我创建了一个表格形式的项目表，每个表格旁边都有用于订购的按钮。对于每个项目，我希望用户在提交之前指定数量。单击订购按钮后，我需要该项目以及要发送到控制器post方法的数量参数，在该方法中，我将该数据发送到Sql Server进行操作（我已经用Sql编写了存储过程）。我在弄清楚如何从视图中将ItemId和InputQty发送到控制器post方法时遇到了麻烦。
//型号
public class USA
{
[Key]
public int ItemId { get; set; }
public int PlanSeqId { get; set; }
public string ItemDescription { get; set; }
public int OrderQuantity { get; set; }
public int OrderSldTdy { get; set; }
public int PlannedMinutesQty { get; set; }
public int ActualMinutesQty { get; set; }
public int NetworkId { get; set; }
public int CompanyId { get; set; }
public int AvaiForSaleQty { get; set; }
[DataType(DataType.Date)]
public DateTime ShowDate { get; set; }
public string ShowCd { get; set; }
[NotMapped]
public int InputQty { get; set; }
}
}
//控制器
private readonly OrderContext _context;
public USAsController(OrderContext context)
{
_context = context;
}
// GET: USAs
public async Task<IActionResult> Index()
{
return View(await _context.USA.ToListAsync());
}
[HttpPost]
public IActionResult Order(USA usa)
{
string path = Directory.GetCurrentDirectory();
var builder = new ConfigurationBuilder()
.SetBasePath(path)
.AddJsonFile("appsettings.json", optional: false, reloadOnChange: true);
IConfiguration config = builder.Build();
string sqlConnectionString = config.GetConnectionString("OrderContext");
string sql = "OrderItemUpdate";
if (usa.AvaiForSaleQty != 0 && usa.AvaiForSaleQty - usa.OrderQuantity >= 0)
{
using (var connection = new SqlConnection(sqlConnectionString))
{
try
{
connection.Open();
DynamicParameters parameter = new DynamicParameters();
parameter.Add("@CompanyId", usa.CompanyId, DbType.Int32, ParameterDirection.Input);
parameter.Add("@ItemId", usa.ItemId, DbType.Int32, ParameterDirection.Input);
parameter.Add("@PlanSeqId", usa.PlanSeqId, DbType.Int32, ParameterDirection.Input);

parameter.Add("@ShowDate", usa.ShowDate, DbType.String, ParameterDirection.Input);
parameter.Add("@ShowCd", usa.ShowCd, DbType.String, ParameterDirection.Input);
connection.Execute(sql, parameter, commandType: CommandType.StoredProcedure);
return RedirectToAction(nameof(Index));
}
catch (SqlException ex)
{
Console.WriteLine(ex.Message);
}
connection.Close();
}
return View();
}
else
{
ViewBag.Message("Inventory too low for amount ordered.");
return View();
}
}

有没有一种方法可以不使用jQuery？我并不反对，但是我觉得好像有一种简单的方法，就是我没有看到使用HTML / C＃。预先感谢。

似乎您只想将单个实体发布到服务器端，可以修改以下代码：
@model List<QxHOrderSystem.Models.USA>
<table class="table">
<thead>
<tr>
<th></th>
<th>
ItemId
</th>
<th>
ItemDescription
</th>
<th>
Order Quantity
</th>
<th>
AvaiForSaleQty
</th>
<th></th>
</tr>
</thead>
<tbody>
@for (int i = 0; i < Model.Count(); i++)
{
using (Html.BeginForm("Order", "Home", FormMethod.Post))
{
<tr>
<td>
<input type="submit" value="Order" />
</td>
<td>
@Html.DisplayFor(modelItem => Model[i].ItemId)
<input type="hidden" value="@Model[i].ItemId" name="ItemId"/>
</td>
<td>
@Html.DisplayFor(modelItem => Model[i].ItemDescription)
</td>
<td>
@Html.EditorFor(model => Model[i].InputQty, null, "InputQty")
</td>
<td>
@Html.DisplayFor(modelItem => Model[i].AvaiForSaleQty)
</td>
<td>
<a asp-action="Edit" asp-route-id="@Model[i].ItemId">Edit</a> |
<a asp-action="Details" asp-route-id="@Model[i].ItemId">Details</a> |
<a asp-action="Delete" asp-route-id="@Model[i].ItemId">Delete</a>
</td>
</tr>
}
}
</tbody>
在服务器端：
public IActionResult Order(USA usa)
{
.....
}
当点击ItemId按钮时，它将发送InputQty和Order。
