Can we stop browser close using
Javascript?
Some time it’s better to give a warning to user when he trying to close
the browser. Some browsers has the facility by default but they can be
disabling from the browser itself. So it’s better to give a warning message to
user from the application itself. In this case we can use JavaScript for given
the confirm message to user before close the browser window.

user on browser closing event. We can achieve it by call a event
‘onbeforeunload’ from the body tag. This event will fired when a user close the
browser. On this event we are calling a function quit(), On this function we
are given a confirm message to user and return the result. If user clicks OK
browser will close, if user press cancel it will return to the browser
