I want to set a cookie when a visitor on the page closes the browser.
I used onbeforeunload method like this
<script language="JavaScript" type="text/javascript">
window.onbeforeunload = confirmExit;
function confirmExit()
{
return "You have attempted to leave this page. If you have made any changes to the fields without clicking the Save button, your changes will be lost. Are you sure you want to exit this page?";
}
</script>
followed this link
But found out that even refresh of page or click on any hyper link on the page,pops up an alert.
I need to set cookie only when visitor clicks cross button of browser and not on page refresh.
I followed some of the links like the one above and another here. And found from the post that we can not differentiate between close and refresh. But those posts were 3-4 years back.
Is there is any way to differentiate these events using JavaScript or Jquery?
I'm afraid you have no way to tell.
The only thing you can do is overload clicks on links and set a flag. But you can never know if it is a refresh or a close...
Hmm, what about this:
Set a cookie onbeforeunload
Globally onload, check the timestamp of the cookie to see whether this was a link, or a new session
If the timestamp difference is only a few seconds, delete the cookie
Well, unload is called when browser is closed and onload is called when you try to reload. You can use these properties and set flags , and fire events accordingly
Browser close and reload Check this link for more details

I'm building a text editor in my website, the workflow is as follows.
In /list, the user picks an entry they want to edit from a list which takes them to /edit/[article_id].
The user does their work, and then clicks submit.
The server processes the thing, and redirects them back to /edit/[article_id] which by now reflects the edited work. The server also activates a flash message on the page to indicate the edit was successful.
By this point, the user probably wants to go back to /list and clicks the browser's Back button. This will take them back to the editor repeatedly depending on how many times they submitted.
I've tried putting a Back button somewhere on the page, but a good many users simply ignore it.
I'd rather not make the submission posted via AJAX, since that would also affect the flash message system.
What I like to do, is replace the last entry on the history list when the user submits, without changing its length. Is it possible?
Try this
window.location.replace(url);
after using replace() the current page will not be saved in session history, meaning the user won't be able to use the Back button to navigate to it.
Use window.close():
close();
Note: the current tab is implied. This is equivalent:
window.close();
or you can specify a different window.
So:
function close_window() {
if (confirm("Close Window?")) {
close();
}
}
with HTML:
close
or:
close
You return false here to prevent the default behavior for the event. Otherwise the browser will attempt to go to that URL (which it obviously isn't).
I seen many post regarding same problem but i am not getting exact solution. i want to delete cookie on browser or tab close event using javascript. I have made delete cookie function and called on onbeforeunload event. But i seen that event also called when page refresh i dont want to delete cookie on page refresh. And i seen in many post that they are detecting link click, keypress event of F5 and form submit and in that they preventing onbeforeunload event. But then what about refresh button click and press enter at url bar. So i think this is not a exact solution. so help me out from this problem.
Further information is i am creating cookie using PHP and want to delete this cookie on browser close.
Cookies are automatically deleted when the browser is closed, unless you specify a lifetime for the cookie.
If you want to delete a cookie on browser close, better would be to check if cookie exists on page load and delete that.
To delete all the cookies when browser close uses the following code
$(window).bind('beforeunload', function(event) {
var cookies = $.cookie();
for(var cookie in cookies) {
$.removeCookie(cookie);
}
return true;
});
Hope this will solve your problem.
Suppose I have a page open in a browser and I go to my address bar and enter another page. Then I hit the back button to go to my original page. I'd like to write some Javascript code that can detect this scenario and respond to it.
As best I can tell neither the ready event, the onload, nor any inline Javascript on the page itself is re-executed in this scenario. Is there anything else I can do?
Cross-browser support is important here. jQuery based solutions preferred but not required.
Edit for clarity: the navigation I'm assuming is Page A -> Page B -> back to page A where I'm assuming that Page B may or may not be under my control.
You should try to give the user a cookie on both pages, the navigated to page and the page itself, with dates and times and compare see if they're close, or if they show that he's been on one page, been on another, and then redirected.
Another option is to give the user a cookie when he is redirected
In Firefox, you can check for the DomContentLoaded event. For a cross-browser solution, a little more work is required:

Hi I have the following code:
function redirect(){
window.location.href='logged_out_chat.php';
}
...in my header and the following body tag:
<body onunload="javascript:redirect();">
...when i try this on one laptop, it redirects as it is supposed to (when you click on any link), but on my other laptop, desktop and notebook it ignores the redirect and goes to any link you click on.
I have spent hours on this...all have the same browser. I was wondering if there is an alternative way i could redirect the user when they click on a link etc.
What do you expect would happen?
When I close your page in my browser you get to redirect me to a page of your liking?
This goes againts security and user control. You shouldn't be able to interfere with the page when I close it.
The morale is don't rely on onunload to do anything non-trivial.
When a window unloads it stops processing everything, that means ajax requests, pending downloads etc, most even freeze animated gifs. Some browsers support onbeforeunload, but I completely agree with #Raynos you can't count on the event, so using it is not a good design decision.
You can't hijack onunload and redirect the user. That would prevent the user from closing their browser, refreshing the page, or manually navigating to another site. If that's what you are trying to do, you are out of luck. All onunload is good for is asking the user if they are sure they want to leave the page.
If, however, you are trying to cause a clicked link to go to a different location, that's easy. To change the link permanently:
myLink.href = 'logged_out_chat.php';
If you want to change the links temporarily, add a click handler that you can later remove:
function goToLoggedOutChat(e)
{
e.preventDefault && e.preventDefault();
e.returnValue = false;
location.href = 'logged_out_chat.php';
}
mylink.onclick = goToLoggedOutChat;
To re-enable the link:
mylink.onclick = null;
To do it for every link on the page:
for (var i=0; i<document.links.length; i++)
{
document.links[i].onclick = goToLoggedOutChat;
}
I have written code like this to throw a pop up when my website is closed. But this throws the pop up even if i refresh my page. Please help me to throw popup only when i close the browser of that website. (disable popup on refreshing page)
<body onunload="javascript: exitpop()">
<script type="text/javascript">
function exitpop()
{
my_window= window.open ("","mywindow1","status=1,width=600,height=400");
my_window.document.write('<h1>My Team</h1><p>Thank you</p><p>If you accidentally closed website click here to go back to our website</p>');
}.
onUnLoad is called on a refresh because the browser is requesting a new page (well, the same page in the case of a refresh, but it is still a new call).
I am not sure if there is a way to check where the user is going next, but if there is you could compare it to their current url, if they are the same then the user is just refreshing and the script doesn't need to be run.
Good luck
Sadly, this is not possible. To the browser, it is essentially the same action.
However, if you just use a confirm() box, you can catch a user that is trying to leave without linking them back. If they are refreshing or if they really want to leave, hitting "OK" will allow that action to occur.
Let me know if you need this explained further.
