如何根据控制器渲染局部视图？

所以..我需要根据已发布的值呈现部分视图：

  <script type="text/javascript" language="javascript">
      $(document).ready(function () {
                            $("#GetReport").click(function () {
                                $("form[name=StatsForm]").submit();

                            });
                        });
  </script>



<% Html.RenderPartial("InterStats"); %> //this is wrong i need it to render the partial depending on selection and only after the  $("#GetReport").click

控制器：

 /// <summary>
        /// POST /Stats/Index
        /// </summary>
        /// <param name="form"></param>
        /// <returns></returns>
        [AcceptVerbs(HttpVerbs.Post)]
        public ActionResult Index(FormCollection form)
        {
            // Deal with the form 
            var manufacturerId = Convert.ToInt32(form["manufacturerId"]);
            var reportId = Convert.ToInt32(form["reportId"]);
            var categoryId = Convert.ToInt32(form["categoryId"]);
            var retailerId = Convert.ToInt32(form["retailerId"]);
            var countryId = Convert.ToInt32(form["countryId"]);
            var regionId = Convert.ToInt32(form["regionId"]);
            var manufacturerWidgetId = (form["ManufacturerWidgetId"]);
            var startDate = new DateTime(1, 1, 1, 0, 0, 0, 0);
            var endDate = new DateTime(1, 1, 1, 0, 0, 0, 0);    

            var reportName = _reportRepository.GetReport(reportId);

        interReportJson.Counter = count;




        return PartialView(interReportJson);
    }

目前没有 <% Html.RenderPartial("InterStats"); %> 我的部分正在一个新窗口中打开，并且它失败了，因为在提交表单之前没有数据。而且它可能不是部分“InterStats”，它可能是部分“LeadsStats”

我正在使用 AJAX 执行以下操作：

 <script type="text/javascript">

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


                var manufacturerId = $("#manufacturerId > option:selected").attr("value");

                var startDate = $("#startDate").val();
                var endDate = $("#endDate").val();

                //var manufacturerId = 241;
                //var countryId = 230;
                //                 var startDate = '2013-01-01';
                //                 var endDate = '2013-01-31';

                var theUrl = "/ProductStats/Parameters/" + manufacturerId + "/" + countryId + "/" + startDate + "/" + endDate;

                        });




                        var table = document.getElementById("usertable");

                        tabledata += "<th>Interactions</th>";
                        tabledata += "<th>CTR</th>";

                        for (var i = 0; i < data.length; i++) {

                            var item = data[i];

                            tabledata += "<tr>";
                            tabledata += "<td>" + item.WidgetName + "</td>";

                            tabledata += "<td>" + item.Ctr.toFixed(2) + "%</td>";
                            tabledata += "</tr>";

                        }


                        table.innerHTML = tabledata;

                        $("th").css("background-color", "#3399FF");
                        $("tr:even").css("background-color", "#eeeeee");
                        $("tr:odd").css("background-color", "#ffffff");


                    }
                }
                 );


            });

        </script>

但这仅适用于其中一个报告，因为表格/chrt 的格式因报告而异，因此需要根据报告 ID 分别显示它们的方式。

我希望很清楚我需要做什么，如果没有，请询​​问。

谢谢！

您要么需要调用 AJAX 方法并传入必要的数据，以便它能够完成所需的响应。您可以执行 GET 或 POST。在 GET 上将键值对放在查询字符串上，对于 post 将键值对放在 POST 正文中。您可以查看 jQuery AJAX 文档。 看起来您必须执行 AJAX 或回发才能使您的代码正常工作，因为它需要用户输入。

我建议像...

<div id="reportDiv">
   <!-- dynamic content will be populated here after user makes some selection, etc.. -->
</div>

<script type="text/javascript">
   $(document).ready(function () {
      $("#GetReport").click(function () {
         if (selectionDictatesThatReportBeShown) {
            // Make AJAX call and put response html in the reportDiv
            $('#reportDiv').load('/SomeController/SomeAction?key1=value1&key2=value2');
         }

         // optionally do this?
         $("form[name=StatsForm]").submit();
      });
   });
</script>

感谢 Sam 的意见，很抱歉我不清楚我需要做什么。

我实际上想根据用户从下拉列表中选择的报告来选择部分视图。

因此，在视图中，我使用了 .change 以便我们知道何时选择了报告：

<script type="text/javascript">
        //<![CDATA[

     $(function () {

         $("#selectReport").hide();
         var manufacturerId;

         $("select#manufacturerId").change(function () {
             manufacturerId = $("#manufacturerId > option:selected").attr("value");
             $("#selectReport").show();

         });


         $("select#reportId").change(function () {
             var reportId = $("#reportId > option:selected").attr("value");

             var theUrl = "/ReportStats/GetReport/" + reportId + "/" + manufacturerId;

             $.ajax({
                 url: theUrl,
                 success: function (data) {
                     $('#ajaxOptionalFields').html(data);
                 },
                 error: function () {
                     alert("an error occured here");
                 }
             });
         });
     });

        //]]>
    </script>

在控制器中，我放置了一个案例声明，以便我知道我在哪个报告中：

//这里我们决定哪个部分将被看到哪个报告（所以哪个ajax调用将被触发......

 switch (report.Code)
            {
                case "INTER":
                    ViewData["InterStats"] = true;
                    break;
                case "CUMLEADS":
                    ViewData["CumLeadsStats"] = true;
                    break;
            }

并且在视图中我使用了一个 if 语句来决定将显示哪个报告部分：

<% if (Convert.ToBoolean(ViewData["InterStats"]))
   { %>
<% Html.RenderPartial("InterReport"); %>
<% }
   else if (Convert.ToBoolean(ViewData["CumLeadsStats"]))
   { %>
<% Html.RenderPartial("CummulativeReport"); %>
<% }  %>

我不确定这是否是一种非常糟糕的方式来做我需要的事情，但它似乎有效。
