Question

以下代码在托管后无法在服务器上运行，但在localhost上运行正常。代码是否有任何问题。

控制器：

[HttpGet]
        public ActionResult SelectCustomerByID(Receipt model, string secondValue)
        {
            int CustID = 0;
            if (secondValue != null && secondValue != "")
                CustID = Convert.ToInt32(secondValue);
                ObservableCollection<Receipt> ReceiptList = new ObservableCollection<Receipt>();
                Receipt Receipt = new Models.Receipt();
                if (CustID != 0)
                    ReceiptList = Receipt.GetReceiptListByCustID(CustID);
                else
                   ReceiptList = Receipt.GetReceiptList();
                ViewData["Count"] = ReceiptList.Count;
                return PartialView("_Recepitgrid", ReceiptList);            
        }

部分视图中的脚本：

<script type="text/javascript">
    $(document).ready(function () {
        var str = ('@ViewData["Count"]');
        if (str == '0')
            ShowProduct();
        else
            ShowGrid();
    });

    function ShowProduct() {
        document.getElementById("gridContent").style.display = 'none';
        document.getElementById("ShowNodata").style.display = 'block';
        return false;
    }
    function ShowGrid() {
        document.getElementById("gridContent").style.display = 'block'; 
        document.getElementById("ShowNodata").style.display = 'none';
        return false;
    }

</script>

PartialView：

    <div id="divgrid" >
          @{  
           var grid = new WebGrid(Model, canPage: true, rowsPerPage: 5, selectionFieldName: "selectedRow", ajaxUpdateContainerId: "gridContent");
          grid.Pager(WebGridPagerModes.NextPrevious);}
          <div id="gridContent" class="rounded-corners">
           @grid.GetHtml(
           tableStyle: "webgrid-table",
           headerStyle: "webgrid-header",
           footerStyle: "webgrid-footer",
           alternatingRowStyle: "webgrid-alternating-row",
           selectedRowStyle: "webgrid-selected-row",
           rowStyle: "webgrid-row-style",
           columns: grid.Columns(
           grid.Column(header: "S.No", format: item => Item.WebGrid.Rows.IndexOf(item) + 1),
             grid.Column("Recepit_No", "Recepit Number", style: "PName"),
              grid.Column(null, null, format: @<input type="hidden" name="Id"  id="ID" value="@item.ID"/>),
             grid.Column("Cust_Name", "Cust Name", style: "PName"),
            grid.Column("Pay_Amount", "Paid Amount", style: "Curency"),
            grid.Column("Pay_Mode", "Paid Mode", style: "IName"),
            grid.Column("Bank_Name", "Bank Name", style: "Weight"),
             grid.Column("Bank_Address", " Bank Address", style: "MakingCharge"),
             grid.Column("ChequeNo", "ChequeNo", style: "Certification"),
              grid.Column("Cheque_Date", " Cheque Date", style: "Price"),
             grid.Column("Date", "Date", format: item => ((item.Date == null) ? "" : item.Date.ToString("dd/MM/yyyy")), style: "Price"),
              grid.Column("Edit", "", @<a href='../Admin/EditReceipt?Id=@item.Id' ><img src="~/Images/edit.png" alt='Edit' /></a>, style: "width:10%"),
             grid.Column(header: "Delete", format: @<text><a href="@Url.Action("DeleteReceipt", "Admin", new { Id = item.ID })" onclick="javascript:return confirm('Are you sure you'd like to delete this product?');"><img src="../Images/delete.png" alt='Delete' /></a></text>)
                                         ))

 </div>
</div>

（提供一系列选项作为答案，而不是变成一个巨大的评论垃圾邮件主题。）

听起来你的应用程序和逻辑很好，但是当你转向生产时，你可能会在不同的数据源上运行。

您在局部视图中对var str = ('@ViewData["Count"]');进行了引用。添加调试或警报以显示该值实际是什么。如果您发布的网站显示ViewData [“Count”] = 0，那么您的部分视图就是遵循您要告诉它的内容。

如果ViewData["Count"]中有有效号码，接下来要做的就是确认MODEL中的数据。尝试在网格之前的部分视图中包含一些临时调试语句，如下所示：

<span id="debugCheck1">is the model null? = @(Model==null)         </span>
<span id="debugCheck2">Model has this many rows? = @Model.Count  </span>
<div id="divgrid" >
      @{
      ..

最后，获取Firefox并安装firebug（或您选择的浏览器的任何webdeveloper工具）并使用NET面板检查显示404错误的任何请求。使用它来查看ajax请求并查看发送的实际结果。

祝你好运。
