步骤：
0.html：

<input id="btn" type="button" value="ajax json" />     <input id="btn2" type="button" value="ajax content" />     <input id="txt4" type="text" value="456" />    <input id="txt1" type="text" value="123" />     <input id="txt2" type="text" value="234" />     <input id="txt3" type="text" value="345" />

1.使用json数据形式

$(document).ready(function () {        $("#btn").click(function () {                        $.ajax({                type: 'POST',                url: "/Student/MyAjax",                data: {                    val1: $("#txt1").val(),                    val2: $("#txt2").val(),                    val3: $("#txt3").val(),                    val4: $("#txt4").val()                },                 success: function (obj) { alert(obj["stuNo"] + "," + obj["classId"] + "," + obj["name"]);},                dataType: "json"                           });                    });    });

[HttpPost]//记得要加HTTPPOST标记！        public JsonResult MyAjax(FormCollection f)        {            string val1 = f["val1"].ToString();            string val2 = f["val2"].ToString();            string val3 = f["val3"].ToString();            string val4 = f["val4"].ToString();            Student s = new Student()            {                stuNo = val1,                classId = val2,                name = val3            };            return Json(s);        }

2.直接传字符串：

$("#btn2").click(function () {            $.ajax({                type: 'POST',                url: "/Student/MyAjax2",                data: "val1=" + $("#txt1").val() + "&val2=" + $("#txt2").val() +                 "&val3=" + $("#txt3").val() + "&val4=" + $("#txt4").val(),                success: function (obj) { alert(obj); }            });        });

[HttpPost]        public ContentResult MyAjax2(FormCollection f)        {            string val1 = f["val1"].ToString();            string val2 = f["val2"].ToString();            string val3 = f["val3"].ToString();            string val4 = f["val4"].ToString();            string s = "";            s += val1 + ",";            s += val2 + ",";            s += val3 + ",";            s += val4 ;            return Content(s);        }
