Google Apps脚本：event.setTime错误和时间格式

问题描述

我正在创建一个几乎完整的预订系统。目前，我正在从表单中收集数据，并将其传递给工作表，然后使用其中一些信息创建日历事件。这一切都正常。

在创建事件时，我还收集eventID，以便我可以使用它识别事件并从电子表格中更新事件。这些更新也在起作用，除了更新导致以下错误的开始/结束日期和时间外：

TypeError：在对象CalendarEventSeries中找不到函数setTime

这是我正在使用的代码：

  var eventStart = sh.getRange（D+ rowNumber）.getValues（）; 
 var eventEnd = sh.getRange（E+ rowNumber）.getValues（）; 
 event.setTime（eventStart，eventEnd）; 
  

我用setLocation和setTitle完成同样的事情，没有问题。

我是新手，我不知道对象是什么，所以错误信息对我来说意义非常小！但是我可以看到，setTime是类CalendarEvent中列出的一种方法（），但不在CalendarEventSeries中。我的所有事件都是开关事件吗？

感谢您提供任何指示。

UPDATE

我已经集成了Mogsdad的高级日历服务代码，并且在
$ b $ <$ b $ <$ c $之后c>var endTime = parseDate（event.end.date || event.end.dateTime）;

我正在检查/日志记录'startTime'和'event'。 'startTime'会以'无效日期'的形式回来（坏事？），'event'会回来，我可以想象所有的日历条目信息（我希望的好东西？！）。

parseDate函数应该放在哪里？也许我把它放在了错误的地方（我已经试过了所有的地方！），这不被使用？

另外，现在我想要的事件编辑已确定，解析的日期和用于搜索我已经找到的事件，以便返回一个日历事件，我最终可以使用setTime？这是完整的吗？

感谢您的支持。

更新2 - 无效日期？

如果我跳过解析并记录变量，如下所示：

var startTime = event.start.dateTime;

结果是2015-05-24T02：00：00 + 01：00，我认为这是现实。所以无效日期肯定是在解析函数期间发生错误的一种情况，因为它只是在它返回无效日期。

下面的代码。

  function onOpen（）{
 var ss = SpreadsheetApp.getActiveSpreadsheet（）; 
 var menuEntries = [{name：手动创建事件文档，functionName：addSheet}，{name：更新日历条目，functionName：getEventById} 
]; 
 
 
 ss.addMenu（Select Row& Click Here，menuEntries）; 
}

 var parts = string.split（ 'T'）;

解决方案

Serge的说法正确 - 问题在于您已经检索了对象，而不是。由于服务中唯一会按ID查找事件的方法是，你有点卡住了。

一种选择是使用改为：

  var event = Calendar.Events.get（calendarId，eventId）; 
  

对于新代码，这是一个不错的选择，特别是对于已经习惯了JavaScript API的开发人员。如果您是初学者或者不熟悉高级服务，那么您会发现学习曲线比日历服务更陡峭。 在这种情况下，这些实用程序应该帮助您坚持使用CalendarApp及其类和方法，通过填充 getEventById（）函数。

高级日历服务

有两个版本的 getEventById（）。第一个使用高级日历服务，必须在使用之前。

I'm creating something of a booking system which is nearly complete. Currently I'm collecting data from a form, passing it to a sheet, and then using some of that info to create a calendar event. This all works fine.

On creating the event, I'm also collecting the eventID so that I can use it to identify the event and update it from the spreadsheet. These updates are also working, with the exception of updating the start/end date and time which causes the following error:

TypeError: Cannot find function setTime in object CalendarEventSeries.

This is the code I'm working with:

var eventStart =  sh.getRange("D"+rowNumber).getValues();
var eventEnd =  sh.getRange("E"+rowNumber).getValues();
event.setTime(eventStart, eventEnd);

I'm doing exactly the same thing with setLocation and setTitle without a problem.

I'm new to this, I don't know what an object is and so the error message means very little to me! But I can see that setTime is a method outlined in the class 'CalendarEvent' (https://developers.google.com/apps-script/reference/calendar/calendar-event#setTime(Date,Date)), but not in 'CalendarEventSeries'. All my events are on-off events anyway?

Thanks in advance for any pointers.

UPDATE

I have integrated Mogsdad's Advanced Calendar Service code, and after

"var endTime = parseDate(event.end.date||event.end.dateTime);"

I am checking/logging 'startTime' and 'event'. 'startTime' is coming back as 'invalid date' (bad thing?) and 'event' is coming back with all the calendar entry info I can imagine (good thing I hope?!).

Where should the parseDate function actually go? Maybe I have it in the wrong place (I've tried it all over the place!) and this isn't being used?

Also, now the event I want to edit has been identified, are the dates parsed and used to search for the event I have already found in order to return a Calendar event that I can ultimately use setTime on? Is that the whole point of this?

Thanks for bearing with me.

UPDATE 2 - INVALID DATE?

If I skip the parsing and log the variable like this:

var startTime = event.start.dateTime;

The result is 2015-05-24T02:00:00+01:00 which I think is spot on. So the invalid date is definitely a case of something going wrong during the parse function as it only then that it returns 'invalid date'.

Code in context below.

function onOpen() {
  var ss = SpreadsheetApp.getActiveSpreadsheet();
  var menuEntries = [{name: "Create Event Document Manually", functionName: "addSheet"},{name: "Update Calendar Entry", functionName: "getEventById"}
  ];


  ss.addMenu("Select Row & Click Here", menuEntries);
}

 *

 * @param {string} eventId      Event ID to match
 *
 * @returns {CalendarEvent}     CalendarApp CalendarEvent object or null
 */


function getEventById(calendarId, eventId) {

  var ss = SpreadsheetApp.getActiveSpreadsheet();
  var sh = ss.getActiveSheet();
  var rowNumber = sh.getActiveRange().getRowIndex();
  var myEventId = "q8q533oioluipirksmno88qv2g";
  var calendarId = "[email protected]";


  // Get event by ID.
  var event = Calendar.Events.get(calendarId, myEventId);
  // This isn't a CalendarApp CalendarEvent though, so use the info
  // in the event to find it AGAIN as the right type.




  // Get start & end times of event. All-day events start at start.date,
  // while other events start at start.datetime. Likewise for end.

  var startTime = parseDate(event.start.date||event.start.dateTime);
  var endTime = parseDate(event.end.date||event.end.dateTime);



   Logger.log('Variables: ' + startTime + ' and ' + endTime);

  // Get array of events that fall between startTime & endTime
  var calEvents = CalendarApp.getEvents(startTime, endTime);

  // Search through those events, looking for a match by ID
  for (var i=0; i<calEvents.length; i++) {
    var curId = calEvents[i].getId().split('@')[0];  // extract id from [email protected]
    if (curId == eventId) {
      // Mission accomplished; we have an Event object with given id!
      return calEvents[i];

    }
  }
  // We did not find matching event
  return null;


}




  function parseDate(string) {
  var parts = string.split('T');
  parts[0] = parts[0].replace(/-/g, '/');
  return new Date(parts.join(' '));
}

解决方案

Serge has it right - the problem is that you've retrieved a CalendarEventSeries object, not a CalendarEvent. Since the only method in the service that will look for an event by ID is getEventSeriesById(iCalId), you're kinda stuck.

One option is to use the Advanced Calendar Service instead:

var event = Calendar.Events.get(calendarId, eventId);

For new code, that's a great option, especially for developers already used to Javascript APIs. If you're a beginner or not familiar with the Advanced Services, though, you'll find that there's a steeper learning curve than for the Calendar Service.

In that case, these utilities should help you stick with the CalendarApp and its Classes and Methods, by filling the need for a getEventById() function.

Advanced Calendar Service under the hood

There are two versions of getEventById(). This first one utilizes the Advanced Calendar Service, which must be enabled before use. The code is fairly straight-forward. You must provide the Calendar ID explicitly, since this isn't a Class Method. Example:

var calendarId = CalendarApp.getDefaultCalendar().getId();
var eventId = "smmd8h1dfe9lo9bip52hidnqk0";
var event = getEventById(calendarId, eventId);

Code:

/**
 * Retrieve a CalendarApp CalendarEvent object from IDs.
 * This version utilizes the Advanced Calendar Service, which must be
 * enabled before use.
 *
 * @param {string} calendarId   ID of calendar to be searched
 * @param {string} eventId      Event ID to match
 *
 * @returns {CalendarEvent}     CalendarApp CalendarEvent object or null
 */
function getEventById(calendarId, eventId) {
  // Get event by ID.
  var event = Calendar.Events.get(calendarId, eventId);
  // This isn't a CalendarApp CalendarEvent though, so use the info
  // in the event to find it AGAIN as the right type.

  // Get start & end times of event. All-day events start at start.date,
  // while other events start at start.datetime. Likewise for end.
  var startTime = parseDate(event.start.date||event.start.dateTime);
  var endTime = parseDate(event.end.date||event.end.dateTime);

  // Get array of events that fall between startTime & endTime
  var calEvents = CalendarApp.getEvents(startTime, endTime);

  // Search through those events, looking for a match by ID
  for (var i=0; i<calEvents.length; i++) {
    var curId = calEvents[i].getId().split('@')[0];  // extract id from [email protected]
    if (curId == eventId) {
      // Mission accomplished; we have an Event object with given id!
      return calEvents[i];
    }
  }
  // We did not find matching event
  return null;
}

Calendar API via UrlFetchApp

This version utilizes the Calendar API via UrlFetchApp, which doesn't require any special enablement. However, the code is more complex than the previous version.

/**
 * Retrieve a CalendarApp CalendarEvent object from IDs.
 * This version utilizes the Calendar API via UrlFetchApp, so
 * requires no enablement. However, it's more complex.
 *
 * @param {string} calendarId   ID of calendar to be searched
 * @param {string} eventId      Event ID to match
 *
 * @returns {CalendarEvent}     CalendarApp CalendarEvent object or null
 */
function getEventById(calendarId, eventId) {
  // Prepare a GET request to API URL, to Get event by ID.
  var url = "https://www.googleapis.com/calendar/v3/calendars/calendarId/events/eventId"
            .replace("calendarId",calendarId)
            .replace("eventId",eventId);

  var options = {
    headers: {
      'Authorization': 'Bearer ' +  ScriptApp.getOAuthToken()
    }
  }

  // Send request
  var response = UrlFetchApp.fetch(url, options);
  var rc = response.getResponseCode();
  var text = response.getContentText();

  // If result code is 200OK, process response text
  if (rc == 200) {
    // The event is contained in the response text; parse it into an object
    var event = JSON.parse(text);
    // This isn't a CalendarApp CalendarEvent though, so use the info
    // in the event to find it AGAIN as the right type.

    // Get start & end times of event. All-day events start at start.date,
    // while other events start at start.datetime. Likewise for end.
    var startTime = parseDate(event.start.date||event.start.dateTime);
    var endTime = parseDate(event.end.date||event.end.dateTime);

    // Get array of events that fall between startTime & endTime
    var calEvents = CalendarApp.getEvents(startTime, endTime);

    // Search through those events, looking for a match by ID
    for (var i=0; i<calEvents.length; i++) {
      var curId = calEvents[i].getId().split('@')[0];  // extract id from [email protected]
      var desc = calEvents[i].getDescription();
      if (curId == eventId) {
        // Mission accomplished; we have an Event object with given id!
        return calEvents[i];
      }
    }
    // We did not find matching event
    return null;
  }
  else
    // An error in fetch, anything BUT 200
    throw new Error( ""+rc+JSON.parse(text).message );
}

Helper function

Both versions of getEventById() require this helper function, provided in Google's documentation.

/**
 * From https://developers.google.com/apps-script/advanced/calendar#listing_events
 *
 * Parses an RFC 3339 date or datetime string and returns a corresponding Date
 * object. This function is provided as a workaround until Apps Script properly
 * supports RFC 3339 dates. For more information, see

 * @param {string} string The RFC 3339 string to parse.
 * @return {Date} The parsed date.
 */
function parseDate(string) {
  var parts = string.split('T');
  parts[0] = parts[0].replace(/-/g, '/');
  return new Date(parts.join(' '));
}
