You can use onbeforeunload where supported, but use wisely. Note that it will also fire when going back/forward or reloading.

hello sir,
i use onbeforeunload function, its working fine, it can control the browser
close only, but i need to control Alt + F4 also . If i use Alt + F4 to close means the browser should be closed, please give me the coding and some idea.

So you don't want the onbeforeunload to fire when Alt-F4 is pressed?

[mageswar005]

i need to fire when Alt-F4 is pressed , and also my coding is not working in mozilla firefox i dont know why? my coding is below

[CODE=JS]
window.onbefore unload=function (){
if (window.event.c lientY < 0 && (window.event.c lientX > (document.docum entElement.clie ntWidth - 5) || window.event.cl ientX < 15) || window.event.ke ycode==115 ) {
if(sessid) {
event.returnVal ue="This will end your session.";
}

}
}

function closeme(sessid) {
if (window.event.c lientY < 0 && (window.event.c lientX > (document.docum entElement.clie ntWidth - 5) || window.event.cl ientX < 15) ||window.event. keycode==115 ) {
if(sessid) {
window.open ("logout.php ,
"mywindow","wid th=2,height=2") ;
}
}
}
[/CODE]

The code is very IE-specific which is why it won't work in other browsers. To use onbeforeunload where supported, use return:

window.onbeforeunload = function() {
    return "some text";
}

window.event is IE syntax; for other browsers, use the event passed as a parameter to the function. Finally, the clientX/Y < 0 hack works only in IE.

I'm not sure if you mean the problem is solved or you still want a solution.

Anyway, if it's the latter, my question was quite valid. If you tell us why you want to detect the browser close event, then we may be able to provide an alternative solution. For example, if it's because you want to log out if the user closes the browser, you could use a session timeout instead.

Hello sir,
In My Application online Test Modules should be conducted, at that time some student didnt take test and simply close the browser,so we didnt track the marks for that student.Can you please give me the solution for this.

You can use a timer server-side by setting the time when the test begins. Any answers submitted after the time has elapsed is not counted. So if the student closes the browser and then reopens, it wouldn't make a difference. If they try to restart the test, it will continue from where they left off. If it's after the time has elapsed, they can't continue. No JavaScript required except to show the time remaining.
