Accurate Stopwatch & Count-down Timer
Sep 16, 2006
I'm currently trying to make an accurate stopwatch and count-down timer. So far, I've just worked on the stopwatch, but it is inaccurate due to the calculation time of the Javascript. A more accurate method would perhaps be to compare the starting time and the current time, where the times are retrieved using the Date object. However, using this method I am not sure how to start/stop the timer (eg. I stop it at 1:00 and then start it again 5 minutes later, and it continues from the time it stopped - 1:01, 1:02, etc.). Code:

I have created a javascript count down timer to be used in asp.net. Basically, I create a countdown time for user to register (20 mins). If the countdown is around 5 min (that means the user is inactive for 15 min) then generate confirm box asking whether the session has to be active. If the user clicks ok, then we reset the time. If cancel is clicked, we proceed with the timer countdown till it reaches zero and logged out. IF he does not do any action, the countdown timer will proceed and logged out.
The problem is: Whenever the confirm box is popped up, the timer counter stops the counting. And If user does not click on either button and remain inactive for more than 5 min (by 5 min, the user should be logged out) there is nothing done that means, the counter stops countdown and the user is not logged out. Is there anywhere to determine in javascript whether a confirm box is popped up?

I am in need of a functionality for a system where in there PHP mysql system having a table bid which has columns(bid_product, "createtime")basically if the user does not bid for the product within 20 hours the bid will close for this i need to display a timer which keeps counting till 20 + hours of the create time, After a long search for timers i finally found a .Js which would work just fine for static values within the .js script when i tried to pass values from my database the timer does not change on itself but each time i have to refresh to check the time left.

I'm trying to make a countdown timer, it works fine if I define the value myself from where it has to start. However, when I try to take output from the user it says undefined and 'Nan'.Basically my problem is that if I give c a value like c = 30. it works fine. But when I try to take the input , it gives an undefined error.

I've been scouring google and multiple forums for an answer to this, and nothing really 'hit the nail on the head' as far as what I am trying to do.What I have is a game server status window in an iframe on my site, which is already set to auto refresh every 30 seconds. (It was a task in itself to get rid of the refresh flicker btw)Now, the problem is, people coming to the site don't know 'when' the 30 seconds started, even though it starts when they enter the site. This is causing confusion and many questions (even though they can just wait the 30 seconds and watch it change).
I found a forum on dynamicdrive that had a script which counted down, but the counter didn't reset to 30 seconds, which made it pretty much useless.All I want it to say is "next refresh in 30 seconds" under the iframe window, and count down.Beings as the php file that the iframe is linked to already starts timing itself upon page entry, I just need a timer that displays a countdown that also starts on page entry. I just want to show people that it will be refreshing when the timer hits "0".Is this possible? I've spent 4 hours trying different scripts and nothing does what I want (they either refreshed the entire page, or the timers wouldn't restart), so I am starting pretty much from scratch with this, and I am throwing this to the masters.

I'm trying to adapt a script I found online for a timer that goes in my webpage. The timer counts from 30 seconds down to 0. I've adapted it so that when it reaches 0 it goes back up to 30, but I was wondering how can I make it so that after a certain number of loops through the timer, it executes some other (non-JS) code instead of just doing the timer forever?I've introduced a variable t to try to do this, but when I put in if(t>1) {break} at the bottom, the timer doesn't work properly anymore (it doesn't display a number in the box).

As I am new to java scripts, I usually solve thing with trial and error. What I need is a very simple java script for a count down timer, after searching here I found this:
<font style="font-size:72px" color="#FF0000" face="Arial">
<script type = "text/javascript">
var page = "[URL]";
//The page to redirect to function getSeconds() {
startTimer (3); // 36 hours
} .....
I modified some stuff, as I defined the font face and size, the color as well, and I added a var to open a certain page when the time is over (as I said before, all these modifications came right with trial and error). So, is that script good? or are there better scripts that do the same job? Any script that does the same functionality of the script I mentioned but instead of showing digits it shows:
01 minutes 31 seconds

Im looking for a js stopwatch that would express a figure input by the end user -
so for example the code could ask 'how many calories do you burn an hour' - user inputs 100
They start the stop watch and the stop watch show both the seconds/minutes increasing, but also show the calories increasing as (input="100"/60)/60

I am having trouble with my formulas for my salmon calculator. When I select seafoodgrill from the pull down menu and then enter 10.99 per lb, 85 % yield, and 25.50 price I get a 23% food cost. That is not correct. The correct answer should be around 24.6%. How have I set up the formula wrong. Code:

I've been using pop-ups for some time now and I still can't figure out how to get the image to fit perfectly in the new window. There's always a few pixels of background showing and I have to increase the size of the window just to have the spaces around the image to even out. Is there any way to completely remove the vertical and horizontal spaces in pop-ups?

I have a page that has a total field that will have a value when the page is loaded. I also have a few select options that modify the total via an onchange event. Problem is, when i change a select option twice, I cant work out how to get the correct total happening instead of just adding more to the total. I'll show you what I mean.. Code:

Okay, reason I say that is, its not accurate to the actual domain that the "script" is located on.
For example, domain.com has the <script url=domain2.com/jsfile> which has " document.domain " (this = domain.com)
However, if i have frame of domain3.com which frames domain.com the domain will show domain3.com but thats not what I care about, I want domain.com since thats whats actually being shown.

[Code]....
No matter if I set min/max, step, etc....when sliding all the way left or right, the values are incorrect at the end. For example, with default values, sliding all the way left results in a value of 10....but moving back to the right slightly causes it to drop to 0 and then count up from there. The reverse is true for the right/high end. It's behaving this way in both IE7 and FF 3 on XP. [URL]

I am trying to refresh a page at a 30 second interval with a function called timeout(). I tested my code with a message, and it worked fine. When I replaced it with a php script to refresh the page, nothing happened. I was not sure if this question belongs here or under the php forums. I thought I'd try here first. What am I doing wrong? Is there a better way to do this? Code:

Any suggestions on code, or reference material for this?
