Question

我有这个问题只发生在这个视图中，我不知道是什么原因。 jquery json发布没有向控制器发送任何数据，因为调试时很明显可以帮助我。这是代码

    $("#btConfirm").click(function () {
    //    alert(3);
        $.ajax({
            url: "@Url.Action("EmployeeDetails", "User")",
            type: 'Post',
            data: {
                "empID": $("#empID").val(),alert:("sending"),
                "countryID": $("#dropDown1").val(),
                "genderID": $("#dropDown2").val(),
                "ParentAccountID": $("#dropDown3").val(),
                "accountTypeID": $("#dropDown9").val(),
                "countryCode": $("#countryCode").val(),
                "addressJudiciary": $("#addressJudiciary").val(),
                "addressProvince": $("#addressProvince").val(),
                "addressCity": $("#addressCity").val(),
                "addressStreet": $("#addressStreet").val(),
                "addressBuilding": $("#addressBuilding").val(),
                "addressFloor": $("#addressFloor").val(),
                "addressDescription": $("#addressDescription").val(),
                "addressPhone1": $("#addressPhone1").val(),
                "addressPhone2": $("#addressPhone2").val(),
                "addressEmail": $("#addressEmail").val(),
                "personFName": $("#personFName").val(),
                "personMidName": $("#personMidName").val(),
                "personFamName": $("#personFamName").val(),
                "personMotherName": $("#personMotherName").val(),
                "personFullName": $("#personFullName").val(),
                "personBirthDate": $("#personBirthDate").val(),
                "accountKind": $("#accountKind").val(),
                "accountNumber": $("#accountNumber").val(),
                "accountName": $("#accountName").val(),
                "accountNetAmount": $("#accountNetAmount").val(),
                "empContractNumber": $("#empContractNumber").val(),
                "empIssueDate": $("#empIssueDate").val(),
                "empStartDate": $("#empStartDate").val(),
                "empEndDate": $("#empEndDate").val(),
                "empSalary": $("#empSalary").val(),
                "empHourRate": $("#empHourRate").val(),
                "empDamanNumber": $("#empDamanNumber").val(),
                "empDamanValue": $("#empDamanValue").val(),
                "empTransportation": $("#empTransportation").val()
            },
            dataType: 'json',
            error: function (xhr) {
                alert('Error: ' + xhr.statusText);
            },
            success: function (result) {
                alert(result);
                location.reload();
            }
        });

并且控制器的代码是

[HttpPost]
    public JsonResult EmployeeDetails(string cl)
    {
        try
        {
            string countryID = Request["countryID"];

我给你一个非常简单的例子来做你的问题，

PS：你的问题是你的班级没有足够的参数来捕捉来自Ajax的所有数据

前端代码

<script>
    //$("#btConfirm").click(function () {
        $.ajax({
            url: "@Url.Action("aaa" )",
            type: 'Post',
            data: {
                a: "1111",
                b: "1111"
                },
            dataType: 'json',
            error: function (xhr) {
                alert('Error: ' + xhr.statusText);
            },
            success: function (result) {
                alert(result);
                location.reload();
            }
        });
    //})
    </script>

后端代码

public JsonResult aaa(string a, string b)
        {
            return Json(new {  });
        }

PS：我将使用类来发送数据，如果我喜欢如下

namespace WebApplication5.Controllers
{
    public class HomeController : Controller
    {
        public ActionResult Index()
        {
            ViewBag.Title = "Home Page";

            return View();
        }

        public JsonResult aaa(string a, string b)
        {
            return Json(new {  });
        }

        public JsonResult aaa(SampleClass sc)
        {
            return Json(new { });
        }
    }


    public class SampleClass
    {
        public string a { get; set; }
        public string b { get; set; }
    }
}

Jquery Json Post不向控制器发送数据
