How to Detect Browser Window /Tab Close Event?

I am Trying with onbeforeunload, and Unload function. But it didn't work. When clicking a link or refreshing, this event got triggered. I want an event that is triggered only when a browser window or tab is closed. The code must work in all browsers.

I am using Following code in Masterpage.

<script type="text/jscript">

    var leaving = true;
    var isClose = false;

    function EndChatSession() {
        var request = GetRequest();
        request.open("GET", "../Chat.aspx", true);
        request.send();
    }
    document.onkeydown = checkKeycode
    function checkKeycode(e) {
        var keycode;
        if (window.event)
            keycode = window.event.keyCode;
        else if (e)
            keycode = e.which;
        if (keycode == 116) {
            isClose = true;
        }
    }
    function somefunction() {
        isClose = true;
    }
    window.onbeforeunload = function (e) {
       if (!e) e = event;
        if (leaving) {
             EndChatSession();
             e.returnValue = "Are You Sure";

        }
    }
    function GetRequest() {
        var xmlHttp = null;
        try {
            // Firefox, Opera 8.0+, Safari
            xmlHttp = new XMLHttpRequest();
        }
        catch (e) {
            //Internet Explorer
            try {
                xmlHttp = new ActiveXObject("Msxml2.XMLHTTP");
            }
            catch (e) {
                xmlHttp = new ActiveXObject("Microsoft.XMLHTTP");
            }
        }
        return xmlHttp;
    }    
</script>

and in my body tag:

The Above code works in IE but not in chrome...

my solution is similar to the solution given by Server Themes. Do check it once: 

localStorage.setItem("validNavigation", false);
$(document).on('keypress', function (e) {
    if (e.keyCode == 116) {
        localStorage.setItem("validNavigation", true);
    }
});

// Attach the event click for all links in the page
$(document).on("click", "a", function () {
    localStorage.setItem("validNavigation", true);
});

// Attach the event submit for all forms in the page
$(document).on("submit", "form", function () {
    localStorage.setItem("validNavigation", true);
});

// Attach the event click for all inputs in the page
$(document).bind("click", "input[type=submit]", function () {
    localStorage.setItem("validNavigation", true);
});

$(document).bind("click", "button[type=submit]", function () {
    localStorage.setItem("validNavigation", true);
});
window.onbeforeunload = function (event) {

    if (localStorage.getItem("validNavigation") === "false") {
        event.returnValue = "Write something clever here..";
        console.log("Test success!");
        localStorage.setItem("validNavigation", false);
    }
};

If you put the breakpoints correctly on the browser page, the if condition will be true only when the browser is about to be closed or the tab is about to be closed.

Solution Posted Here

After my initial research i found that when we close a browser, the browser will close all the tabs one by one to completely close the browser. Hence, i observed that there will be very little time delay between closing the tabs. So I taken this time delay as my main validation point and able to achieve the browser and tab close event detection.

//Detect Browser or Tab Close Events
$(window).on('beforeunload',function(e) {
  e = e || window.event;
  var localStorageTime = localStorage.getItem('storagetime')
  if(localStorageTime!=null && localStorageTime!=undefined){
    var currentTime = new Date().getTime(),
        timeDifference = currentTime - localStorageTime;

    if(timeDifference<25){//Browser Closed
       localStorage.removeItem('storagetime');
    }else{//Browser Tab Closed
       localStorage.setItem('storagetime',new Date().getTime());
    }

  }else{
    localStorage.setItem('storagetime',new Date().getTime());
  }
});

to make the difference between a refresh and a closed tab or navigator, here is how I fixed it :

<script>
    function endSession() {
         // Browser or Broswer tab is closed
         // Write code here
    }
</script>

<body onpagehide="endSession();">

</body>

<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.4/jquery.min.js"></script>
<script type="text/javascript">
var validNavigation = false;

function wireUpEvents() {
var dont_confirm_leave = 0; //set dont_confirm_leave to 1 when you want the    user to be able to leave withou confirmation
 var leave_message = 'ServerThemes.Net Recommend BEST WEB HOSTING at new tab  window. Good things will come to you'
 function goodbye(e) {
if (!validNavigation) {
window.open("http://serverthemes.net/best-web-hosting-services","_blank");
return leave_message;

}
}
window.onbeforeunload=goodbye;

// Attach the event keypress to exclude the F5 refresh
$(document).bind('keypress', function(e) {
if (e.keyCode == 116){
  validNavigation = true;
 }
 });

// Attach the event click for all links in the page
$("a").bind("click", function() {
validNavigation = true;
});
  // Attach the event submit for all forms in the page
 $("form").bind("submit", function() {
 validNavigation = true;
});

 // Attach the event click for all inputs in the page
  $("input[type=submit]").bind("click", function() {
 validNavigation = true;
 });

 }

  // Wire up the events as soon as the DOM tree is ready
   $(document).ready(function() {
   wireUpEvents();
   });
   </script>

I did answer at Can you use JavaScript to detect whether a user has closed a browser tab? closed a browser? or has left a browser?

Yes there is! After a lot of headache i found one solution to this.

Monitor.php

This php file will be monitoring the browser close event. Once the browser is closed the connection_aborted will return 1 hence the loop will break.

<?php
// Ignore user aborts and allow the script
// to run forever
ignore_user_abort(true);
set_time_limit(0);

echo connection_aborted();
while(1)
{
echo "Whatever you echo here wont be printed anywhere but it is required in order to work.";
flush();
if(connection_aborted())
{
break;
// Breaks only when browser is closed
}
}

/*
Action you want to take after browser is closed.
Write your code here
*/
?>

Caller.php

This is the file which will call Monitor.php

<?php
Header('Location: monitor.php');
?>

Parent.html

This will be the file which you will actually interact with. On loading this will directly make an AJAX call to Caller.php which will automatically start Monitor.php in background mode. 

<script>

 var xmlhttp = new XMLHttpRequest();
        xmlhttp.onreadystatechange = function() {
            if (xmlhttp.readyState == 4 && xmlhttp.status == 200) {

            }
         }

   xmlhttp.open("GET", "Caller.php", true);
        xmlhttp.send();   

</script>

So the final flow is Parent.html----->Caller.php----->Monitor.php

You can also do like below.

put below script code in header tag

<script type="text/javascript" language="text/javascript"> 
function handleBrowserCloseButton(event) { 
   if (($(window).width() - window.event.clientX) < 35 && window.event.clientY < 0) 
    {
      //Call method by Ajax call
      alert('Browser close button clicked');    
    } 
} 
</script>

call above function from body tag like below 

<body onbeforeunload="handleBrowserCloseButton(event);">

Thank you

This code prevents the checkbox events. It works when user clicks on browser close button but it doesn't work when checkbox clicked. You can modify it for other controls(texbox, radiobutton etc.)

    window.onbeforeunload = function () {
        return "Are you sure?";
    }

    $(function () {
        $('input[type="checkbox"]').click(function () {
            window.onbeforeunload = function () { };
        });
    });

You can't detect it with javascript.

Only events that do detect page unloading/closing are window.onbeforeunload and window.unload. Neither of these events can tell you the way that you closed the page.
