        req.onreadystatechange = function()
        {
            //when state is completed i.e 4
            if (req.readyState == 4) 
            {           
                // only if http status is "OK"
                if (req.status == 200)
                {   

                        document.getElementById('location').value=req.responseText;
                        document.getElementById('msrno').value=req.responseText;
