Question

我正在一个项目中，用户可以上传评论，并且我想在用户上传数据的同一页面上显示所有上传的数据，我如何实现这一目标，请帮我解决这个问题的好方法是什么.i尝试了以下操作，但无法获得预期的结果

            public ActionResult Gandhiji(int? id)
            {
                ViewBag.Message = "150 Years Of Gandhiji";

                IEnumerable<UserComments> obj = db.UserComments;
                if(id!=null)
                {
                    obj = obj.Where(p => p.Id == id);
                }

                return View("Gandhiji",obj);
            }




                @model BigFoot.UsercommentsImage
                @using (Html.BeginForm("Gandhiji", "Home", FormMethod.Post, new { enctype = "multipart/form-data" }))

您可以返回json并将其绑定到任何控件，例如输入，标签或跨度。您需要更改return视图以返回json。

JQuery：

$(document).ready(function () {
    $("#InputDate").live('click', function () {
        var date = $("#InputDate").val();
        if (date != "") {
            $.getJSON("/Home/GetNames",
                    { date: $("#InputDate").val() },
                    function (data) {
                        $("#ProviderName").empty();
                        // [...]
                        });
                    });
        }
    });
});

和C＃

public JsonResult GetNames(string date)
 {
   List<Provider> list = new List<Provider>();
   // [...]
   return Json(list, JsonRequestBehavior.AllowGet);
}
