Kendo Grid Object不支持属性或方法’slice’

我试图将kendo网格绑定到WCF远程odata服务。 但是当我尝试填充网格时，我收到exception对象不支持属性或方法’slice’ 。 这是我填充网格的javascript代码。

$("#datagrid").kendoGrid({ dataSource: { type: "json", transport: { read: "http://localhost:65401/sdrservice.svc/IssueLists" }, pageSize: 20 }, groupable: true, sortable: true, pageable: { refresh: true, pageSizes: true, buttonCount: 3 }, columns: [{ field: "Issueid" }, { field: "Subject" }, { field: "Description" }, { field: "Module" }, { field: "Status" }, { field: "StartDate" }, { field: "ClosureDate", nullable: true }, { field: "RaisedBy" }, { field: "Duration" }] }); 

而我的json对象就像

  {"odata.metadata":"http://localhost:65401/sdrservice.svc/$metadata#IssueLists", "value":[{"Issueid":"512","Subject":"Crossing","Description":"a feugiat et eros vestibulum ac est lacinia nisi venenatis tristique fusce congue diam id ornare imperdiet","Module":"ADF","Status":"Fixed","StartDate":"2013-05-14T00:00:00","ClosureDate":null,"RaisedBy":"Azhar Husain","Duration":828}, {"Issueid":"474","Subject":"Point","Description":"a feugiat et eros vestibulum ac est lacinia nisi venenatis tristique fusce congue diam id ornare imperdiet sapien urna","Module":"ADF","Status":"Open","StartDate":"2012-10-09T00:00:00","ClosureDate":null,"RaisedBy":"Azhar Husain","Duration":1045}, {"Issueid":"937","Subject":"Point","Description":"a ipsum integer a nibh in quis justo maecenas rhoncus aliquam lacus morbi","Module":"TM1","Status":"Fixed","StartDate":"2013-05-31T00:00:00","ClosureDate":null,"RaisedBy":"Azhar Husain","Duration":811}, {"Issueid":"226","Subject":"Point","Description":"a libero nam dui proin leo odio porttitor id consequat in consequat","Module":"DATA MINING","Status":"Open","StartDate":"2014-11-08T00:00:00","ClosureDate":null,"RaisedBy":"Azhar Husain","Duration":285}, {"Issueid":"76","Subject":"Hill","Description":"a libero nam dui proin leo odio porttitor id consequat in consequat ut nulla sed","Module":"TM1","Status":"Fixed","StartDate":"2013-04-12T00:00:00","ClosureDate":null,"RaisedBy":"Azhar Husain","Duration":860}]} 

我认为问题是json对象作为切片方法需要数组，这里是data.value但是如何使用它是我的问题，因为方法中的读取行直接调用服务并执行我无法控制的所需任务。

Answer 1

您需要设置dataSource的schema.data属性。

 schema: { data: 'value' } 

文档http://docs.telerik.com/kendo-ui/api/javascript/data/datasource#configuration-schema.data

Answer 2

您需要在配置中设置schema ，因为您没有将数据源直接绑定到返回的对象，而是实际上绑定到该对象中的属性（即value属性）。

尝试像这样设置数据源：

 dataSource: { type: "json", transport: { read: "http://localhost:65401/sdrservice.svc/IssueLists" }, pageSize: 20, schema: { data: function(response) { return response.value; } } }
