Try using nametop.location.host, something like this:

HTML Code:

<script language = "JavaScript">
function name ()
{
alert (nametop.location.host);
}
</script>

To get host name in JavaScript add

Code:

var hostname = window.location.hostname

this statement in your code.

However if you want you can use "VIH_HostName" variable. The client host name is stored in this variable.

Here is a simple example how to get the hostname of your web site. Basically the hostname property of Location class represents the hostname portion of the URL.

HTML Code:

<html>
    <head>
    <title> Using the hostname property of the Location object</title>
    </head>
    <body>
    <script language="JavaScript">
    <!--
    function show(){
         alert(document.location.hostname);
    }
    -->
    </script>
    <form name="form1">
    Click the button to get the current location.hostname
    <br>

    <br>
    <input type="button" name="gethost" value="Get hostname" onClick='show()'>
    <br>
    </form>
    </body>
    </html>
