How to auto re-direct from other url?

Question

I'm writing for a condizionale auto re-direct url, but it doesn't works. I tried with two methods:

<script>

      function mobileDevice()

        {

        $type = $_SERVER[‘HTTP_USER_AGENT’];

        if(strpos((string)$type, “Windows Phone”) != false || strpos((string)$type, “iPhone”) != false || strpos((string)$type, “Android”) != false)

        return true;

        else

        return false;

        }

        if(mobileDevice() == true)

        header(‘Location: https://www.organization.org/mobile/index_mobile.htm‘);

</script>

and

<script type="text/javascript">

      if (screen.width <= 414) {

        document.location = "index.htm";

        <script language=javascript>

    if ((navigator.userAgent.match(/iPhone/i)) || (navigator.userAgent.match(/iPod/i))) {

       location.replace("https://www.organization.org/mobile/index_mobile.htm");

    }

          </script>

      }

    </script>

As I yet announced, no one of this works, why?

Answer 1

In plain Javascript you should assign the value location instead of using method to redirect. replace method won't save in history the change of url.

window.location = "https://www.organization.org/mobile/index_mobile.htm";

Also you are nesting two tags in your second approach. The correct code would be:

<script type="text/javascript">
      if (screen.width <= 414) {
        document.location = "index.htm";
        if ((navigator.userAgent.match(/iPhone/i)) || (navigator.userAgent.match(/iPod/i))) {
          location.replace("https://www.organization.org/mobile/index_mobile.htm");
        }
      }
</script>
