how to block the value of a variable?

Hi,

I want to show pictures each 5 seconds, so i define first the present time:

tempsreel= new Date()
trh=tempsreel.getHours()
trm=tempsreel.getMinutes()
trs=tempsreel.getSeconds()
te=parseInt(trh)*3600+parseInt(trm)*60+parseInt(tr s)

Now i calculate 5 seconds further:
nte=te+5

Finally, the new picture must appear five seconds later, but i can't compare
"te" with "nte" because the difference will always be 5. What i want is to
block the value of "nte", so when the real time equals "nte", then next
picture ...

Any idea how?
Thanks
Chris

How about utilizing the timer functions setInterval or setTimeout. It seems
setInterval is precisley what you need.

For example: you define the function that displays the picture
function show_my_cool_pic(){
// do some magik here
}

// And then start a timer that calls the function periodically

timer_id = setInterval("show_my_cool_pic()",5000); //5000 is 5 seconds as
milliseconds.


Now the function show_my_cool_pic() should be called each five seconds.
If you ever want to stop it, then call

clearInterval(timer_id);
