移动重定向，但不是来自移动网站

Question

i have this script and it works fine. I have it on the Desktop page and when a user enters it they get a question to be redirected to mobile page, this works fine. But i then have on the mobile page a link back to Desktop page, but when this link is clicked and the user gets to the Desktop page they will get the quetsion again. So my question is. Is there a way to let the Desktop page know that the user have clicked the link in Mobile page and if so do not show the Question again? Thank you.

The code i have now:

<script type="text/javascript">
var isMobile = (/iphone|ipod|android|blackberry|mini|windows\sce|palm/i.test(navigator.userAgent) && confirm('Realy?'));
if (isMobile)
{
   location.replace("mobile_site.html");
}  
</script>

So i also have this code. Any one know how to combind my first script with this one? Thank you.

<script>
if( /Android|webOS|iPhone|iPod|BlackBerry|IEMobile/i.test(navigator.userAgent) &&
    !window.location.href.contains("#redirected") ) {
window.location = "my_mobile_page.html";
}
</script>

Answer 1

This should do it - only re-direct to your mobile site if the user device isMobile and if the user has not just linked from that mobile site:

<script type="text/javascript">
  var referrer = document.referrer;
  var isMobile = (/iphone|ipod|android|blackberry|mini|windows\sce|palm/i.test(navigator.userAgent) && confirm('Realy?'));
  if (isMobile && referrer != 'mobile_site.html')
    {
     location.replace("mobile_site.html");
    }  
</script>

EDIT: Revised code to remove confirmation. If the user's device is mobile, and the referrer is not the mobile site, the confirmation prompt will display. If the user accepts it, the re-direction will be triggered. If the user is returning from the mobile site, the confirmation will not be shown.

<script type="text/javascript">
      var referrer = document.referrer;
      if (/iphone|ipod|android|blackberry|mini|windows\sce|palm/i.test(navigator.userAgent) && referrer != 'mobile_site.html')
        {
        var r = confirm("Really");
            if (r == true) {
                location.replace("mobile_site.html");
            }  else {
                stop;
            }
        }
    </script>
