Fire onbeforeunload confirm alert for external sites only

Question

I am using window.onbeforeunload method to show confirm message if user leaves website.

window.onbeforeunload = function(e) {
    return textMsg;
};


        

Answer 1

Try (untested code):

window.onbeforeunload = function(e) {
    return textMsg;
};

$('a:not([href^="http"])').on('click', function() {
    window.onbeforeunload = null; // prevent message
});

$('form').on('submit', function() {
    window.onbeforeunload = null; // prevent message
});

This will prevent the event from triggering if links do not start with http (external links) and for <form> submits. Looking for a solution for window closing at the moment.
