Hai....
In my online test website I am displaying all the questions in the same page one after another using the next button. I need to prevent the use of the back button and refresh button. How can it be possible on the same page?
Thanks...

Apply this script, it worked fine for me in all browsers

XML

<script type="text/javascript">
function noBack(){window.history.forward();}
noBack();
window.onload=noBack;
window.onpageshow=function(evt){if(evt.persisted)noBack();}
window.onunload=function(){void(0);}
</script>
