It is better than using window.location.href =, because replace() 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, use location.href. If you want to simulate an HTTP redirect, use location.replace.
// simulates similar behavior as an HTTP redirect window.location.replace("http://stackoverflow.com"); // simulates similar behavior as clicking on a link window.location.href = "http://stackoverflow.com";
var url = "http://stackoverflow.com"; $(location).attr('href',url);
