00 AM"; BackColor = "palegreen"; ForeColor = "navy"; CountActive = true; CountStepper = -1; LeadingZero = true; DisplayFormat = "%%D%% Days, %%H%% Hours, %%M%% Minutes, %%S%% Seconds."; FinishMessage = "It is finally here!"; </script> <script language="JavaScript" src="/js/countdown.js"></script> Problem is, it counts down to a particular date, and I don't want that. The reason why is because everyone's time will be different, and I want it to be a "global" countdown, fr an event happening on a website (like the launch of something). Is it possible to, other then going by date, go by days/hours/minutes/seconds? So if I enter say, 2 days, 5 hours, 0 minutes, 0 seconds, it'll start counting down EXACTLY 2 days and 5 hours, and not change per people's time zone? Any help would be greatly appreciated. If someone can point me in the right direction, or has a code already developed, I'd really appreciate it.. Thank you so much! hi guys, as im still a noob at javascript, so im asking for your help, i didnt make this script, someone else did and i asked for their permission to change it to my needs, the problem is, i have it working for times that are over an hour long, but i need to also make it possible to display in just under an hour aswell, eg instead of 01:00:00 it would display 60:00 then 59:59 eg, so basically im asking, how can i take the hours out of this, without it currupting the entire JS? Code: var HAS_EXPIRED = 'Time has Expired!'; var IS_NONE = 'None'; function secondCountdown(s){ if(s){ var timeleft = document.getElementById('timeleft').innerHTML; if((timeleft == HAS_EXPIRED) || (timeleft == IS_NONE)) return false; timeleft = timeleft.replace('<font>', ''); timeleft = timeleft.replace('</font>', ''); var time = timeleft.split(":"); var secs = time[2] * 1; var mins = time[1] * 1; var hrs = time[0] * 1; secs += (mins * 60) + (hrs * 3600); secs -= 1; if(secs <= 0){ document.getElementById('timeleft').innerHTML = HAS_EXPIRED; return false; } else { hrs = Math.floor(secs/3600); secs -= (hrs * 3600); mins = Math.floor(secs/60); secs -= (mins * 60); if(hrs < 10) hrs = '0' + hrs; if(mins < 10) mins = '0' + mins; if(secs < 10) secs = '0' + secs; document.getElementById('timeleft').innerHTML = hrs + ':' + mins + ':' + secs; } } setTimeout('secondCountdown(true)',1000); } bootloaderAdd('secondCountdown()'); bootloaderOn(); Cheers. Dan I have the below form where the user enters the hours and minutes worked on a task. I want to be sure that the total for the form is at least 8 hours. How can I do that? Code: <form method="POST" onSubmit="return validateHours()" name="theForm" > <p>Hours<input type="text" name="hours[]" size="20">Minutes<input type="text" name="minutes[]" size="20"></p> <p>Hours<input type="text" name="hours[]" size="20">Minutes<input type="text" name="minutes[]" size="20"></p> <p>Hours<input type="text" name="hours[]" size="20">Minutes<input type="text" name="minutes[]" size="20"></p> <p>Hours<input type="text" name="hours[]" size="20">Minutes<input type="text" name="minutes[]" size="20"></p> <p><input type="submit" value="Submit" name="B1"><input type="reset" value="Reset" name="B2"></p> </form> Hey everyone. I need a little help and I'm not an expert by any stretch of the imagination with javascript. I have a simple little code script and I'd like either the onClick function (or the entire code itself, whichever is easiest) to only load once every 24 hours for each IP address. So "123.1.22.333" should only get the effect of this code once every 24 hours regardless if they revisit my site 5 times a day let's say. So here's my little script: Code: <script language="JavaScript"> function goNewWin() { TheNewWin=window.open("http://google.com",'Google','toolbar=0,location=0,directories=0,status=0,menubar=0,scrollbars=1,resizable=1'); TheNewWin.blur(); } </script> <body onClick="goNewWin()"> Any help would be very appreciated.

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've done LOTS of Googling on this subject. I can write cookies beautifully to '[other data]; path=/Stats' but I can't figure out how on EARTH to read from it. How do I access the data there? If I just say path=/ then it will read beautifully, but I need to be able to have different paths for what I want this to ultimately do.
Hello, I've been trying to figure this script out for awhile and I've hit a wall. Basically, what I want to do for my organization's website is to use JS to display an image containing our hours and have it change each day of the week. The hard part (for me) is that there are certain days we're closed. Ideally, I'd like a separate "We're Closed" message to overwrite the image carrying our hours on specific days (major holidays like Xmas, New Years, Vet's Day, furlough periods, etc. etc.). Here's the code I've managed to cobble together (I have a real basic understanding of JS, so I've been pulling scripts from sites offering free copy/pastecode): [CODE] <script language="javascript"> mytime=new Date(); mymonth=mytime.getMonth()+1; mydate=mytime.getDate(); myday=mytime.getDay(); arday = new Array("sunday.png", "monday.png", "tuesday.png", "wednesday.png", "thursday.png", "friday.png", "saturday.png"); document.write("<img src='" + arday[myday] + "'>"); if (mymonth==12 && mydate==24){document.write("<img src='closure.png'>"); } </script> [CODE] For the most part, this code works just fine. However, if I jump my system clock to December 24, the "closure.png" comes up appears ALONGSIDE the hours image for that day of the week. In other words, I've got two images appearing right next to each other - that's not what I want. How can I work the code in such a way that when a closure date comes up (in this case, 12/24), just the "closure.png" image shows up by itself? Thank you all so much for your time and patience. hi, I've got a problem and i really need help. this is my code <script> var y= new Date(); y.getFullYear() + '<br />'; alert(y); var year = new Date(); year.setFullYear(prompt('Enter the year','1990'),prompt('Enter the month','1'), prompt('Enter the day','1')); alert(year); var yy = y-year; alert(yy); </script> i want when a user write his/her birthday JS calculate the age. that's all Hello. I wonder is there any javascript to calculate IP length For example I have Start ADDR: VLAN_ADDR which is: 10.52.28.0 Stop ADDR: VLAN_LAST which is 10.52.29.254 As I know:result is 512 or another example: Start ADDR: VLAN_ADDR which is: 10.52.64.11 Stop ADDR: VLAN_LAST which is 10.52.64.15 As I know:result is 5 How to count it in javascript code ? Results are "numbers" Best regards Leos. Hi there, I'm new here in this forum and I've registered to ask a question about JavaScript or Jquery. I don't know which to use. I have my code php like that: <?php //Get the data from system and return in EU format function ShowDate() { $Date = date("d"."/"."m"."/"."Y"); return $Date; } //Get the time from system function ShowTime() { $Time = date("H".":"."i"); return $Time; } ?> Now I have two input box <html> <head> </head> <body> Type the date:<input name="txtdate" type="text" class="input" id="txtdate" title="e.g dd/mm/yyyy" value="<?php echo ShowDate(); ?>" size="9" maxlength="10"> <br> Type the time:<input name="txttime" type="text" id="txttime" value="<?php echo ShowTime(); ?>" size="5" maxlength="5"> <br> London: Friday May 21 2010 05:12:00 <br> New York: Friday May 21 2010 00:12:00<br> Hong Kong: Friday May 21 2010 12:12:00<br> Tokyo: Friday May 21 2010 13:12:00<br> </body> </html> So.... the important is the user can interactive with the date. If I change the date or time all this values will be change as well. Someone knows how can I do this? The field txtdate I will get from a calendar plugin (javascript) that I already put in my code.
