Hello i am having an a web page on which conducts online exam.I have used the following javascript for creating a time exam count down time




Now my problem here is that when i click refresh button the timer resets itself and that is WRONG because that will give the users extra time to finsh the exam paper.
I googled and all they were suggesting me is to handle it using session rather then disabling.
Any suggestions please ?

Luckily, you can't. Please read InterfaceDesignersRule1. You shouldn't be trying to stick your fingers where they don't belong.

Keep track of the timer in the session as you've already discovered.

Come on, it's not that hard. Whatever generates that page will also put the current time into the session. That's the basis for your timer. If you need to notify the user immediately when the timer expires, you can send an AJAX request every second which compares the current time to the time in the session and see if it's expired.
