Question

我有一个下拉列表（可以选择多个选项）和另一个div中的两个输入框，其中包含id＆＃39; showInvestmentForm＆＃39;。选择下拉项目，我想生成这些文本关于所选下拉项数量的框。我希望这些文本框具有不同的名称，但我无法找到一种方法来为它们提供不同的名称，使其输入值传递给控制器。

这是我的控制器的一部分： -

foreach(var data in propertyViewModel.PropertyInvestors)
    {
    FounderInvestment founderInvestment = new FounderInvestment
    {
        Id = propertyViewModel.FounderInvestmentViewModel.Id ?? 0,
        InstallmentPeriod = propertyViewModel.FounderInvestmentViewModel.InstallmentPeriod,
        InvestorId = Convert.ToInt32(data),
        PropertyId = property.Id,
        Investment = propertyViewModel.FounderInvestmentViewModel.Investment
    };
    _founderInvestmentQueryProcessor.Create(founderInvestment);
}

这是我的下拉菜单： -

<div class="form-group">
  @Html.LabelFor(model => model.PropertyInvestors, htmlAttributes: new { @class = "control-label col-md-2" })
  <div class="col-md-10">
    @Html.DropDownListFor(model => model.PropertyInvestors, (IEnumerable<SelectListItem>)@ViewBag.Investors, "Select", htmlAttributes: new {@id="dropdown", @class = "form-control",@multiple="multiple" })
    @Html.ValidationMessageFor(model => model.PropertyInvestors, "", new { @class = "text-danger" })
  </div>
</div>

这些是文本框： -

<div id="showInvestmentForm" style="display:none">                        
    <div class="form-group">
    @Html.LabelFor(model => model.FounderInvestmentViewModel.Investment, htmlAttributes: new { @class = "control-label col-md-2" })
        <div class="col-md-10">
        @Html.EditorFor(model => model.FounderInvestmentViewModel.Investment, new { htmlAttributes = new { @class = "form-control" } })
        @Html.ValidationMessageFor(model => model.FounderInvestmentViewModel.Investment, "", new { @class = "text-danger" })
        </div>
    </div>
    <div class="form-group">
        @Html.LabelFor(model => model.FounderInvestmentViewModel.InstallmentPeriod, htmlAttributes: new { @class = "control-label col-md-2" })
        <div class="col-md-10">
            @Html.EditorFor(model => model.FounderInvestmentViewModel.InstallmentPeriod, new { htmlAttributes = new { @class = "form-control" } })
            @Html.ValidationMessageFor(model => model.FounderInvestmentViewModel.Investment, "", new { @class = "text-danger" })
        </div>
    </div>                       
</div>

如果我理解正确您的问题是输入文本没有发布到您的控制器。如果你编写Controller的代码来检查完整的场景，那将会很有用。

无论如何，当你使用Mvc助手时，一个常见的错误就是你的情况，当你指向一个嵌套属性时，生成的输入名称不是最终的属性名，而是该属性的路径。

@Html.EditorFor(model => model.FounderInvestmentViewModel.InstallmentPeriod, ..)

在您的情况下，代码生成名为FounderInvestmentViewModel_InstallmentPeriod的输入，而不仅仅是InstallmentPeriod。

如果在您的控制器中，您需要一个名为＆＃34; InstallmentPeriod＆＃34;的参数。不会收到，因为该页面发布了一个名为＆＃34; FounderInvestmentViewModel_InstallmentPeriod＆＃34;

的参数

如何生产＆＃39; n＆＃39;没有。具有不同名称的文本框相对于否。选择下拉项目？
