我对Ajax表单有点问题。毫无疑问，我可能已经做了一点倒退。基本上，当我点击表单中的提交按钮时，什么也没发生。我已经调试但它似乎没有发布到action方法。它实际上什么都不做。
到目前为止，这是我的代码：
基本上我使用DetailedBreakdownReportRequest模型从表单发布信息。当我的页面显示初始未过滤结果列表时，此模型正在通过。
DetailedBreakdownReport行动方法：
[HttpPost]
public ActionResult DetailedBreakdownReport(DetailedBreakdownReportRequest reportRequest, FormCollection formVariables)
{
return View(reportRequest);
}
DetailedBreakdownReport View
<%@ Page Title="" Language="C#" MasterPageFile="~/Views/Shared/Main.Master" Inherits="System.Web.Mvc.ViewPage<MyApp.Data.AdvancedReports.AdvancedReports.DetailedBreakdownReports.DetailedBreakdownReportRequest>" %>
<asp:Content ID="Content1" ContentPlaceHolderID="TitleContent" runat="server">
Detailed Breakdown Report
</asp:Content>
<asp:Content ID="Content2" ContentPlaceHolderID="MainContent" runat="server">
<script language="javascript" type="text/javascript" src="<%= ResolveUrl("~/Scripts/jquery-1.4.1.min.js")%>"></script>
<script src="/Scripts/MicrosoftAjax.js" type="text/javascript"></script>

<% using (Ajax.BeginForm("DetailedList", "Reports",
new AjaxOptions
{
UpdateTargetId = "panelBreakdownList",
InsertionMode = InsertionMode.Replace
},
new { id = "SearchForm" })) %>
<% { %>
<div style="position: absolute; top: 0px; height: 30px; right: -12px; margin-top: 8px;
width: 250px; padding-left: 00px; vertical-align: middle; display: inline-block;">
<input id="searchField" name="searchField" style="padding-left: 5px; position: relative;

width: 200px;" />
<%: Html.HiddenFor(m => m.ToDate) %>
<%: Html.HiddenFor(m => m.FromDate) %>
<%: Html.HiddenFor(m => m.Currency) %>
<%: Html.HiddenFor(m => m.ReportType) %>
<!--<input type="image" src="/Content/Images/search-form-submit.png" style="border: 0px;

<input type="submit" value="Search" style="border: 0px;
height: 27px; position: relative; left: -8px; margin: 0x; float: left;" />
</div>
<% } %>
<div id="panelBreakdownList" style="position: relative; z-index: 0;">
<% Html.RenderAction("DetailedList", new { ToDate = Model.ToDate, FromDate = Model.FromDate, Currency = Model.Currency, ReportType = Model.ReportType }); %>
</div>
</asp:Content>
<asp:Content ID="Content4" ContentPlaceHolderID="Header" runat="server">
<h1>Detailed Breakdown Report</h1>
<h2><%: Model.ToDate.ToString("dd-MMM-yyyy") %> to <%: Model.FromDate.ToString("dd-MMM-yyyy")%></h2>
</asp:Content>
以下是从上一页调用的DetailedList操作，它是视图：
[HttpPost]
public ActionResult DetailedList(DateTime ToDate, DateTime FromDate, string Currency, string ReportType, FormCollection formVariables)
{
DetailedBreakdownReportRequest reportRequest = new DetailedBreakdownReportRequest()
{
ToDate = ToDate,
FromDate = FromDate,
Currency = Currency,
ReportType = ReportType,
UserId = UserServices.CurrentUserId
};
DrilldownReportEngine re = new DrilldownReportEngine();
DetailedBreakdownReport report = null;
if (formVariables.HasKeys())
{
reportRequest.searchTerm = formVariables["searchField"];
report = re.GetDetailedBreakdown(reportRequest);
}
else
{
report = re.GetDetailedBreakdown(reportRequest);
}
return PartialView(report);
}
<%@ Control Language="C#" Inherits="System.Web.Mvc.ViewUserControl<MyApp.Data.AdvancedReports.AdvancedReports.DetailedBreakdownReports.DetailedBreakdownReport>" %>
<% if (Model.HasData)
{ %>
<% if (Model.ShopBreakdown != null)
{ %>
<h2>Shop Breakdown Report</h2>
<p>Click on a shop's name to see additional information.</p>
<div id="shopGrid" style="float:left; width: 400px;">
<table width="400px">
<% foreach (var shop in Model.ShopBreakdown)
{ %>
<tr>
<td colspan="3"><h2><%: Html.ActionLink(shop.Shop.Name + " >>", "ShopDashboard", new { ShopId = shop.Shop.ShopID, Currency = Model.Currency, toDate = Model.ToDate.ToString(), fromDate = Model.FromDate.ToString(), percentageOfSales = shop.RevenuePercentageOfSales })%></h2></td>
</tr>
<tr>
<td><p class="labels">Units Sold:</p></td>
<td><b style="font-size:larger;"><%: shop.UnitsSoldPerShop%></b></td>
<td rowspan="2" align="center"><h2><%: String.Format("{0:0.0%}", shop.RevenuePercentageOfSales)%></h2> of Total Revenue</td>
</tr>
<tr>
<td><p class="labels">Revenue Earned:</p></td>
<td><b style="font-size:larger;"><%: String.Format("{0:0.00}", shop.TotalRevenuePerShop)%></b></td>
</tr>
<tr>
<td colspan="3"> </td>
</tr>
<% } %>
</table>
</div>
<% } %>
<% if (Model.ProductBreakdown != null)
{ %>
<% foreach (var product in Model.ProductBreakdown)
{ %>
<div id="ProductGrid" style="float:left; width: 500px;">
<div>
<h3><%: Html.ActionLink(product.Product.Name + " >>", "ProductDashboard", new { ProductId = product.Product.ProductID, Currency = Model.Currency, toDate = Model.ToDate.ToString(), fromDate = Model.FromDate.ToString(), percentageOfSales = product.RevenuePercentageOfSales })%></h3>
</div>
<div style="float:left; width: 200px;">
<p class="labels">Units Sold: </p><b style="font-size:larger;"><%: product.TotalUnitsSoldPerProduct %></b>
<br />
<p class="labels">Revenue Earned: </p><b style="font-size:larger;"><%: String.Format("{0:0.00}", product.OverallTotalRevenuePerProduct)%></b>
</div>
<div style="float: left; text-align: center;">
<h2><%: String.Format("{0:0.0%}", product.RevenuePercentageOfSales)%></h2> of Total Revenue
</div>
</div>
<% } %>
<div style="clear:both;" />
<br />
<% } %>
<% } %>
正如我上面所说，在第一次加载时，页面显示正常，它会显示未过滤的结果视图。当我在文本框中键入一个值并单击“提交”时，什么都没发生，我发现很难调试。至少如果它做了什么我会有一些工作。谁能看出我在这里做错了什么？
答案 0 :(得分：1)
正如我所看到的，你期望动作detailList中有一些不可为空的变量，这些变量可以从表单中获得。
[HttpPost]
public ActionResult DetailedList(DateTime ToDate, DateTime FromDate, string Currency, string ReportType, FormCollection formVariables)
{
......
}
但你只是在表单集合中发送searchfield。表格中的ToDate，FromDate，Currency变量在哪里？
我认为你应该创建一个formmodel例如
DetailedListSearchModel
DateTime ToDate
DateTime FromDate
string Currency
string ReportType
string Searchfield
并将搜索设为部分视图。只需在使用默认值呈现局部视图时传递默认值，然后以表格形式执行。
然后你会把这些值用在行动中 [HttpPost]
public ActionResult DetailedList(DetailedListSearchModel model)
{
......
}
您可以使用此模型，如
<%= Html.LabelFor(m => m.Searchfield) %>
<%= Html.TextBoxFor(m => m.Searchfield, new { @class = "css classes", maxlength = "1000" })%>
<%= Html.ValidationMessageFor(m => m.Searchfield) %>
$(function() {
$('form#SearchForm').find('a.submit-link').click( function() {
$('form#SearchForm').trigger('submit');
}).show();
}
并将搜索按钮更改为。
<a href="#" class="submit-link">Search</a>
