数据表 Ajax url 未命中控制器操作

Question

我有点沮丧，同样的代码在我的项目的其他地方也可以使用。由于某种原因，它没有击中控制器动作。当页面加载时，数据表出现并且只有处理弹出窗口，就像它找不到记录一样。我在控制器动作上放了一个断点，发现它甚至没有命中它。

Javascript 代码：

 $(document).ready(function () {
    var oTableMenuPermission = "";
    $("#PartsListTable").dataTable({
        "ajax": {
            "url": "/Home/GetList",
            "type": "POST",
            "datatype": "json",              
        },
        "responsive": true,
        "bRetrieve": true,
        "bProcessing": true,
        "deferRender": true,
        "dom": 'lBfrtip',
        "serverSide": "true",
        "order": [0, "PartNumber"],
        "language": {
            "processing": "processing...Please wait"
        },
        "buttons": [
            { extend: 'copyHtml5', exportOptions: { columns: ':visible' } }
            , { extend: 'excelHtml5', exportOptions: { columns: ':visible' } }
            , { extend: 'csvHtml5', exportOptions: { columns: ':visible' } }
            , { extend: 'pdfHtml5', exportOptions: { columns: ':visible' } }
            , { extend: 'print', exportOptions: { columns: ':visible' } }
            , 'colvis'
        ],
        columnDefs: [{ orderable: false, targets: [2, 3, 4, 5, 6] }],

        "aoColumns": [
            { "data": "PartNumber", "name": "PartNumber" },
            {
                "data": "PartImage", "aTargets": [0],
                "render": function (data) {
                    if (data === null) return '<img src=Content/Images/Parts/NoImage.png style="width:50px;" />';
                    return '<img src=Content/Images/Parts/' + data + ' class="zoom" style="width:50px;" />';
                }
            },
            { "data": "Description", "name": "Description" },             
            {
                "data": "HasUpgrade", "aTargets": [0],
                "render": function (data) {
                    if (data === true) {
                        return '<b style="color:green;">Yes</b>';
                    } else {
                        return '<b style="color:red;">No</b>';
                    }
                }
            },
            {
                "data": "IsUpgrade", "aTargets": [0],
                "render": function (data) {
                    if (data === true) {
                        return '<b style="color:green;">Yes</b>';
                    } else {
                        return '<b style="color:red;">No</b>';
                    }
                }
            },
            {
                "mRender": function (oObj, type, full) {
                    var button = '<div>'
                    button += '<div class="btn-group">';
                    button += '<a class="btn btn-warning btn-sm" href="' + ControlerNameParts + "/Details/" + full.Material + '" data-ajax-update="#SkEdit" data-ajax-success="openModalDialog(\'SkEdit\', \'Edit\')" data-ajax-mode="replace" data-ajax-method="GET" data-ajax-failure="clearModalDialog(\'SkEdit\');alert(\'Ajax call failed\')" data-ajax-begin="prepareModalDialog(\'SkEdit\')" data-ajax="true">Details</a>&nbsp;';
                    button += '</div></div>';
                    return button;
                }
            },

        ],


    });
});

这里是控制器动作：

        [HttpPost]
    public ActionResult GetList()
    {
        // Server Side Parameters
        int start = Convert.ToInt32(Request["start"]);
        int length = Convert.ToInt32(Request["length"]);
        string searchValue = Request["search[value]"];
        string sortColumnName = Request["column[" + Request["order[0][column]"] + "][name]"];
        string sortDirection = Request["order[0][dir]"];

        List<PartSearchView> prodList = new List<PartSearchView>();
        using (GeneralEntities db = new GeneralEntities())
        {
            prodList = db.PartSearchView.ToList();
            int totalRows = prodList.Count;
            if (!string.IsNullOrEmpty(searchValue))
            {
                prodList = prodList.Where(x => x.PartNumber != null && x.PartNumber.ToLower().Contains(searchValue.ToLower())).ToList();
            }

            int totalRowsAfterFilteing = prodList.Count;
            // Sorting
            prodList = prodList.OrderBy(sortColumnName + " " + sortDirection).ToList<PartSearchView>();

            prodList = prodList.Skip(start).Take(length).ToList();

            return Json(new { data = prodList, draw = Request["draw"], recordsTotal = totalRows, recordsFiltered = totalRowsAfterFilteing }, JsonRequestBehavior.AllowGet);
        }

    }

我已尝试将url 更改为@Url.Action("GetList", "Home")。

这可能与路由有关，但我在路由配置中看不到任何有问题的地方。 我尝试直接转到 URL，它会拉出一个 404 页面，这与正在运行的页面不同，它会出错但也会触发控制器操作。

感谢您的帮助！

更新： 以下是我的路线配置。我将页面名称和控制器操作更改为PartSearch，之前它只是Parts。还是同样的问题。这是 Home Controller 的一部分。

        );
    }

我更改了名称，因为我有一个 PartsController。 PartsController 用于后端，需要登录凭据。所以我不能用它来做这个。

更新：

我找到了我的问题。尽管这看起来很愚蠢，但它没有击中控制器的全部原因是因为在我有 columnDefs: [{ orderable: false, targets: [2, 3, 4, 5, 6] }], 的那一行中，可能有 1 列，有 6 列，但我忘记将第一列计为 0。我有过去在使用foreach 语句而不是server side 时发现了这一点，因为格式不会出现在加载时 - 意思是按钮、搜索、记录数等。但仍会填充记录。在server side 中，我猜它在记录生成之前出现故障。所以它根本与路由无关。而我得到的错误，我认为它与它没有任何关系，因为它说明了一些关于风格的东西。我在dataTables 论坛上找到了答案。感谢所有为此提供帮助的人。

您不需要 GetList 的发布操作，因为您不发送任何参数。删除 [post] 并仅用于测试尝试属性路由

在 IgnoreRoute 之后将此添加到您的配置中

 routes.IgnoreRoute("{resource}.axd/{*pathInfo}");

routes.MapMvcAttributeRoutes();

和控制器

[Route("~/home/getlist")]
public ActionResult GetList()

恕我直言，在 ajax 中将“type”：“POST”转为“GET”。
