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

• 2 Don't. Seriously. If people want to use IE, especially modern IE. Let them. Use feature detection and progressive enhancement instead. – Quentin Commented Oct 7, 2014 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>

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

Keep in mind though, IE10+ does not respect these conditional ments 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";
