Can I bring up a warning when the time is reached and click it to go to another screen?
<SCRIPT>
VaR lefttime = 3 // session time transfer
VaR tid

{
Lefttime --
Document. All. XX. innertext = "remaining:" + lefttime + "seconds"
If (lefttime = 0)
{
Window. clearinterval (TID );
If (window. Confirm ("do you want to enter? "))
Window. Open ("http://www.jb51.net /")
}
}
Tid = Window. setinterval ("X ()", 1000)
