I need to stop all the page redirection through javascript.

I have some script which will redirect the page to some other location. How can I stop all the page redirection on my page through jquery or javascript.

You can stop the redirect by doing the following.

<script language="JavaScript" type="text/javascript">
    //<![CDATA[
        window.onbeforeunload = function(){
            return 'Are you sure you want to leave?';
        };
    //]]>
</script>

Not sure if all browsers support this but that should do the trick.

    It's ingenious in it's simplicity. On a sidenote - it's the only method that appears to stop malicious scripts from redirecting using `window.location.replace()` or `window.location.href="virus"` type of things. Helped me with debugging, so thanks a lot. – Krzysztof Jabłoński Nov 10 '18 at 01:23
  • Is it possible to get the URL that it is redirecting to using this method? – NPC Jun 18 '21 at 16:15

If I'm understanding you correctly, you need to stop users navigating away from the page?

If so, Marcos Placona's answer is one part of it - although all what you actually need is:

$("a").click(function(e) { e.preventDefault(); });

You also don't want people to hit F5 I'm guessing? Well that's harder. Preventing defaults on key press, cross-browser is horrible. But a couple of codes that work in some browser are below here:

function disableF5() {  // IE
    document.onkeydown = function() {
        if (window.event && window.event.keyCode == 116) { // Capture and remap F5
            window.event.keyCode = 505;
        }
        if (window.event && window.event.keyCode == 505) { // New action for F5
        return false; // Must return false or the browser will refresh anyway
        }
    }
}
function disableF5v2() { // FIREFOX
    $(this).keypress(function(e) {
        if (e.keyCode == 116) {
            e.preventDefault();
    return false;
        }
    });
}

However, the cross-browser issue can partly be solved with - 

window.onbeforeunload = function(e) {
    var message = "Your confirmation message goes here.", e = e || window.event;
    // For IE and Firefox 
if (e) {
    e.returnValue = message;
}
// For Safari
    return message;
};

Hope that all helps anyway. The last bit of code is from another question on this site here. Rob

Are you trying to stop an iframe breaker? Something like: 

<script language="JavaScript" type="text/javascript">
<!--
function breakout_of_frame()
{
  if (top.location != location) {
    top.location.href = document.location.href ;
  }
}
-->
</script>

If so, you can not.

    HTML5 supports `sandboxed` iframes. "prevent the content to navigate its top-level browsing context". http://www.w3schools.com/tags/att_iframe_sandbox.asp – kev Oct 20 '16 at 01:03

If it's only redirects through link clicks, in jQuery you can do this:

$(".someClass a").unbind('click');

if it's an existing page redirect, you'll need to give us some more information about what kind of redirect this is, so we can help further.

Hope this helps you

    that would assume all anchors are bound by jQuery. To be sure one should use $(a).unbind('click'), $(a).die(), $(a).removeAttr('onClick') – jAndy Apr 14 '10 at 07:02
  • In jQuery >= 1.7, you should use `.off()` instead of `.unbind()` – developius Jan 27 '16 at 19:27

AFAIK this won't be possible, since page redirection can occur in many ways. He can click on an anchor tag, can submit a form with different action, set window.location to another page on button click and invoke server code to redirection.

And you won't be able to detect many of these.
