Asp.Net MVC Ajax 表单未发布到操作
本文关键字:操作 表单 Net MVC Ajax Asp | 更新日期: 2023-09-27 18:35:38
我在使用Ajax表单时遇到了一些问题。毫无疑问,我可能做得有点倒退了。基本上,当我点击表单中的提交按钮时,什么也没发生。我已经调试过,但它似乎没有发布到操作方法。它实际上什么都不做。
这是我到目前为止的代码:
基本上,我从具有DetailedBreakdownReportRequest模型的表单中发布信息。此模型正在正常通过,因为我的页面显示初始未过滤结果的列表。
详细细分报告操作方法:
[HttpPost]
public ActionResult DetailedBreakdownReport(DetailedBreakdownReportRequest reportRequest, FormCollection formVariables)
{
return View(reportRequest);
}

下面是从上页调用的 DetailedList 操作及其视图:
[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)

<% } %>

</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="clear:both;" />
<br />
<% } %>
<% } %>
正如我上面所说,在第一次加载时,页面显示正常,它显示结果的未过滤视图。当我在文本框中输入值并单击提交时,什么也没发生,我发现很难调试。至少如果它做了一些事情,我会有一些东西可以处理。谁能看出我在这里做错了什么?
如我所见,您希望在操作 detailedList 中有一些不可为空的变量,这些变量是表单中期望的。
[HttpPost]
public ActionResult DetailedList(DateTime ToDate, DateTime FromDate, string Currency, string ReportType, FormCollection formVariables)
{
......
}
但是您只需在表单集合中发送搜索字段。表单中的"日期"、"开始日期"、"货币"变量在哪里?
我认为您应该创建一个表单模型例如
DetailedListSearchModel
DateTime ToDate
DateTime FromDate
string Currency
string ReportType
string Searchfield
并将搜索设置为局部视图。当使用默认值呈现部分视图时,只需传递默认值,然后在表单中执行。
然后,您将在操作中采用此值,例如[维基邮报]
public ActionResult DetailedList(DetailedListSearchModel model)
{
......
}
您可以在以下形式中使用此模型
<%= 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。
<a href="#" class="submit-link">Search</a>
