AJAX发布不击中控制器中的发布操作

Question

在这里，我尝试使用按钮onClick事件CreateException上的AJAX在AttorneyController的发布方法onclick="submitForm()"上发布表单。

现在的问题是，每当我单击按钮时，它都不会碰到CreateException的post方法AttorneyController并抛出错误POST http://localhost:58765/Attorney/CreateException 400 (Bad Request)。

对我的代码的任何帮助将深表感谢。谢谢

下面是我的ajax

<script>
function submitForm() {
    var datastring = $("#attorneyExceptionForm").serialize();
    var validForm = $("#attorneyExceptionForm").valid();
    if (!validForm) { return false; }

    $.ajax({
        type: "POST",
        url: "/Attorney/CreateException",
        data: datastring,           
        dataType: "json", 
        success: function (data) {
            if (data.success) {
                hideModalPopup();
                showNotification("Location saved successfully", "success");
            }
            else {
                showNotification("Failed to save the location", "warning");
            }
        },
        error: function (data) {
            debugger;
            showNotification("Failed to save the location", "warning");
        }
    });
}

以下是我的asp.net core 2.0表单

<form action="CreateException" role="form" enctype="multipart/form-data" id="attorneyExceptionForm">
@Html.HiddenFor(x => x.Id)
<div asp-validation-summary="ModelOnly" class="text-danger"></div>
<div class="form-group">
    <label asp-for="Description" class="control-label"></label>
    <input asp-for="Description" class="form-control" />
    <span asp-validation-for="Description" class="text-danger"></span>
</div>
<div class="form-group">
    <label asp-for="Entity" class="control-label"></label>
    <input asp-for="Entity" class="form-control" />
    <span asp-validation-for="Entity" class="text-danger"></span>
</div>
<div class="form-group">
    <label asp-for="Exception" class="control-label"></label>
    <input asp-for="Exception" class="form-control" />
    <span asp-validation-for="Exception" class="text-danger"></span>
</div>
<div class="form-group">
    <button type="button" onclick="submitForm()" class="btn btn-s-md btn-primary saveButton mb-10">Save</button>
</div>
</form>

以下是我的发帖方法

     [HttpPost]
    [ValidateAntiForgeryToken]
    public ActionResult CreateException(AttorneyViewModel attorneyVM)
    {
        try
        {
            if (attorneyVM != null)
            {
                if (attorneyVM.Status != "0")
                {
                    //var saveExceptionsResult = _attorneyService.SaveExcetion(attorneyVM);
                    return Json(new { success = _attorneyService.SaveExcetion(attorneyVM) });
                }
            }
            return Json(new { success = false });
        }
        catch (Exception ex)
        {
            return View();
        }
    }

下面是get方法

        public ActionResult CreateException(int Id = 0)
    {
        AttorneyViewModel attrVm = new AttorneyViewModel();
        //if (Id > 0)
        //{
        //    attrVm = _attorneyService.GetAttorneyById(Id);
        //}
        attrVm.Id = Id;
        List<exceptionStatus> exceptionsStatusList = new List<exceptionStatus>();
        exceptionsStatusList.Add(new exceptionStatus { Id = 1, ExceptionStatusName = "Active" });
        exceptionsStatusList.Add(new exceptionStatus { Id = 2, ExceptionStatusName = "Inactive" });
        exceptionsStatusList.Insert(0, new exceptionStatus { Id = 0, ExceptionStatusName = "Select Status" });
        ViewBag.AttorneyStatus = exceptionsStatusList;
        return PartialView("_CreateException",attrVm);
    }
