回答1:

In bbb.jsp:

window.onbeforeunload = function() { 
    window.setTimeout(function () { 
        window.location = 'AAA.jsp';
    }, 0); 
    window.onbeforeunload = null; // necessary to prevent infinite loop, that kills your browser 
}

回答2:

Windows onload loads after all the content is loaded, little bit slow other workaround is to use document.onload(Browser compatibility issue)

window.onload = function () {
  window.location = "/allotment";
}

below code will work for you

function confirmExit()
{
 alert("exiting");
 window.location.href='index.html';
 return true;
}
window.onbeforeunload = confirmExit;

This has worked for me. Not the second attempt part, but changing URL after showing the popup. If you hit cancel, the function is not ran. If you click "Reload", the function is called and you will be redirected.

$(window).on('beforeunload', function() {
  $(window).on('unload', function() {
    window.location.href = 'index.html';
  });

  return 'Not an empty string';
});
