Returning a set of values from JS to C#

Question

I have a function that returns an element's top and left position, like so

    $(function GetPos(El) {
      var Offset = $(El).Offset();
      var Top = Offset.Top;
      var Left = Offset.Left;
      return { x: Top, y: Left };
  });

I need to be able to assign and store those values using C# . I think Ajax could be the answer, but I don't know how I would set it up.

I'd like to do something like:

    Int Top = someAjax[1];

Here is a better example using jQuery - this is probably the easiest way to do it.

$.ajax({
      type: "POST",
      url: "Default.aspx/DoSomething",
      data: {someParam: "some val"},
      contentType: "application/json; charset=utf-8",
      dataType: "json",
      success: function(msg) {
          //If anything needs to done after ajax call happens
      }
    });

On the server:

public void DoSomething(string someParam)
{
    //Do whatever you need to
}
