javascript - Clear session on window close -

Open () If the user closes a test before the end of the session then the session creates a problem, so I want to end the session when the user closes the browser window or close / disable button before the trial is complete Closes.

to pop up the dialog) But even so It is very easy to bypass any person how to open a browser console (for example, F12 on each browser), because they can only redefine the window.confirm = ((=) => true) Are;
and are not bothered by the confirmation dialog.
