How do I redirect to another webpage?
One does not simply redirect using jQuery
jQuery is not necessary, and window.location.replace(...)
will best simulate an HTTP redirect.
window.location.replace(...)
is better than using window.location.href
, because replace()
does not keep 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
For example:
// similar behavior as an HTTP redirectwindow.location.replace("http://stackoverflow.com");// similar behavior as clicking on a linkwindow.location.href = "http://stackoverflow.com";
WARNING: This answer has merely been provided as a possible solution; it is obviously not the best solution, as it requires jQuery. Instead, prefer the pure JavaScript solution.
$(location).attr('href', 'http://stackoverflow.com')
Standard "vanilla" JavaScript way to redirect a page
window.location.href = 'newPage.html';
Or more simply: (since window
is Global)
location.href = 'newPage.html';
If you are here because you are losing HTTP_REFERER when redirecting, keep reading:
(Otherwise ignore this last part)
The following section is for those using HTTP_REFERER
as one of many security measures (although it isn't a great protective measure). If you're using Internet Explorer 8 or lower, these variables get lost when using any form of JavaScript page redirection (location.href, etc.).
Below we are going to implement an alternative for IE8 & lower so that we don't lose HTTP_REFERER. Otherwise, you can almost always simply use window.location.href
.
Testing against HTTP_REFERER
(URL pasting, session, etc.) can help tell whether a request is legitimate.(Note: there are also ways to work-around / spoof these referrers, as noted by droop's link in the comments)
Simple cross-browser testing solution (fallback to window.location.href for Internet Explorer 9+ and all other browsers)
Usage: redirect('anotherpage.aspx');
function redirect (url) { var ua = navigator.userAgent.toLowerCase(), isIE = ua.indexOf('msie') !== -1, version = parseInt(ua.substr(4, 2), 10); // Internet Explorer 8 and lower if (isIE && version < 9) { var link = document.createElement('a'); link.href = url; document.body.appendChild(link); link.click(); } // All other browsers can use the standard window.location.href (they don't lose HTTP_REFERER like Internet Explorer 8 & lower does) else { window.location.href = url; }}
