Could anyone help me to solve the problem that exists in my code.
If the user inputs the command exceeding the time limit, say for example, 7 seconds, the system will deduct his/her marks.

Yet, my code shows that if the user can input within the limit also deduct mark .
I hope someone can help me.

My code is at here.

If the user inputs what command?

if the user presses the "submit" button beyond the time limit, then marks will be deducted, otherwise, marks will be unchanged!! :)

Yes but there are 4 submit buttons. Do they have to click all 4 within the alloted time or just one?

Also, I notice that the random numbers keep getting generated. Should this stop happening once the user submits? If so, after any submit, or after all 4 submits?

Is this a game? If so please explain the rules and basic strategy in a bit more detail. If it's something else, please explain its purpose.

Sorry for replying so late.

Yes, this is a game.
1) The restaurant has 4 table and there is a waiter taking charging of assigning people to ONE of the tables ( max ppl in a table = 12).
2) If the customer is not be served within 5 SECONDS, he gets angry and goes away. Marks will be deducted.
3) After the customer is assigned to one of the tables in the restaurant, he will dine. Finally, the group of customers leave after 10 seconds. So the vacancy for that table increase.

My problem is even i put the customer to a table within time limit, mark is deducted as well.

I'll assume for now you don't want me to write this for you. I'm not sure if I want to.

I can tell you that in the code from your post there is no limit on the number of diners per table, the time limit is 7 seconds for seating and there's no time limit on how long the diners remain at a given table.

Furthermore the problem with the 7 second timer is two or maybe threefold. The first issue is that in this construct:



if (setTimeout('randomNumber()',7000)){
total=total-1;

the highlighted always sets the timeout and almost always will evaluate as true. The setTimeout() function returns an object (the handle for the timeout), which is always true. Sometimes in a case like this it can be interpreted as a number though, also always true unless it happens to be 0, which it sometimes can be.

The timeout's handle is not stored as a reference in a variable or elsewhere, so cannot be canceled once set in motion.

And it's repeatedly invoked. Once when Start is pressed, again each time one of the submit buttons are pressed. These timeouts all run at once, so at some point you can have one firing off its function (the randomNumber() function) every second or so or even more frequently, most likely in an erratic pattern.

Before I read your latest post, I assumed this was a game and was playing around with it. I arrived at:

The rules are different than yours, but it illustrates getting a handle on the timeout and clearing it if the player responds in time.

The rules for this game are - You are allowed 4 shots at each table, if you dawdle at any point for 7 seconds you lose a point. Once you have completed all four shots at all four tables, the game is over.
