将 IE9 和 IE8 访问者重定向到同一网站的不同主页

Question

On my Wordpress site, Homepage has some JavaScripts and links that are not working on IE9. The theme developer saying that IE9 is not compatible and not taking the responsibility.

Now, I have created another page with the same exact look but no Javascript on that. I want to redirect IE9 user to that page when they open the site.

I tried different codes in header.php one of the code is

<script type="text/javascript">
  if (navigator.userAgent.indexOf('MSIE') !=-1){
    window.location = "http://newpage.com"
  }
</script>

Problem is, this code redirect all website links to the redirected link but I only want to redirect the home page.

I will really appreciate if someone can help.

Thank you.

Answer 1

As per Phiter's comment, this is something that can and probably should be done on the server side with a redirect, but if you really want to do it on the client side, simply expand your test case to compare the current window location:

if (navigator.userAgent.indexOf('MSIE') !=-1 
    && window.location === "http://homepage.com"){
  window.location = "http://newpage.com"
}

This could be done with an exact match like above, or a regular expression.

Answer 2

Redirection working after putting that code directly on my homepage. If I put this code in Header of theme then it will redirect all web pages.

if (navigator.userAgent.indexOf('MSIE') !=-1){
window.location = "http://newpage.com"

}

But this is only working on IE9 and not on IE8.Any clue.
