I've seen a lot of question on this and the solution seems to be
window.onbeforeunload
But i've tried it, seems to work great to warn the user before the pages unload, but there is no way i've seems to be able to set the message in the message box.
i've tried this :
window.onbeforeunload = function (){ return "test";}
But I've got the default message of the browser.
I'm using the french version of firefox 8.0
Thanks all
Firefox does not allow you to change the message, but webkit (Chrome/Safari) does. In webkit, if you return a string, in your onbeforeunload handler, it will interpret that as "pop a warning dialog" with your string as the message.
Sadly onbeforeunload is quite raw and not that great. Hopefully browsers figure out a better way to do this in the near future.

I'm wondering if can I change the window.beforeunload message. All examples on the internet are similar to this:
$(window).bind('beforeunload', function() {
return 'You have unsaved changes. If you leave the page these changes will be lost.';
});
That's cool, and in Google Chrome my message will be displayed, but in Firefox the default message is displayed. How can i trick Firefox to display my message and not the default message?
onbeforeunload is a weird event. Browsers have been debating what to do with it for a while.
IE and Chrome will display your message in the dialog along with their own message.
Firefox used to display your message, but in version 4+, they stopped supporting custom messages. See this: https://bugzilla.mozilla.org/show_bug.cgi?id=588292
Opera doesn't even support the onbeforeunload method!
This method is under debate because it can be used for evil, and also because it can confuse/annoy users. Scammy, virus-laden sites can use messages like:
"Leaving the page will mean your computer may still be infected, please stay and install our virus scanner"
Nowadays, websites can use AJAX / localStorage to save changes, so this event isn't really needed.
unload function in jQuery works fine in Firefox but not in chrome and safari. please check this fiddle in chrome and Firefox. http://jsfiddle.net/jeevankk/Gywnw/2/ . Alerts a message when the page is refreshed.
$(window).unload(function() {
alert("Unload");
});
This should work to show a confirmation when the users leaves, this is also not part of any standard.
$(window).on('beforeunload ',function() {
return 'Are you sure ?';
});
I found Joseph's comment as the correct answer, So posting this answer.
Dialogs are blocked/prevented during "beforeunload" (with exception to the beforeunload prompt) and "unload" events. Can be confirmed by checking your console.
This is because the unload event is not part of any standard
https://developer.mozilla.org/en/DOM/window.onunload
check the bottom of the page i just linked to.
jQuery's unload works well in chrome too, with the exception that Chrome doesn't allow alerts within it. I've used it to set cookies. And if it works with Chrome hope it works in Safari too.
the unload function of jquery has some problem with browsers..refer the following link
http://bugs.jquery.com/ticket/5538
can you elaborate on the problem so that we can find some work around??
you can use onfocusout on the body .. but i wouldn't recommend if you are trying to use something like an alert, on this operation, asking the user not to leave your page ..
"refresh" action in the Firefox does not fire the unload event.
We should use onbeforeunload instead.
Confirm with Firefox version 47, Mac OS X
I am using asp.net 2.0 with c#.
i want a pop up to be displayed when user tries to close the browser and if user click on "no" [i.e. he don't want browser to be closed] then it prevent browser to get closed.
Please help.
Thanks
the code they use is
window.onbeforeunload=function() {
if (somereasonorother) return "You did not save your stuff"
}
Pointy, this is entirely possible, and it's done by many web pages for perfectly reasonable reasons.
Try something like this:
function areYouSure() {
return "Are you sure you want to leave this page?";
}
window.onbeforeunload = areYouSure;
You can try to attach yourself to the onbeforeunload event:
<body onbeforeunload="ConfirmClose();">
But I have to mention that it won't work on all browsers. The only ones that prompted something after I closed a window were Chrome, Firefox and Internet Explorer; Opera ignored the code in the JavaScript method.
This is mostly because some browsers trigger the onbeforeunload event only when you're trying to leave the current page by visiting another one, and not when you close the current window / tab.
how to close a browser window within given time using javascript also without the warning message in IE and Firefox
I agree with the other guys. without looking too hard, I'd say you're out of luck closing a window in javascript without getting a warning message.
Any javascript you write will be executed by the browser. If that browser decides to trap a window.close() piece of script, then that's what it's going to do. You're constrained by the boundaries the browser places on you.
Warining message is browser-dependent and you cant omit that. As far as I remember, you need to open window with script to have rights to close it.
You can only close a window (with no user warning) that was previously opened with a script.
You can't, the warning message is designed to stop code from disruptively closing windows.
Use setTimeout to manage when to run your window.close() script.
EDIT : For warning message, I don't know the solution.
For the warning message, I know StackOverflow uses the onbeforeunload event. If you override that event (not just attach a handler) with a function that returns false, it'll probably get rid of the warning. For example:
window.onbeforeunload = function(){return false;};
setTimeout(function(){window.close();}, 10000); // close after 10 seconds
Just as a general principle, web browser windows belong to the user, not to you. If you are looking to create, destroy, or resize them, you are doing something wrong.

Only works in IE:
window.setTimeout(function() {
window.opener='x';
window.close();
}, 10000);
It seems like you can do it (though you shouldn't). Check this question
Javascript to close IE6, IE7, IE8 and Firefox without confirmation box?
Two years ago I had a need to trap the closing of a web browser as a javascript event for a web app. At the time I found there was no way doing this that worked for all browsers. IE had an event that I could used, but it was IE specific. I looked into other work arounds, like a heart beat sort of ping to the server, but I didn't like any of them at the time.
Is there anyway currently to trap the closing of a web browser now? Thanks!
You can use the
window.onbeforeunload
javascript event to do this, though this will trap more than just closing the browser. This event will also get fired each time someone tries to navigate to another page, refresh the current page, etc. It's handy if you're trying to do something like warn people of unsaved changes before they leave the current page.
onunload works in IE and Firefox.
