Hello,
I am not a js programmer, but i was hoping to find a prewritten script
that i may be able to use. all i need is a simple count up timer that
has a start, pause, and stop control to it, i have found some, but they
all seem to reset once you pause them, and i need it to stay where it
is at and then continue from the paused point once someone hits
restart.
if anyone knows where i can find something like this i would appreciate
it.
Thank you

If you want a counter that resonably accurately counts seconds, you
need to use a date object and run the counter every 50ms or so to grab
the system time and use that to count in roughly equal seconds.
If you just want a counter that runs about every 100ms or so and time
accuracy is not important, then the script below will do the job.
<script type="text/javascript">
var pageCounter = (function()
{
var counterLag = 100; // Milliseconds between updates
var counterValue = 0; // Initial value
var counterRef; // Reference to current timer
var textElement; // Element to displaying value
return {
// Initialise values and start the timer if one isn't
// running already. Don't zero the counter
start : function(id)
{
if (!document.getE lementById) return;
textElement = document.getEle mentById(id);
if (!textElement) return;
if (!counterRef) pageCounter.run ();
},
// Run the counter - uses setTimeout to call itself
// reasonably regularly and update the counter.
run : function()
{
textElement.inn erHTML = counterValue++;
counterRef = setTimeout('pag eCounter.run()' , counterLag);
},
// Stop the counter but don't zero the counter
stop : function()
{
if (counterRef) clearTimeout(co unterRef);
counterRef = null;
},
// Stop and zero the counter
clear : function()
{
if (counterRef) pageCounter.sto p();
counterValue = 0;
textElement.inn erHTML = counterValue;
}
}
})();
</script>
<button onclick="pageCo unter.start('xx ')">Start</button>
<button onclick="pageCo unter.stop()">S top</button>
<button onclick="pageCo unter.clear()"> Clear</button>
<br><span id="xx"></span>

yeah, i need to have something that is pretty accurate, i need it to be
within a second or 2 after a 3 minute period.
another question: if i were to use it as a countDOWN, would this be
more accurate?
once again, thank you.

Well, RobG's 'counterLag'- and my 'i'-variable are actually the number
of milliseconds between each value change. Setting it to 1000 would be
the best option to approach a real second (but you can't trust that you
will have an accurate second here).
another question: if i were to use it as a countDOWN, would this be
more accurate?
That would make no difference as it depends on the same timer mechanism
anyhow.

In *at least* some browsers, you can trust that you will not have an

I thank you to those that helped me, i have a better understanding now
of time counts on js and with what you have supplied i have solved the
problem.
Once again, thank you..

wow randy,
you need to get a life.. you have nothing better to do than to go
around and nitpick on "discussion forums" when someone asks a
question??
seriously, put down your mouse and your pocket protector, open up you
front door, you know, the big rectangle thing in the front of your
house, step through it and take a deep breath. then once you have
hopefully refreshed and realized that life is out there waiting for
you, you can come back here and not be such a sphincter muscle.
my 2 cents....
