Question

单击提交按钮后，如何将当前项目ID和文本框值发送到控制器。：|

@model propertyMgmt.Models.Property
  <div class="container" id="tourpackages-carousel">
    <div class="panel panel-default" style="width:inherit">
      <div class="panel-heading">
        <h4 style="font-family:Tahoma, Geneva, sans-serif;margin-left:-5px;">
        <strong>@Model.PropertyDescription</strong></h4>
      </div>
      <div class="panel-body">
        <div class="row">
          <div class="col-md-6">
            <div>
              <img src="~/Image/@Model.PropertyImage" alt="" style="width:100%;height:300px">
            </div>
          </div>
          <div class="col-md-6" style="margin-left:-8px;margin-top:-20px;">
            <div style="background-color:#d9dadd">
              <h3 style="margin-left:16px;">
              <u>Property Details</u></h3>
            <dl class="dl-horizontal">
              <dt>Total Investment:</dt>
              <dd>@Model.InvestmentAmount</dd>
              <dt>Remaining Investment:</dt>
              <dd>@Model.RemainingInvestmentAmount</dd>
              <dt>Property Discription:</dt>
              <dd>@Model.PropertyDescription</dd>
              <dt>Property Cost:</dt>
              <dd>@Model.PropertyCost</dd>
              <dt>Country:</dt>
              <dd>@Model.Country</dd>
              <dt>City:</dt>
              <dd>@Model.City</dd>
            </dl>

            @using (Html.BeginForm("AddInvestment","Home",FormMethod.Post))
            {
            <input type="number" id="investmentAmount" name="investmentAmount" /><br />
            <input type="submit" value="Submit" />
            }
          </ div >
        </ div >
      </ div >
    </ div >
</ div >
</ div >

以下是具有所需参数的控制器。

[HttpPost]
        [Route("AddInvestment/{id}/{amount}")]
        public ActionResult AddInvestment(int propertyId, double investmentAmount)
        {
            Investment investment = new Investment();
            investment.PropertyId = propertyId;
            investment.InvestorId = Convert.ToInt32(Session["UserId"]);
            investment.InvestmentAmount = investmentAmount;
            _investmentQueryProcessor.AddInvestment(investment);
            RemainingInvestment(propertyId, investmentAmount);
            RemainingInvestorBalance(investment.InvestorId, investmentAmount);
            return View();
        }

我想了解如何使用帮助程序标记传递上述参数的项目ID和文本框值。我也不确定中间的@using html.beginform。：|任何帮助将不胜感激。

当您提交表单时（如您的代码所示），数据将作为键值对（名称：值）提交。这是使用输入控件的name属性完成的。如果你需要跟踪id，那么你需要将id放在它自己的＆＃34;键值对＆＃34; （在这种情况下，一个单独的输入控件）。像这样：

        @using (Html.BeginForm("AddInvestment","Home",FormMethod.Post))
        {
            <input type="number" id="investmentAmount" name="investmentAmount" /><br />
            <input type="hidden" id="propertyId" name="propertyId" value="@Model.PropertyId" /><br />
            <input type="submit" value="Submit" />
        }
