@using WebSearch.EFDB;

@{

    ViewBag.Title = "UploadFeeCertificate";

    NoveltyProxy proxy = ViewData["Proxy"] as NoveltyProxy;

}

                                <p><input type="button" id="submitPic" class="btn btn-w-m btn-success" value="提交" /></p>

                            </div>

                    </form>

                </div>

            </div>

        </div>

    </div>

    <script type="text/javascript">

        $(function () {

            $("#submitPic").click(function () {

                $("#editform").ajaxSubmit({

                    url: "../FeeHistory/AjaxUploadFee",

                    success: function (data) {

                        var t = $.parseJSON(data);

                        if (t.Result == true) {

                            alert("上传成功！");

                            location.href = "../NoveltyProxy/ProxyManage"

                        } else {

                            alert("上传失败！");

                        }

                    }

                });

            })

        });

    </script>

</body>

</html>

2.后端代码：

 /// <summary>

        /// AJAX提交上传收费凭据form

        /// </summary>

        /// <returns></returns>

        public string AjaxUploadFee()

        {

            RoleUser login = System.Web.HttpContext.Current.Session["Login"] as RoleUser;

            FeeHistory model = new FeeHistory();

            model.Addtime = DateTime.Now;

            model.AddUserId = login.ID;

            model.AddUserName = login.UserName;

            model.ProxyID = Request.Form["proxyid"];

            model.AdminChecked = false;

            HttpPostedFileBase uploadFile = Request.Files["lefile"] as HttpPostedFileBase;

            if (uploadFile != null)

            {

                int last = uploadFile.FileName.LastIndexOf(".");

                string name = uploadFile.FileName.Substring(last, uploadFile.FileName.Length - last);

                string docxname = "缴费说明" + DateTime.Now.ToString("yyyyMMddHHmmss") + name;

                string pathForSaving = Server.MapPath("~/Word/JFSM/" + docxname);

                uploadFile.SaveAs(pathForSaving);

                if (System.IO.File.Exists(pathForSaving))

                {

                    model.ImgUrl = "../Word/JFSM/" + docxname;

                }

            }

            bool result = Fls.AddFeeHistory(model);

            string Msg = "";

            var Mod = new

            {

                Result = result,

                Msg = Msg

            };

            string json = JsonConvert.SerializeObject(Mod);

            return json;

        }

注意。

 Request.Form[]是根据控件的Name获取的，并不是ID。jq用久了可能会遗忘这个事情。
