Answer 1

You could pass this variable as query string parameter to some controller action:
<script type="text/javascript">
var mySerial = '12345';
$.ajax({
url: '#Url.Action("Foo", "Home")',
type: 'POST',
data: { mySerial: mySerial },
success: function(result) {
alert('success');
}
});
</script>
and the Foo action:
[HttpPost]
public ActionResult Foo(string mySerial)
{
... do something with the serial here
}
Another possibility is to perform a redirect if you don't want to use AJAX:
<script type="text/javascript">
var mySerial = '12345';
var fooUrl = '#Url.Action("Foo", "Home")';
window.location.href = fooUrl + '?mySerial' + encodeURIComponent(mySerial);
</script>
Or maybe I misunderstood your question and you want to assign your javascript variable to some value coming from the view model? In this case:
<script type="text/javascript">
var mySerial = #Html.Raw(Json.Encode(Model.MySerial));
</script>

you could pass value from your jquery to controller action like this ...
$(document).ready(function()
{
var postdata = { name: "your name", Age: "your age" };// you can pass control values
$.ajax({
ur: /home/index,
data: postdata,
success: function(returndata)
{
// do something here for the return data...
}
});
});
in your controller
public ActionResult PostedDAta(string myname, string myage)
{
// do somethign here and return Json back to Jquery code
return Json(data,JsonRequestBehaviour.AllowGet);
}
