[removed] not working in chrome

Question

This is the code which i used for window.onbeforeunload......

Answer 1

Try this, it worked for me:

window.onbeforeunload = function(event) {
    event.returnValue = "Write something clever here..";
};

Answer 2

It seems that the only thing you can do with onbeforeunload in recent version of Chrome is to set the warning message.

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

Will work. Other code in the function seems to be ignored by Chrome

UPDATE: As of Chrome V51, the returned string will be ignored and a default message shown instead.

Answer 3

Try this. I've tried it and it works. Interesting but the Succes message doesn`t need confirmation like the other message.

window.onbeforeunload = function() 
{
    if ( window.XMLHttpRequest )
    {
        console.log("before"); //alert("before");
        var request = new XMLHttpRequest();
        request.open("POST", "exit.php", true); 
        request.onreadystatechange = function () {
            if ( request.readyState == 4 && request.status == 200 )
            {
                console.log("Succes!"); //alert("Succes!");
            }
        };
        request.send();
    }
}
