Kendo-UI 调度程序 'GetTimezoneOffset' 错误

Question

要开始使用 Kendo UI 处理日历，我首先从 Salesforce 组织中提取事件并在日程表上显示它们。但是，我被“无法读取属性 'getTimezoneOffset' 的未定义错误所困扰，正在寻求帮助。我的 JS 是：

var data = '{!jsonString}';
       var scheduler = $('#scheduler').kendoScheduler({
       date: new Date(),
       startTime: new Date(),
       height: 700,
       timezone: "Etc/UTC",
       views: [
          {type: "week", selected: true},
          "week",
          "month",
          "agenda"
       ],
       dataSource: {
          batch: true,
          transport: {
              read: function(e){
                  console.log(data);
                  e.success(data);
              },
              update: {
                  url: "http://demos.telerik.com/kendo-ui/service/tasks/update",
                  dataType: "jsonp"
              },
              create: {
                  url: "http://demos.telerik.com/kendo-ui/service/tasks/create",
                  dataType: "jsonp"
              },
              destroy: {
                  url: "http://demos.telerik.com/kendo-ui/service/tasks/destroy",
                  dataType: "jsonp"
              },
              parameterMap: function(options, operation) {
                  if (operation !== "read" && options.models) {
                      return {models: kendo.stringify(options.models)};
                  }
              }
          },
          schema: {
              model: {
                  id: "OwnerId",
                  fields: {
                       taskId: { from: "TaskID" },
                       title: { from: "Title", defaultValue: "No title", validation: { required: true } },
                       start: { type: "date", from: "Start" },
                       end: { type: "date", from: "EndTime" },
                       startTimezone: { from: "StartTimezone" },
                       endTimezone: { from: "EndTimezone" },
                       description: { from: "Description" },
                       recurrenceId: { from: "RecurrenceID" },
                       recurrenceRule: { from: "RecurrenceRule" },
                       recurrenceException: { from: "RecurrenceException" },
                       ownerId: { from: "OwnerID", defaultValue: 1 },
                       isAllDay: { type: "boolean", from: "IsAllDay" }
                  }
              }
          }
      }
                        //});
  });

数据变量JSON格式为：

[{"Title":"meeting","TaskId":"00U410000059ZjbEAE","StartTimezone":"Etc/UTC","Start":"2017-01-26", "RecurrenceRule":null, "RecurrenceId":null, "RecurrenceException":null, "OwnerId":"005410000020eLnAAI", "IsAllDay":false, "EndTimezone":"Etc/UTC", "End":"2017-01-26", "Description":"a meeting"},{"Title":"meeting", "TaskId":"00U410000059ZjcEAE", "StartTimezone":"Etc/UTC", "Start":"2017-01-26", "RecurrenceRule":null, "RecurrenceId":null, "RecurrenceException":null, "OwnerId":"005410000020eU9AAI", "IsAllDay":false, "EndTimezone":"Etc/UTC", "End":"2017-01-26", "Description":"a meeting"}, etc...}]

根据读取操作中的console.log(data)。我有一个控制器获取事件数组，然后 JSON.serializes 该数组（这是 JSON 字符串，数据访问）。

我不明白时区偏移的问题是什么，我所有的 JSON 条目数据都与教程模式的字段相匹配，但它仍然不起作用...我只需要日历通过将此 JSON 传递给读取操作来显示打开时当前存在的所有事件。任何帮助将不胜感激！谢谢。

这是我的控制器：

global with sharing class CalendarData {

public List<Event> eventList{get;set;}
public String jsonString{get;set;}
public List<schedulerItem> correctedItems{get;set;}

public CalendarData(){
    String eventQuery = 'SELECT ActivityDate,ActivityDateTime,CreatedById,Description,DurationInMinutes,EventSubtype,IsAllDayEvent,Location,OwnerId,EndDateTime,StartDateTime,Subject FROM Event';
    eventList = Database.query(eventQuery);
    correctedItems = itemList(eventList);
    system.debug(correctedItems);
    jsonString = JSON.serialize(correctedItems);
    jsonString = jsonString.replace('"EndTime"', '"End"');
}

public List<schedulerItem> itemList(List<Event> events){
        Integer i = 0;
        system.debug(events);
        List<schedulerItem> kendoEvents = new List<schedulerItem>();
        schedulerItem item = new schedulerItem();
        for(i = 0; i < events.size(); i++){
            item.Description = events[i].Description;
            Datetime dt = events[i].EndDateTime;
            item.EndTime = dt.date();
            dt = events[i].StartDateTime;
            item.Start = dt.date();
            item.EndTimezone = 'Etc/UTC';
    //public String id;
            item.IsAllDay = events[i].IsAllDayEvent;
            item.RecurrenceException = null; 
            item.RecurrenceId = null;
            item.RecurrenceRule = null;
            item.StartTimezone = 'Etc/UTC';
            item.Title = events[i].Subject;
            item.TaskId = events[i].Id;
            item.OwnerId = events[i].OwnerId;
            system.debug(item);
            kendoEvents.add(item);

            item = new schedulerItem();
        }
        return kendoEvents;
    }

public class schedulerItem{
    public String Description;
    public Date EndTime;
    public Date Start;
    public String EndTimezone;
    //public String id;
    public Boolean IsAllDay;
    public String RecurrenceException; 
    public String RecurrenceId;
    public String RecurrenceRule;
    public String StartTimezone;
    public String Title;
    public String TaskId;
    public String OwnerId;

}
}

我得到一个事件列表，然后使用自定义 class 创建一个新列表以将原始事件列表中的数据绑定到数据名称与教程中的架构模型名称匹配的事件。我还将所有 "EndTime" 替换为 "End."

找到读取我的事件的解决方案：

var data = '{!jsonString}';
                var dataList = JSON.parse(data);
                function getNewEvents() {
                    var eventList = [];
                    for(var i = 0; i < dataList.length; i++){
                        //console.log("DataList Again: " + dataList[i]);
                        var kendoEvent = new kendo.data.SchedulerEvent({
                            id: i,
                            taskId: dataList[i].TaskId,
                            title: dataList[i].Title,
                            start: new Date(dataList[i].Start),
                            end: new Date(dataList[i].End),
                            startTimezone: dataList[i].StartTimezone,
                            endTimezone: dataList[i].EndTimezone,
                            description: dataList[i].Description,
                            recurrenceId: dataList[i].RecurrenceId,
                            recurrenceRule: dataList[i].RecurrenceRule,
                            recurrenceException: dataList[i].RecurrenceException,
                            ownerId: dataList[i].OwnerId,
                            isAllDay: dataList[i].IsAllDay
                        });
                        eventList.push(kendoEvent);
                    }
                    return eventList;
                }
                eventData = getNewEvents();

我获取返回的 JSON 数组，然后将其解析回对象数组，然后创建一个新的实际 kendo.data.SchedulerEvents 数组并用正确的名称填充所有字段。然后在数据源中的读取操作中，我没有使用 URL 和数据类型，而是：

read: function(e){
    e.success(data);
}

其中数据是我的 kendo 调度程序事件数组。现在，我的日程表显示了我组织中的所有事件。现在我需要处理更新、销毁和创建操作 :)。已接受答案的评论中提供的链接帮助我通过必要的文档找到了这个解决方案。

Answer 1

这个问题可能还有其他原因，正如我在评论中提到的，但查看代码的错误之一是 模型配置不正确以及读取配置不正确

JSON 中没有输入字段 EndTime 而是 End.

将 EndTime 更改为 End 将字段声明与传入 JSON

匹配

{"Title":"meeting","IsAllDay":false,"EndTimezone":"Etc/UTC","End":"2017-01-26", "Description":"a meeting"}

这是字段声明

    fields: {
                           taskId: { from: "TaskID" },
                           title: { from: "Title", defaultValue: "No title", validation: { required: true } },
                           start: { type: "date", from: "Start" },
 // problem was here there is no EndTime as mentioned in the given code sample above .
// changed to End as it is in the incoming JSON
                           end: { type: "date", from: "End" },
                           startTimezone: { from: "StartTimezone" },
                           endTimezone: { from: "EndTimezone" },
                           description: { from: "Description" },
                           recurrenceId: { from: "RecurrenceID" },
                           recurrenceRule: { from: "RecurrenceRule" },
                           recurrenceException: { from: "RecurrenceException" },
                           ownerId: { from: "OwnerID", defaultValue: 1 },
                           isAllDay: { type: "boolean", from: "IsAllDay" }
                      }

有关详细信息，请参阅 telerik 网站上的这个基本示例。
