Better timeout mechanism?

MattB · Aug 30, 2006

I'm using the old html method of creating timeouts for my asp.net (1.1)
pages. This apparently isn't working as well as I'd hoped because it
takes a postback to reset the timer. I've had complaints of people
typing into a dialog box and having the page time out while they were
typing.
Anyone got a trickier (javascript, I'd assume) way to set timeouts so
that a keystroke, or even a mouse movement resets the timer? Even if it
only worked with keystrokes and not mouse movement it would be an
improvement. LMK.

Thanks!

This is unedited production code, sort thru it and take what you want.

//in the form tag
<BODY onkeypress="window_activity()" onmousedown="window_activity()" ...

//in your javascript file
'the next few functions enable the timer which times out the user after
inactivity period
Sub StopTiming()
if timerPROMPT > 0 then
window.clearTimeout timerPROMPT
end if

sTime = Now
if msgbox ("Due to inactivity, your session is about to time out. Press OK
to remain connected, Cancel to end your session.",vbOkCancel,"Logout in
Progress") = 1 then
eTime = Now
elapsed = DateDiff("m",sTime,eTime)

'user had 2 minutes to respond
if elapsed > 2 then
document.all.SPREADSHEET_COMMAND.value = "CLOSE"
ClearRates()
else
window_activity()
end if
else
ClearRates()
document.all.SPREADSHEET_COMMAND.value = "CLOSE"
end if
End Sub
'monitor for user activity to determine when to time out the user
Sub window_activity()
if timerPROMPT > 0 then
window.clearTimeout(timerPROMPT)
end if

timerPROMPT = window.setTimeout("StopTiming()",1800000)
End Sub
