I have a customize pop up box like a lightbox or a modal box and I want to show it and prevent the page from unloading or exit when a user tries to leave or exit the page so heres my code and my try so far:
$(window).bind('beforeunload', function(){
return loadPopup();
});
As you can see from the above codes, when a user tries to exit or leave the page, it should execute a function:
loadPopup();
But it does not work, the loadPopup(); doesn't fired. What supposed to be a problem on my above codes why it doesnt execute the loadPopup(); function?
VeeKayBee solution is correct.
Anyway you can do this with JQuery too:
$(window).bind('beforeunload', function(){
fireOnLeave();
return '';
});
function fireOnLeave(){
console.log('Fired');
}
You can check the console log and see 'Fired' string which is confirming that the function has been fired.But you have to return a string to 'beforeunload' event.
And also jquery .unload do the thing but it has been deprecated since JQuery 1.8

Check this http://jsfiddle.net/Cnsyd/
I am not sure you do something using jQuery, but obviously you can do something with javaScript.
function closeIt()
{
return "Any string value here forces a dialog box to \n" +
"appear before closing the window.";
}
window.onbeforeunload = closeIt;
JavaScript onbeforeunload event. It's introduced by Microsoft, but works in most browsers and click here for more details.
Believes this is the thing ultimately you requires.

I have the following function, if I use the alert dialog the Click section (1) is reached. if I remove the alert dialog the page is posted and the Click section (1) is never reacted. How can I i solve it?
$("#txtInput").change(function () {
alert('...');
$("#btn.ClientID").click(); // Click (1)
});
If you want the change event to call JavaScript function before posting back to the server. Then pass an event object into the function and then use preventDefault(). This stops the default behaviour.
$("#txtInput").change(function (e) {
e.preventDefault();
$("#btn.ClientID").click(); // Click (1) - It's unlikely "btn.ClientID" is the correct name of your button
});
From out of curiosity can i Control window.onbeforeunload event like check if the user decided to leave the page or stay in it and can I raise an alert or some function based on his decision if yes please tell me
<script type="text/javascript">
$(window).bind("beforeunload",function(){
if(//stay on page)
alert("i want to stay on the page");
else //leave page
alert("i want to leave the page");
});
</script>
I understand that window.onbeforeunload is an event that give the user a message to tell him that maybe you forget to do something before you leave but this quest is just out of curiosity and thank you
You can ONLY return a string which will show a dialog confirmation displaying the string you returned (But with additional ok/cancel buttons to confirm the action).
<script type="text/javascript">
$(window).bind("beforeunload",function(){
return 'Are you sure you want to leave this page?';
});
</script>
You cannot get the result of onbeforeunload. Also, even if you somehow managed to figure out a way to get the result, you wouldn't be able to raise an alert. You could probably run another function.
The showModalDialog(), alert(), confirm() and prompt() methods are now allowed to do nothing during pagehide, beforeunload and unload events.
Put a timer of one second. Clear it on unload. Should work, but didn't test it.
window.addEventListener('beforeunload', function (event) {
var timeId = setTimeout(yourFunctionIfTheUserStays, 1000);
window.addEventListener('unload', function (event) {
clearTimeout(timeId);
})
return 'Are you sure you want to leave this page?';
});
I am popping up a dialog box when someone tries to navigate away from a particular page without having saved their work. I use Javascript's onbeforeunload event, works great.
Now I want to run some Javascript code when the user clicks "Cancel" on the dialog that comes up (saying they don't want to navigate away from the page).
Is this possible? I'm using jQuery as well, so is there maybe an event like beforeunloadcancel I can bind to?
UPDATE: The idea is to actually save and direct users to a different webpage if they chose cancel
You can do it like this:
$(function() {
$(window).bind('beforeunload', function() {
setTimeout(function() {
setTimeout(function() {
$(document.body).css('background-color', 'red');
}, 1000);
},1);
return 'are you sure';
});
});
The code within the first setTimeout method has a delay of 1ms. This is just to add the function into the UI queue. Since setTimeout runs asynchronously the Javascript interpreter will continue by directly calling the return statement, which in turn triggers the browsers modal dialog. This will block the UI queue and the code from the first setTimeout is not executed, until the modal is closed. If the user pressed cancel, it will trigger another setTimeout which fires in about one second. If the user confirmed with ok, the user will redirect and the second setTimeout is never fired.

I know this question is old now, but in case anyone is still having issues with this, I have found a solution that seems to work for me,
Basically the unload event is fired after the beforeunload event. We can use this to cancel a timeout created in the beforeunload event, modifying jAndy's answer:
$(function() {
var beforeUnloadTimeout = 0 ;
$(window).bind('beforeunload', function() {
console.log('beforeunload');
beforeUnloadTimeout = setTimeout(function() {
console.log('settimeout function');
$(document.body).css('background-color', 'red');
},500);
return 'are you sure';
});
$(window).bind('unload', function() {
console.log('unload');
if(typeof beforeUnloadTimeout !=='undefined' && beforeUnloadTimeout != 0)
clearTimeout(beforeUnloadTimeout);
});
});
EDIT: jsfiddle here
Not possible. Maybe someone will prove me wrong... What code do you want to run? Do you want to auto-save when they click cancel? That sounds counter-intuitive. If you don't already auto-save, I think it makes little sense to auto-save when they hit "Cancel". Maybe you could highlight the save button in your onbeforeunload handler so the user sees what they need to do before navigating away.
I didn't think it was possible, but just tried this idea and it works (although it is some what of a hack and may not work the same in all browsers):
window.onbeforeunload = function () {
$('body').mousemove(checkunload);
return "Sure thing";
};
function checkunload() {
$('body').unbind("mousemove");
//ADD CODE TO RUN IF CANCEL WAS CLICKED
}
Another variation
The first setTimeout waits for the user to respond to the browser's Leave/Cancel popup. The second setTimeout waits 1 second, and then CancelSelected is only called if the user cancels. Otherwise the page is unloaded and the setTimeout is lost.
window.onbeforeunload = function(e) {
e.returnValue = "message to user";
setTimeout(function () { setTimeout(CancelSelected, 1000); }, 100);
}
function CancelSelected() {
alert("User selected stay/cancel");
}
window.onbeforeunload = function() {
if (confirm('Do you want to navigate away from this page?')) {
alert('Saving work...(OK clicked)')
} else {
alert('Saving work...(canceled clicked)')
return false
}
}
with this code also if user clicks on 'Cancel' in IE8 the default navigation dialog will appear.
I'm trying to setup an exit survey so that when a user leaves our checkout page they are prompted asking them why they're leaving.
Is this possible?
I've spent some time on Google but it appears as though the only solution is a simple browser-controlled confirm-like prompt. Is this true?
update
The following confirm dialog never appears, the page just changes or exits. How can I prevent the page from changing/exiting until I wait for a user's response. I guess I should ask, how can I resume a user's exit/page change action after using e.preventDefault(); ?
jQuery(window).bind('beforeunload', function() {
return function () {
alert('x');
setTimeout(50000, function () {
confirm('you sure?');
});
}();
});
If you are using jQuery you can just do
$(window).unload( function() {
//statements
});
You can do anything you want in the onunload event of the browser:
body.onunload = function() {
foo();
bar();
}
As suggested by levu, use the onunload event in combination with a custom modal dialog, such as thickbox - http://jquery.com/demo/thickbox/
I have a page with a form that is submittes via ajaxSubmit() (so, without changing the page).
My goal is that, when the user try to change page (or even to close the browser), i ask him if really want to exit the page without sending the form (exactly as gmail does).
Gmail for example do this with a window.confirm-like popup, but if it is possible, i'll like to handle it with custom messages and options.
jQuery have the unload event:
$(window).unload( function () { alert("Bye now!"); } );
but it permits me just to do something before exit the page; i need to 'block' the page exit, if the user click the relative button.
So, how to handle (and cancel) the page-exit event?
try the following. Demo here
<script type="text/javascript">
function unloadPage(){
return "dont leave me this way";
}
window.onbeforeunload = unloadPage;
</script>
It's possible bind the "onbeforeunload" event with jQuery:
$(window).bind('beforeunload', function(e) {
return "ATTENZIONE!!";
});
It works!!
