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

<head>
<script>

    window.onbeforeunload = func;

    function func() 
    {
        var request = new XMLHttpRequest();
        request.open("POST", "exit.php", true); 
        request.onreadystatechange = stateChanged;
        request.send(null);
    }
    function stateChanged()
    {
        if (request.readyState == 4 || request.readyState == "complete")
            alert("Succes!");
    }
    </script>
    </head>

this works with IE and mozila but does not work with chrome..... please help...... thanks in advance.....

Answer

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.
