I am doing an online quiz application in PHP. I want to restrict the user from going back in an exam.

I have tried the following script, but it stops my timer.

    Try it with ease :

    history.pushState(null, null, document.title);
    window.addEventListener('popstate', function () {
        history.pushState(null, null, document.title);
    });
