如何将 JSON 数据与 Kendo Grid 绑定

Question

使用我的 WCF 服务我正在公开 JSON 数据：

 [OperationContract]
 [WebGet(ResponseFormat=WebMessageFormat.Json)]
 List<ProductDetails> GetProductDetails();

这里是返回的 JSON 示例：

{"d":[{"__type":"ProductDetails:#NWProducts","Discount":0,"OrderId":10248,"ProductId":11,"UnitPrice":14.0000,"quantity":12 },{"__type":"ProductDetails:#NWProducts","Discount":0,"OrderId":10248,"ProductId":42,"UnitPrice":9.8000,"quantity":10},{"__type": "ProductDetails:#NWProducts","Discount":0,"OrderId":10248,"ProductId":72,"UnitPrice":34.8000,"quantity":5},{"__type":"ProductDetails:#NWProducts", "Discount":0,"OrderId":10249,"ProductId":14,"UnitPrice":18.6000,"quantity":9},{"__type":"ProductDetails:#NWProducts","Discount":0," OrderId":10249,"ProductId":51,"UnitPrice":42.4000,"quantity":40}

尝试使用以下方法将其绑定到 Kendo Grid：

   <script>
                $(document).ready(function () {
                    $("#grid").kendoGrid({
                        dataSource: {
                            type: "json",
                            transport: {
                                read: "http://localhost/KendoServices/Web/GetProductDetails"
                            },
                            pageSize: 10
                        },
                        groupable: true,
                        sortable: true,
                        pageable: {
                            refresh: true,
                            pageSizes: true,
                            buttonCount: 5
                        },
                        columns: [{
                            field: "OrderId",
                            title: "OrderId",
                            width: 140
                        }, {
                            field: "ProductId",
                            title: "ProductId",
                            width: 190
                        }, {
                            field: "UnitPrice",
                            title: "UnitPrice"
                        }, {
                            field: "quanity",
                            width: 110
                        }]
                    });
                });
            </script>

由于某种原因，我无法在网格上看到任何数据。我尝试绑定数据的方式可能有问题。

Answer 1

生成的 JSON 是这里的罪魁祸首。默认情况下，kendo 数据源会查找返回对象以在名为 results 的数组中包含项目。很容易修复。只需要定义数据在响应 JSON 对象中的位置。

dataSource: {
    transport: {
        read: {
             url: "http://localhost/KendoServices/Web/GetProductDetails",
             dataType: 'json'
        }
    },
    pageSize: 10,
    schema: {
        data: function(response) {
            return response.d;
        }
    }
},

--编辑... 哎呀，漏掉了别的东西。您的 type: 'json' 应该在您的读取对象内，并且应该是 dataType: 'json'

试试这个

dataSource: {
    transport: {
            read: {
                   url: "http://localhost/KendoServices/Web/GetProductDetails",
                   contentType: 'application/json; charset=utf-8',
                   dataType: "json"
                  }
    },
    schema: {
                 data: "d"
            }
    }
}

这就是我的做法：

    $("#grid").kendoGrid({
        dataSource: {               
            transport: {
                    read: { 
                            url : pUrl,
                            dataType: "json"
                    }
            },
            pageSize:40,                
            schema: {
                data: function(response) {
                    return response.json;
                }
            }               

        },
        height: 550,
        groupable: false,
        sortable: true,
        pageable: {
            refresh: false,
            pageSizes: false,
            buttonCount: 5
        },
        columns: [
            {
                field: "SEQ_NO",
                title: "No",
                filterable: false,
                width: 120
            }, {
                field: "LOT_NO",
                title: "Lot No (INS' No)"
            }, {
                field: "TYPE",
                title: "INPUT (At 100% Burden)"
            }, {
                field: "ATTRIBUTE01",
                title: "1.0 In"
            }, {
                field: "ATTRIBUTE02",
                title: "2.0 In"
            }, {
                field: "ATTRIBUTE03",
                title: "0.05 In"
            }, {
                   field: "RESILT",
                   title: "RESILT"
            }
        ]
    });
