how to retain the page time upon page refresh?

Question

i m designing a on line exam in jsp.a count down timer starts upon exam starting.The maximum time to answer a question is 1 min.but as 2nd question comes upon page submit the timer again starts from the first.so how i solve the problem.

Answer 1

The approach is

If you have 10 questions, that means 10 mins. So the time has nothing to do by itself, it goes with active question. When the question changes, so the clock resets. Creating count down from 59sec to 00sec is easy job. Here you have to use SetInterval or SetTimeout functionality at the client side for showing the time remaining. These function you have to code until they are reached 00 sec and call this function again when the question changes. So the clock begins.

I have just mentioned any overlay of the process, but it can be done without problems. Give a try. You will succeed

Hope this helps

2 ways immediately spring to mind

1 is to store the time in a local variable and work with that so the page refresh shows the value of the variable

the other is to base the time on the local system time of the user - so store the time that the exam is started and keep displaying the current time minus the stored start time
