How can I stop this event from occurring on browser refresh? Here is the code:
if ($("body").attr('onbeforeunload') == null) {
if (window.event) {
    // IE and Chrome use this
    $("body").attr('onbeforeunload', 'CatchLeavePage(event)');
    <?php
    // Log out when browser is closed
    echo "  location.href=\"/logout.php\"";
    ?>      
}
