How to redirect Internet Explorer users to a new page?

Question

I have tried using the following script

[if IE]
<script type="text/javascript">
window.location = "error.html";
</script>
[endif]

It works like a treat apart from the fact that other browsers such as Chrome are also redirecting to the error.html page. What is wrong with it? Thanks

Don't. Seriously. If people want to use IE, especially modern IE. Let them. Use feature detection and progressive enhancement instead. — Quentin, Oct 07 '14 at 14:19

Try this:

<script type="text/javascript">
if(navigator.appName.indexOf("Internet Explorer")!=-1 || navigator.userAgent.match(/Trident.*rv[ :]*11\./))
{
   //This user uses Internet Explorer
   window.location = "error.html";
}
</script>

That won't match IE 11. http://blogs.msdn.com/b/ieinternals/archive/2013/09/21/internet-explorer-11-user-agent-string-ua-string-sniffing-compatibility-with-gecko-webkit.aspx – Quentin Oct 07 '14 at 14:18
Now it thinks Chrome is IE11 – Quentin Oct 07 '14 at 14:26
It would appear not to be working. Just to clarify, where is the error.html supposed to be put? – Tom Oct 07 '14 at 14:52

I know there have been answers all around, but here is in my opinion the most complete answer..

HTML

<p>Is this internet explorer?<p>
<p id="ie"></p>

And now the JavaScript

if(detectIE()){
  document.getElementById("ie").innerHTML = "Yes it is!";
} else {
  document.getElementById("ie").innerHTML = "No it's not!";
}

function detectIE() {
  var ua = window.navigator.userAgent;

  var msie = ua.indexOf('MSIE ');
   if (msie > 0) {
     return true;
   }

  var trident = ua.indexOf('Trident/');
   if (trident > 0) {
    return true;
   }

  var edge = ua.indexOf('Edge/');
  if (edge > 0) {
    return true;
  }

  // other browser
  return false;
}

You need to use conditional comments.

Keep in mind though, IE10+ does not respect these conditional comments and will treat them the same way Firefox and Chrome does.

<!--[if IE]>
<script type="text/javascript">
window.location = "error.html";
</script>
<![endif]-->

Try this:

if (window.navigator.userAgent.indexOf("MSIE ") > 0)
    window.location="error.html";
