Javascript Detect browser close event alert message

it is not working for google chrome!!

I dont want the message to be given to user if the browser gets refreshed..i need a notification only when the user clicks on (X) to close the browser..please help

HI Thanks,

The script you all mentioned above is working but onbeforeunload event is being fired on browser close as well as on page refresh. Is there any way to fire this event only on browser close not on page refresh. For F4 and CTRL+F4 we can trace key code and prevent them but what to do in case of browser refresh button click or if someonel click in address bar and press enter. In these cases your script is not working. I would appreciate any help in it. Looking forward to hear you you.

var validNavigation = false;
var test=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 = ‘You sure you want to leave?’
function goodbye(e) {
if (!validNavigation) {
if (dont_confirm_leave!==1) {
if(!e) e = window.event;
//e.cancelBubble is supported by IE – this will kill the bubbling process.
e.cancelBubble = true;
e.returnValue = leave_message;
//e.stopPropagation works in Firefox.
if (e.stopPropagation) {
e.stopPropagation();
e.preventDefault();
}
//return works for Chrome and Safari
return leave_message;
}
}
}

window.onbeforeunload= (function(event){

if(!validNavigation){
return goodbye(event);
}
})
// Attach the event keypress to exclude the F5 refresh
$(document).bind(‘keydown’, function(e) {
getKeyCode(e);

if (keyCd == 116){
validNavigation = true;
}

if (altKy && (keyCd == 18 || keyCd == 115)) {
validNavigation = true;
}
if (keyCd == 13) {
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;
});

}

function getMouseButton(event) {
if (IE == true) {
mouseBtn = event.button;
}
if (Netscape == true) {
if (event.which == null)
mouseBtn = event.button;
else
mouseBtn = event.which;

}
}
function getKeyCode(event) {
if (IE == true) {
keyCd = event.keyCode;
altKy = event.altKey;
ctlKy = event.ctlKey;
shiftKy = event.shiftKey;
}
if (Netscape == true) {
if (event.which == null)
keyCd = event.keyCode;
else
keyCd = event.which;

altKy = event.altKey;
ctlKy = event.ctrlKey;
shiftKy = event.shiftKey;
}

}
// Wire up the events as soon as the DOM tree is ready
$(document).ready(function() {
var keyCd, altKy, mouseBtn, ctlKy, shiftKy;
Browser = navigator.appName
Net = Browser.indexOf(“Netscape”)
Micro = Browser.indexOf(“Microsoft”)
Netscape = false
IE = false
if (Net >= 0) {
window.captureEvents(Event.MOUSEDOWN)

Netscape = true
}
if (Micro >= 0) {
IE = true
}
wireUpEvents();

});
