Question

我想在mvc 4中获取DDL值时出现500内部错误它会运行，并给我类似波纹管的产品ID，但不会向我显示Porduct详细信息： http://localhost:24494/Merchant/GetProduct?id=14

控制者：

[HttpGet]
public PartialViewResult GetProduct(int id)
{
    ProductRepository BlProduct = new ProductRepository();
    var model = BlProduct.Find(id);
    return PartialView("_CampProductPartialView", model);
}

部分：

@model CrazyAvocado.ViewModels.Merchant.AddCampaignViewModel

<div class="display-field">
    @Html.DisplayFor(model => model.Product.Name)
</div>

<div class="display-label">
     @Html.DisplayNameFor(model => model.Product.Price)
</div>

视图：

@using (Html.BeginForm("AddCampaign", "Merchant", FormMethod.Post, new { enctype = "multipart/form-data", id = "myUploadForm" }))

下拉列表：

@Html.DropDownListFor(x => Model.Campaign.Productid, new SelectList(Model.Products, "id", "Name"), htmlAttributes: new { @class = "form-control", id = "ProductsDDL" })

包含该内容的细分应该显示详细信息： Div ID为“ divPartialView”

 @Html.Partial("_CampProductPartialView")

最后是Jquery脚本

<script>
  $("#ProductsDDL").change(function (event) {
      var ProductId = $(this).val();
      $.ajax({
          url: "@Url.Action("GetProduct", "Merchant")",
          data: { id: ProductId },
          type: "Get",
          dataType: "html",
          success: function (data) {
              //Whatever result you have got from your controller with html partial view replace with a specific html.
              $("#divPartialView").html(data); // HTML DOM replace
          }
      });
  });
</script>

基于下拉选择MVC 4的显示值
