Session is server side, you cannot check by JavaScript. That’s why PHPMaker uses a timer based on your advanced settings, see Session timeout period (minutes).

if we use ew.fetchJson()
how this handled when session is logout

There is no ew.fetchJson(). Did you mean ew.fetch()? Anyway, there is no direct way to check “session is logout” by JavaScript. However, if the user is not logged in, there is no current user info passed to the client side, e.g. ew.CURRENT_USER_NAME == ''.

document.addEventListener('click', function() {
  if (typeof ew !== 'undefined' && typeof ew.CURRENT_USER_NAME !== 'undefined') {
    console.log(ew.CURRENT_USER_NAME);
  } else {
    console.log("ew or ew.CURRENT_USER_NAME is not defined.");
  }
});

the ew.CURRENT_USER_NAME always show the username on the custom page when the session logout also.

As explained your other topic, if you logs out in other browser, it will not affect your current status in another browser on the client side, until you refresh the page or go to another page.
