what need @ loading partial view via ajax request after selections have been made.

    var selection1 = $(".selection1radiobutton").val();     $.ajax({     type: "get",     url: "/home/getsomepartialview?selection1=" + selection1,     data: somearguments,     success: function (viewhtml) {          $("#somediv").html(viewhtml);      },     error: function (errordata) { onerror(errordata); }     }); 

and repeat selection 2.
