I need to pop up an alert while closing my application in firefox and I am using the latest version of fire fox. I used unload,onbeforeunload But nothing works
I have used the following code:
var myEvent = window.attachEvent || window.addEventListener;
var chkevent = window.attachEvent ? 'onbeforeunload' : 'beforeunload'; /// make IE7, IE8 compitable
myEvent(chkevent, function(e) { // For >=IE7, Chrome, Firefox
var confirmationMessage = 'Are you sure to leave the page?'; // a space
(e || window.event).returnValue = confirmationMessage;
return confirmationMessage;
});
I have used the following code:
var myEvent = window.attachEvent || window.addEventListener;
var chkevent = window.attachEvent ? 'onbeforeunload' : 'beforeunload'; /// make IE7, IE8 compitable
myEvent(chkevent, function(e) { // For >=IE7, Chrome, Firefox
var confirmationMessage = 'Are you sure to leave the page?'; // a space
(e || window.event).returnValue = confirmationMessage;
return confirmationMessage;
});
