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);
switch (reportName.Code)
{
case "INTER":
return RedirectToAction("InterStats",
new
{
manufacturerId = manufacturerId,
countryId = countryId,
startDate = "2013-01-01",
endDate = "2013-01-31"
});
break;
case "CUMLEADS":
return RedirectToAction("LeadStats",
new
{
manufacturerId = manufacturerId,
countryId = countryId,
categoryId = categoryId,
startDate = startDate.ToString("yyyy-MM-dd"),
endDate = endDate.ToString("yyyy-MM-dd")
});
break;
case "IMP":
break;
}
return View();
}
/// </summary>
/// <returns></returns>
/// [JsonpFilter]
[AcceptVerbs(HttpVerbs.Get | HttpVerbs.Post)]
public ActionResult InterStats(int manufacturerId, int countryId, DateTime startDate, DateTime endDate)
{
//Get all manufacturerwidgets for manufacturer
var manufacturerWidget = _manufacturerWidgetsRepository.GetManufacturerWidgetByManufacturerAndCountry(manufacturerId, countryId);
var interReportJson = new InterReportJson();
var interRecordList = new List<InterRecord>(); // a list of my anonymous type without the relationships
interReportJson.InterRecordList = new List<InterRecord>();
var count = 1;
foreach (var mw in manufacturerWidget)
{
var widgetName = mw.Description;
//Get the product stats data
var imps = _productStatsRepository.GetSumImpressionsProductStatsForManufacturerCountryDate(
mw.Id, countryId, startDate, endDate);
var clicks = _productStatsRepository.GetSumClicksProductStatsForManufacturerCountryDate(
mw.Id, countryId, startDate, endDate);
float ctr = 0;
if (imps != 0 && clicks != 0)
{
ctr = ((clicks / (float)imps) * 100);
}
// Create the data for the report
var interRecord = new InterRecord
{
WidgetName = widgetName,
Impressions = imps,
Interactions = clicks,
Ctr = ctr,
Count = count
};
interReportJson.InterRecordList.Add(interRecord);
count++;
}
interReportJson.Counter = count;
return PartialView(interReportJson);
}
目前没有＆lt;％Html.RenderPartial（“InterStats”）; ％GT;我的部分是在一个新窗口中打开，并且由于没有数据，因为在提交表单之后没有数据。而且它可能不是部分“InterStats”它可能是部分“LeadsStats”
修改
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 countryId = $("#countryId > 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;
alert(theUrl);
$.ajax({
type: "POST",
//contentType: "application/json; charset=utf-8",
url: theUrl,
data: { 'manufacturerId': manufacturerId, 'countryId': countryId, 'startDate': startDate, 'endDate': endDate },
dataType: "json",
success: function (data) {
//see this http://stackoverflow.com/questions/11472947/how-to-format-my-json-data-for-stack-column-chart-in-highcharts
var widgetNameArray = [];
var impressionsArray = [];
var intsArray = [];
for (var i = 0; i < data.length; i++) {
var item1 = data[i];
//only display on graph if not 0
if (item1.Impressions > 0) {
var widgetCategories = item1.WidgetName;
//put into an array
widgetNameArray.push(widgetCategories);
var imps = item1.Impressions;
impressionsArray.push(imps);
var ints = item1.Interactions;
intsArray.push(ints);
}
}
// Create the chart
$('#container').highcharts({
chart: {
type: 'column'
},
title: {
text: 'Inter Chart ' + startDate + ' to ' + endDate
},
xAxis: {
categories: widgetNameArray,
labels: {
rotation: -45,
align: 'right',
style: {
fontSize: '13px',
fontFamily: 'Verdana, sans-serif'
}
}
},
yAxis: {
min: 0,
title: {
text: 'Impressions/Interactions'
},
stackLabels: {
enabled: false,
style: {
fontWeight: 'bold',
color: (Highcharts.theme && Highcharts.theme.textColor) || 'gray'
}
}
},
legend: {
align: 'right',
x: -100,
verticalAlign: 'top',
y: 20,
floating: true,
backgroundColor: (Highcharts.theme && Highcharts.theme.legendBackgroundColorSolid) || 'white',
borderColor: '#CCC',
borderWidth: 1,
shadow: false
},
tooltip: {
formatter: function () {
return '<b>' + this.x + '</b><br/>' +
this.series.name + ': ' + this.y + '<br/>';
}
},
plotOptions: {
bar: {
dataLabels: {
enabled: true
}
}
},
series: [{
name: 'Impressions',
data: impressionsArray
}, {
name: 'Interactions',
data: intsArray
}]
});
var table = document.getElementById("usertable");
var tabledata = "";
tabledata += "<tr>";
tabledata += "<th>Widget Name</th>";
tabledata += "<th>Impressions</th>";
tabledata += "<th>Interactions</th>";
tabledata += "<th>CTR</th>";
tabledata += "</tr>";
for (var i = 0; i < data.length; i++) {
var item = data[i];
tabledata += "<tr>";
tabledata += "<td>" + item.WidgetName + "</td>";
tabledata += "<td>" + item.Impressions + "</td>";
tabledata += "<td>" + item.Interactions + "</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/格式的格式因报告而异，因此我根据报告ID分别显示如何显示它们。
我希望很清楚我需要做什么，请问是否。
谢谢！

您需要调用AJAX方法并传递必要的数据才能完成所需的响应。你可以做GET或POST。在GET上放置查询字符串上的键值对，用于POST主体中的post put键值对。你可以看到jQuery AJAX文档。 看起来您必须为您的代码执行AJAX或回发，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，对不起，我不清楚我需要做什么。
我实际上想要根据用户从下拉列表中选择的报告选择部分视图。
所以在视图中我使用了.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>
在控制器中我放了一个案例陈述，所以我知道我在哪个报告：
//我们在这里解析哪个部分会被看到哪个报告（因此将触发ajax调用......
switch (report.Code)
{
case "INTER":
ViewData["InterStats"] = true;
break;
case "CUMLEADS":
ViewData["CumLeadsStats"] = true;
break;
}
并且在视图中我使用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东西，但它似乎有效。
