Question

每次更新任何行时都会出现此错误。更新本身在数据库中是成功的，但是当我触发kendo的成功方法时，它似乎很困扰，在开始时我认为可能是我从数据库返回的对象是不同的，但它与我提交的那个。提前致谢

你为什么要在剑道内调用ajax？

应该像下面的代码一样。试试这个并更新状态，如果没有成功，我将修改代码。

dataSource = new kendo.data.DataSource({
    transport: {
        read:  {
            url: crudServiceBaseUrl + "?serviceType=students&serviceFunction=getStudentLists&type=2",
            dataType: "json",
            success: function (data) {
               console.log(data);
            }
        },
     update: {
           url: "/tools.php?id=ajaxstudentlist",
           dataType: "json",
           data:{inputParam:inputvalue},
           success: function(result) {
             console.log(data);
           }
     },
    parameterMap: function(options, operation) {
        if (operation !== "read" && options.models) {
           return {models: kendo.stringify(options.models)};
         }
       }
    },
   batch: true,
   pageSize: 20,
   schema: {
      model: {
           id: "studystatusid",
           fields: {
                studystatusid : { type: 'number', editable: false, nullable: true },
                studentid : { type: 'string', editable: false, nullable: false},
                lastname : { type: 'string', editable: false, },
                firstname : { type: 'string', editable: false, },
                spnumber : { type: 'string', editable: false, },
                status : { type: 'string', editable: false, },
                begin_date: { type: "date", validation: { required: true } },
                end_date: { type: "date" }
                }
            }
     }
});

您的数据源更新

 update: function(options) {
                    $.ajax( {
                        type: 'POST',
                        url: "/tools.php?id=ajaxstudentlist",
                        dataType: "json",
                        data: {data:options.data.models},
                        success: function(result) {
                            var arr = [];
                            arr.push(result);
                            var data = _.flatten(arr);
                            options.success();
                        }
                    });
                },

上面的ajax调用期待JSON结果返回，你应该返回一个JSON结果为成功，它更好地返回更新的行。
