Asp.net 将输入文本中的值放入Html.BeginForm中的参数

我有Html.begin

@using (Html.BeginForm("AddMeals", "ClientReservations",new { overallCost= $('#mealsOverallCost').value }))

我读了下面的输入文本

<div id="DivMealsOverallCost">
            @Html.Label("Całkowity koszt", htmlAttributes: new { @class = "control-label col-md-2" })
            <input type="text" id="mealsOverallCost"  readonly="readonly" value="@ViewBag.OverallCost" />
        </div>

不正确。

您可以创建一个名称属性值为“overallCost”的隐藏输入表单元素，当您提交表单时，该元素将在请求正文中可用

@using (Html.BeginForm("AddMeals", "ClientReservations"))
{
   <input type="text" id="mealsOverallCost"  readonly="readonly" 
                                                 value="@ViewBag.OverallCost" />
   <input type="hidden" name="overallCost" value="@ViewBag.OverallCost" />

   <input type="submit" />
}

@使用（Html.BeginForm（“addfends”、“clientervations”））
{
}

@using (Html.BeginForm("AddMeals", "ClientReservations"))
{
   <input type="text" id="mealsOverallCost"  readonly="readonly" 
                                                 value="@ViewBag.OverallCost" />
   <input type="hidden" name="overallCost" value="@ViewBag.OverallCost" />

   <input type="submit" />
}
