MVC从同一视图中的另一个表单获取值

短而“直”的问题:

控制器动作方法(A)由具有一些参数的表单调用。在同一个视图中,还有另一种形式,在提交时会在同一个控制器中调用另一个动作方法(B)。 如何从操作方法A访问(B)表单的值(但实际上它们是下拉列表和文本框的内容值)?

漫长而曲折的解释:

我有两种形式的视图,如下所示:

using (Html.BeginForm("List", "Rapporti"))
{
<span>Ricerca Rapporti per   Linea </span>

@Html.DropDownList("KLinea",
    new SelectList(new RapportiCT.Domain.Entities.RapportiEntities().TLinea, "KLinea", "DLinea")
    , "Scegli una linea");

<span>Data inizio</span>
@Html.TextBox("startDate", DateTime.Now.AddDays(-4).ToShortDateString(), new { @class = "dateTextBox" });                                                  

<span>Data fine</span>
@Html.TextBox("endDate", DateTime.Now.AddDays(-1).ToString("dd/MM/yyyy"), new { @class = "dateTextBox" })
<input type="submit" value="Cerca" />
}

if (Model.Count() > 0)
{
    var lastArticolo = "";
<h2>Rapporti Capoturno @Model.First().rapportoCT.DLinea</h2>
    <table>
    @foreach (var rapporto in Model)
    {
        if (lastArticolo != rapporto.rapportoCT.DCodArt)
        {
        <tr>
            <td class="td_title">
                @rapporto.rapportoCT.DCodArt
            </td>
            <td colspan="3" class="td_title">
                @rapporto.rapportoCT.DDescArt
            </td>
            <td class="td_title">
                Rendimento
            </td>
            <td class="td_title">
                #Pallet control.
            </td>
            <td class="td_title">
                #Pallet accanton.
            </td>
            <td class="td_title">
                Ore fermo linea
            </td>
        </tr>
            lastArticolo = rapporto.rapportoCT.DCodArt;
        }
        using (Html.BeginForm("ControlloQualita", "Rapporti"))
        {
        <tr>
            <td class="td_detail">
                @rapporto.rapportoCT.Data
            </td>
            <td class="td_detail">
                @rapporto.rapportoCT.Turno
            </td>
            <td class="td_detail">
                @rapporto.rapportoCT.Lettera
            </td>
            <td class="td_detail">
                @rapporto.rapportoCT.DNota
            </td>
            <td class="td_detail">
                @rapporto.RendimentoLinea
            </td>
            <td class="td_detail">
                @Html.TextBox("PalletControllati", rapporto.PalletControllati, new { style="width:50px" })
            </td>
            <td class="td_detail">
                @Html.TextBox("PalletAccantonati", rapporto.PalletAccantonati, new { style = "width:50px" })
            </td>
            <td class="td_detail">
                @Html.TextBox("OreFermoLinea", rapporto.OreFermoLinea, new { style = "width:50px" })
            </td>
            <td>
               <input type="submit" value="Salva" />
            </td>
        </tr>
        }
    }
</table>
}

else
{
@:Nessun record trovato
}

两个表单都发布到相同的 RapportiController :第一个表单用于查询数据库并显示结果记录,第二个表单用于更新数据库记录。

所以,我的Controller类是这样的:

// No problem here
public ViewResult List(int? KLinea = null, DateTime? startDate = null, DateTime? endDate = null)
    {
        IQueryable<VRapportiCT> qVRapporti = repository
                    .ViewRapporti(KLinea.Value, startDate.Value, endDate.Value);

        List<VRapportiCT> lRapporti = qVRapporti.ToList();

        List<RapportoRendimentoViewModel> listRRVM = new List<RapportoRendimentoViewModel>();
        foreach (var rapporto in lRapporti)
        {
            RapportoRendimentoViewModel rrVM = new RapportoRendimentoViewModel();
            rrVM.rapportoCT = rapporto;
            rrVM.RendimentoLinea = repository.GetRendimentoLinea(rapporto);
            rrVM.PalletControllati = "0";
            rrVM.PalletAccantonati = "0";
            rrVM.OreFermoLinea = "0";
            listRRVM.Add(rrVM);
        }

        return View(listRRVM);
    }

    public RedirectToRouteResult ControlloQualita(int PalletControllati, int PalletAccantonati, int OreFermoLinea)
    {
        // How can I access the 1°form values here (a.k.a. the DropDown and Date text box values?

        // ...Fake values, only to assert that the parameters get passed to the action...
        RouteValueDictionary dic = new RouteValueDictionary();
        dic.Add("KLinea", 55);
        dic.Add("startDate", DateTime.Now.AddDays(-4));
        dic.Add("endDate", DateTime.Now);

        return RedirectToAction("List", "Rapporti", dic);
    }

答案 0 :(得分:0)

我在这里看到两个选项:

  1. 将最后提交的“列表”表单存储在,例如Session,TempData或您喜欢的任何其他存储中,并在“ControlloQualita”表单提交中恢复这些值。此approch假定您需要从“列表”表单而不是最新提交的最后提交的值。

  2. 拦截“ControlloQualita”表单提交,以便将“List”表单的值附加到请求中。这可以通过在“ControlloQualita”表单中添加隐藏输入来实现。
