jQuery is not necessary, and
window.location.replace(...)will best simulate an HTTP redirect.It is better than using
window.location.href =, becausereplace()does not put the originating page in the session history, meaning the user won't get stuck in a never-ending back-button fiasco. If you want to simulate someone clicking on a link, uselocation.href. If you want to simulate an HTTP redirect, uselocation.replace. -
// similar behavior as an HTTP redirect
window.location.replace("http://stackoverflow.com");
// similar behavior as clicking on a link
window.location.href = "http://stackoverflow.com";
