I am making a program that is for a test. it uses a combination of jsp and servlet and using tomcat 7.0 . My requirement is to identify whenever the user switches the tab or opens a new window of the browser, so that he is unable to use any other resources while giving the test. I am planning to start a thread that continuously checks the focus of the user. What is the possible solution ?

@Sudarshan_SMD the solution that the above question provides uses frameworks which I don't want to use – user3319299 Feb 17 '14 at 13:48

window.onblur works
<script>
window.onblur = function() {
//your code
};
</script>
jQuery implementations:
$(window).blur(function(e) {
// your code
});
