[b u d d h a]

hi,

am trying to call a server function like this

$(document).ready(function (){
    $('#Button1').click(function()
    {
        $.ajax({
                    type: "POST",
                    url: "remotefunctions.aspx/Test",
                    data: "{'str':'1'}",
                    contentType: "application/json; charset=utf-8",
                    dataType: "json",

                    error: function (xhr) {alert(xhr.statusText);},
                    success: function(msg)
                        {

                            //alert(msg);
                            var result = msg;
                            alert(msg)
                            alert("hI");

                        }


                    });
    });
});
