未将模型属性传递给剃刀视图

Question

我目前正在开发一个项目以模拟自行车存储。但是，我遇到了几个问题：

1.）出于某种原因，Order.Create中的名称未传递给Order。为什么是这样？ 2.）我希望Order.Create中的dropdownList通过JQuery从SelectList中的商店中删除任何Order。我将如何去做这件事？

代码如下。如果您有任何问题/文件要求/批评，请随时询问。

Order.Create：

<div class="form-group"> 
      @for(int i = 0; i < Model.Inventory.Count; i++) 
      { 
       <div class="col-md-10"> 
        @Html.HiddenFor(m => m.Inventory[i].Name) 
        @Html.HiddenFor(m => m.Inventory[i].Id) 
        @Html.HiddenFor(m => m.Inventory[i].Price) 
        @Html.CheckBoxFor(m => m.Inventory[i].IsSelected) 
        @Html.LabelFor(m => m.Inventory[i].IsSelected, Model.Inventory[i].Name) 
        @Html.DisplayFor(m => m.Inventory[i].Price) 
       </div> 
      } 
      <div class="col-md-10"> 
       @Html.LabelFor(m => m.Name) 
       @Html.TextBoxFor(m => m.Name) 
       @Html.LabelFor(m => m.PaymentMethod) 
       @Html.TextBoxFor(m => m.PaymentMethod) 
       @Html.LabelFor(model => model.StoreId, "StoreId", htmlAttributes: new { @class = "control-label col-md-2" }) 
       @Html.DropDownList("StoreId", null, htmlAttributes: new { @class = "form-control" }) 
       @Html.ValidationMessageFor(model => model.StoreId, "", new { @class = "text-danger" }) 
      </div> 
      </div>

Answer 1

1）你没有名称在[Bind(Include = "PaymentMethod, Inventory")]所以它是被排除在外。
