Try this:

<html>
<head>
<script>
var xPar="";
if(window.location.href.match(/x=(\d+)/i))
  xPar=RegExp.$1
alert(xPar)
</script>
</head>
</html>

var urlString = "http://www.asfdjklasfd.com/card.html?x=123456";
var urlLength = url.length;

var lastSixDigits = urlString.substring( urlLength - 6, 6 );

<script language="javascript">
var address = window.top.location.href
address = address.substring(address.length-6,address.length)
</script>

type wrongly use 6 instead of address.length

<script language="javascript">
var address = window.top.location.href
address = address.substring(address.length-6,6)
</script>
