答

最好设置会话时间清除，即使你想在关闭时设置它你可以参考下面的代码

Hi,

Its better to set time for session clear, even though you want to set it while closing you could refer the below code

function CloseSession( )
{
    //Trigger logout button click event to force to logout the application
    document.getElementById('btnLogout').click();
}
window.onbeforeunload = CloseSession;

希望这对你有所帮助。

问候，

Hope this helps you a bit.
