Question

在进行创建，更新或删除时，我需要保存其他表单并获取该保存功能的id，并将id作为附加参数传递给这些事件create, update, delete

怎么可以

我的网格脚本如下所示

 $(document).ready(function () {
                    var crudServiceBaseUrl = "https://demos.telerik.com/kendo-ui/service",
                        dataSource = new kendo.data.DataSource({
                            transport: {
                                read:  {
                                    url: crudServiceBaseUrl + "/Products",
                                    dataType: "jsonp"
                                },
                                update: {
                                    url: crudServiceBaseUrl + "/Products/Update",
                                    dataType: "jsonp"
                                },
                                destroy: {
                                    url: crudServiceBaseUrl + "/Products/Destroy",
                                    dataType: "jsonp"
                                },
                                create: {
                                    url: crudServiceBaseUrl + "/Products/Create",
                                    dataType: "jsonp"
                                },
                                parameterMap: function(options, operation) {
                                    if (operation !== "read" && options.models) {
                                        return {models: kendo.stringify(options.models)};
                                    }
                                }
                            },
                            batch: true,
                            pageSize: 20,
                            schema: {
                                model: {
                                    id: "ProductID",
                                    fields: {
                                        ProductID: { editable: false, nullable: true },
                                        ProductName: { validation: { required: true } },
                                        UnitPrice: { type: "number", validation: { required: true, min: 1} },
                                        Discontinued: { type: "boolean" },
                                        UnitsInStock: { type: "number", validation: { min: 0, required: true } }
                                    }
                                }
                            }
                        });

                    $("#grid").kendoGrid({
                        dataSource: dataSource,
                        pageable: true,
                        height: 550,
                        toolbar: ["create"],
                        columns: [
                            { field:"ProductName", title: "Product Name" },
                            { field: "UnitPrice", title:"Unit Price", format: "{0:c}", width: "120px" },
                            { field: "UnitsInStock", title:"Units In Stock", width: "120px" },
                            { field: "Discontinued", width: "120px" },
                            { command: ["edit", "destroy"], title: "&nbsp;", width: "250px" }],
                        editable: "popup"
                    });
                });

我发现了一些here，但这看起来并不正确

我需要将其发布到

 [HttpPost]
    public JsonResult Add(Product product, int categoryId)
    {

    }

Answer 1

只需在parameterMap内部将return语句更改为this，以便返回categoryId

return kendo.stringify({
    models: options.models, 
    categoryId: categoryIdFromSomewhere
)};

小注意，我使用JSON.stringify，但如果这会产生任何影响，那就太过分了。

创建，更新和删除时，Kendo UI会传递其他参数
