How to make this working?

Code:

$(window).unload(function() {
confirm("Exit confirm");
if(confirm == ok) {
window.close;
}else{
return false;
});

Oh, how can I explain this..

Okay, ehem. Actually, JQuery IS Javascript. You can mix them no problem at all really, and really that's not a different language. JQuery is a language that created using Javascript so yes you can use Javascript inside Jquery as long as the syntax is legal to use. See more here : http://w3schools.invisionzone.com/index.php?showtopic=46447

Ahem. Where are you using this code? In your forum? Or anywhere else?

Ah, perfect. I won't open the site because I've really hate W3Schools but that's what I'm currently looking for. Thanks. And I'll use that at my forum, my web server too.

Do you have jQuery installed on your forum / website?

if you want my script, here's mine it does the same for your script

Code:

$(function() {
$(window).unload(function() {
e.preventDefault();
confirm('testing confirm');
if(confirm == yes) {
window.close;
}else{
return false;
}
});

that's mine it looks like your script like ? well i just edited your script, am i allowed to copy your script and apply them into my website ?

Nope, nope. If you do that way, then the JavaScript will search for the variable named 'e'. You can just do something like

Code:

$(function() {
$(window).unload(function() {
event.preventDefault();
confirm('Lorem ipsum dolor sit amet. Click OK if you agreed.');
if(confirm == 'OK') {
window.close;
}else{
return false;
}
});
});

Remember; don't do some syntax error. You'll forget to close the 'window unload' and the 'document.ready' command. It will results some syntax error.

Code:

$(function() {
$(window).unload(function() {
//stuffs here, in this example I just do some alert
alert('Bye now!');
});
});

we can do something with onbeforeUnload that are written here

Code:

window.onbeforeunload = function(e) {
return 'are you sure ? your data will be lost !'
};

Don't forget to use the parameter e

Code:

window.onbeforeunload = function(e) {
 e.preventDefault();
 confirm('Are you sure?');
 if(confirm == ok) {
  window.close
 }
};
