logout auto when client close the browser

Mohmed, Try this solution:

window.addEventListener('beforeunload', function (e) {
    // Cancel the event
    e.preventDefault(); // If you prevent default behavior in Mozilla Firefox prompt will always be shown
    // Chrome requires returnValue to be set
    e.returnValue = '';
});

window.onunload = function () {
    logoff();
};

function logoff() {
    // Async AJAX call to log off the user from the server
    var xhr = new XMLHttpRequest();
    xhr.open("POST", "/PathToYourLogoutMethod", true); // Adjust the path to your logout method
    xhr.send();
}
