jquery 的 Telerik Kendo 网格不显示数据

Question

我的 kendo 网格定义如下：

var dataSource = new kendo.data.DataSource({
batch: false,
autoSync: true,
transport: {
    read: {
        url: "/monitoring/matrix/routecontentrules?format=json",
        contentType: "application/json; charset=utf-8",
        dataType: "json",
        type: "POST",
        timeout: 30000
    },
    update: {
        url: "/monitoring/matrix/routecontentrules/updateroutecontentrule",
        contentType: "application/json; charset=utf-8",
        dataType: "json",
        type: "PUT"
    },
    create: {
        url: "/monitoring/matrix/routecontentrules/createroutecontentrule",
        contentType: "application/json; charset=utf-8",
        dataType: "json",
        type: "POST"
    },
    destroy: {
        url: "/monitoring/matrix/routecontentrules/deleteroutecontentrule",
        contentType: "application/json; charset=utf-8",
        dataType: "json",
        type: "DELETE"
    },
    parameterMap: function (data, operation) {
        if (operation == "read") {
            return kendo.stringify({
                RouteId: routeDataItem.RouteId
            });
        }
        else if (operation == "destroy") {
            return kendo.stringify({
                Id: data.Id,
            });
        }
        else {
            return kendo.stringify({
                Id: data.Id,
                RouteId: routeDataItem.RouteId,
                OrderId: data.OrderId,
                SenderMatch: data.SenderMatch,
                ContentMatch: data.ContentMatch,
                SenderReplace: data.SenderReplace,
                ContentReplace: data.ContentReplace,
            });
        }
    }
},
schema: {
    model: {
        id: "Id",
        fields: {
            Id: { type: "number", defaultValue: 0 },
            OrderId: { type: "number", defaultValue: 0 },
            SenderMatch: { type: "string", defaultValue: "" },
            ContentMatch: { type: "string", defaultValue: "" },
            SenderReplace: { type: "string", defaultValue: "" },
            ContentReplace: { type: "string", defaultValue: "" }
        }
    }
}});$("#Grid").kendoGrid({
dataSource: dataSource,
reorderable: false,
resizable: false,
sortable: false,
groupable: false,
scrollable: true,
navigatable: true,
editable: true,
columns: [
    {
        width: 150, field: "SenderMatch", title: "Sender match",
        template: "<span><label class='SenderMatch'</label></span>",
        headerAttributes: { title: "Sender match", style: "text-align: right" }, attributes: { style: "text-align: right" }
    },
    {
        width: 150, field: "ContentMatch", title: "Content match",
        template: "<span><label class='SenderMatch'</label></span>",
        headerAttributes: { title: "Content match", style: "text-align: right" }, attributes: { style: "text-align: right" }
    },
    {
        width: 150, field: "SenderReplace", title: "Sender replace",
        template: "<span><label class='SenderMatch'</label></span>",
        headerAttributes: { title: "Sender replace", style: "text-align: right" }, attributes: { style: "text-align: right" }
    },
    {
        width: 150, field: "ContentReplace", title: "Content replace",
        template: "<span><label class='SenderMatch'</label></span>",
        headerAttributes: { title: "Content replace", style: "text-align: right" }, attributes: { style: "text-align: right" }
    },
    {
        command: [
            { name: "destroy", template: "<a class='k-button k-grid-delete delete'><span class='k-sprite px-sprite px-i-sm-trash'></span></a>" }
        ],
        width: "50px"
    }
],
toolbar: kendo.template('<span class="ReloadManipulationByCustomer" style=""><span class="k-icon k-i-refresh refresh-btn"></span></span><a class="k-button k-grid-add add-btn" href="javascript:void(0)"><span class="k-sprite px-sprite px-i-sm-new new" />Add</a>')});$(".ReloadManipulationByCustomer").click(function () {
$("#Grid").data("kendoGrid").dataSource.read();});

后端我使用的是ServiceStack，请求定义如下：

    [Route("/monitoring/matrix/routecontentrules/createroutecontentrule", "POST")]
[Route("/monitoring/matrix/routecontentrules/updateroutecontentrule", "PUT")]
public sealed class CreateUpdateRouteContentRuleRequest
{
    public int Id { get; set; }
 
    public int OrderId { get; set; }
 
    public int RouteId { get; set; }
 
    public string SenderMatch { get; set; }
 
    public string ContentMatch { get; set; }
 
    public string SenderReplace { get; set; }
 
    public string ContentReplace { get; set; }
}
 
[Route("/monitoring/matrix/routecontentrules")]
public sealed class RouteContentRulesRequest
{
    public int RouteId { get; set; }
}
 
[Route("/monitoring/matrix/routecontentrules/deleteroutecontentrule")]
public sealed class DeleteRouteContentRuleRequest
{
    public int Id { get; set; }
}
 
public sealed class RouteContentRuleModel
{
    public int Id { get; set; }
 
    public int OrderId { get; set; }
 
    public int RouteId { get; set; }
 
    public string SenderMatch { get; set; }
 
    public string ContentMatch { get; set; }
 
    public string SenderReplace { get; set; }
 
    public string ContentReplace { get; set; }
}

获取数据代码如下：

    public object Post(RouteContentRulesRequest request)
{
    return _dbConnectionFactory
        .OpenReadOnlyAndRun(dbConn => dbConn.Select<RouteContentRule>(r => r.RouteId == request.RouteId).OrderBy(r => r.OrderId));
}

public object Any(CreateUpdateRouteContentRuleRequest request)
{
    RouteContentRule entity;

    if (!Db.Exists<Route>(new { Id = request.RouteId }))
    {
        throw new HttpError(HttpStatusCode.BadRequest, $"Route with id {request.RouteId} does not exist");
    }
    if (request.Id != 0)
    {
        var routeContentRule = _dbConnectionFactory.OpenReadOnlyAndRun(dbConn => dbConn.SingleById<RouteContentRule>(request.Id));
        entity = request.ToEntity(routeContentRule);
        Db.Update(entity, r => r.Id == routeContentRule.Id);
        return entity.ToModel();
    }

    entity = request.ToEntity();
    entity.OrderId = (_dbConnectionFactory.OpenReadOnlyAndRun(dbConn => dbConn.Scalar<RouteContentRule, int?>(x => Sql.Max(x.OrderId), x => x.RouteId == request.RouteId)) ?? 0) + 1;
    var id = (int)Db.Insert(entity, true);
    entity.Id = id;

    return entity.ToModel();
}

public void Delete(DeleteRouteContentRuleRequest request)
{
    Db.Delete<RouteContentRule>(new {Id = request.Id});
}

读取请求中的数据如下：

    [
   {
      "Id":35,
      "OrderId":1,
      "RouteId":72303,
      "SenderMatch":"335",
      "ContentMatch":"",
      "SenderReplace":"",
      "ContentReplace":""
   },
   {
      "Id":36,
      "OrderId":2,
      "RouteId":72303,
      "SenderMatch":"55",
      "ContentMatch":"",
      "SenderReplace":"",
      "ContentReplace":""
   }
]

以下是来自 Chrome 开发者工具的图像：

问题是网格没有显示这些数据。如果我点击网格单元格，我可以看到数据在这里。在这种情况下，该单元格变为可编辑状态，并显示数据的当前值。但是一旦我将编辑移动到一些新的单元格之前隐藏数据。我正在检查单元格，我发现当单元格未编辑时，它描述如下：

    <td style="text-align: right" aria-describedby="50349c08-da61-49d2-aa73-9c0823d4a4a4" role="gridcell">
    <span><label class="SenderMatch" <="" label=""></label></span>
</td>

当单元处于edding模式时，html中描述如下：

<td style="text-align: right" aria-describedby="ccc2df23-b49a-4b00-820a-02a67c428a52" role="gridcell" id="Grid_active_cell" class="k-edit-cell" data-role="editable">
    <input type="text" class="k-input k-textbox" name="SenderMatch" data-bind="value:SenderMatch">
</td>

我不知道为什么没有显示数据。据我所知，它应该显示数据，但它没有显示这些数据。

Answer 1

为什么要在 class 上添加 [Route] 属性......？它们应该在 Controller 的 Action.

上

然后你可以打开Chrome的开发工具，查看network选项卡，查看数据是否发送到back-end。

你可以把network的图片贴出来给我们看看你觉得应该拿数据的时候，我们可以看看是什么问题。

Answer 2

我知道问题出在哪里了。

columns: [
{
    width: 150, field: "SenderMatch", title: "Sender match",
    template: "<span><label class='SenderMatch'</label></span>",
    headerAttributes: { title: "Sender match", style: "text-align: right" }, attributes: { style: "text-align: right" }
},
{
    width: 150, field: "ContentMatch", title: "Content match",
    template: "<span><label class='SenderMatch'</label></span>",
    headerAttributes: { title: "Content match", style: "text-align: right" }, attributes: { style: "text-align: right" }
},
{
    width: 150, field: "SenderReplace", title: "Sender replace",
    template: "<span><label class='SenderMatch'</label></span>",
    headerAttributes: { title: "Sender replace", style: "text-align: right" }, attributes: { style: "text-align: right" }
},
{
    width: 150, field: "ContentReplace", title: "Content replace",
    template: "<span><label class='SenderMatch'</label></span>",
    headerAttributes: { title: "Content replace", style: "text-align: right" }, attributes: { style: "text-align: right" }
},
{
    command: [
        { name: "destroy", template: "<a class='k-button k-grid-delete delete'><span class='k-sprite px-sprite px-i-sm-trash'></span></a>" }
    ],
    width: "50px"
}],

模板有问题。我删除了它们，现在显示了数据。命令模板仍然有效。
