同步Google表格和Google日历。双向同步

Question

我希望能够将在Google日历中创建的新事件发送到Google表格，并将在Google表格中创建的新事件（行）发送到Google日历。

不想在Google日历或Google表格中创建重复的事件。

我有单独的程序可以在两个单独的Google表格中完成这些任务。两种功能均可独立工作，但我想将它们合并并使用一个Google表格工作。使用下面的代码，将删除我的工作表标题，并且无限次数地重新创建同一事件。 日历ID在单元格J2中。

Google表格标题如下：

|事件日期|事件标题|开始时间|结束时间|位置|事件ID

function getEvents()
{
var sheet = SpreadsheetApp.getActiveSheet()
var headerRows = 1; 
var range = sheet.getDataRange(); 
var data = range.getValues()
var calId = sheet.getRange("J2").getValue(); 
var cal = CalendarApp.getCalendarById(calId);
var events = cal.getEvents(new Date("9/1/2019 12:00 AM"), new Date("1/1/2090 11:59 PM"));

for(var i=0; i<events.length; i++){
var date = events[i].getStartTime();
var title = events[i].getTitle();
var tstart = events[i].getStartTime();
var tstop = events[i].getEndTime();
var loc = events[i].getLocation();
var id = events[i].getId();

for (var j=0; i<data.length; j++) { 
if (j < headerRows) continue;
var row = data[j];
sheet.getRange(j, 2).setValue(title);
sheet.getRange(j, 3).setValue(tstart);
sheet.getRange(j, 4).setValue(tstop);
sheet.getRange(j, 5).setValue(loc);
sheet.getRange(j, 6).setValue(id);
}
}
} 

function exportEvents() { 
var sheet = SpreadsheetApp.getActiveSheet();
var headerRows = 1;  // Number of rows of header info (to skip) 
var range = sheet.getDataRange(); 
var data = range.getValues(); 
var calId = sheet.getRange("J2").getValue(); 
var cal = CalendarApp.getCalendarById(calId); 

for (i=0; i<data.length; i++) { 
if (i < headerRows) continue; // Skip header row(s) 
var row = data[i]; 
var date = new Date(row[1]);  // First column 
var title = row[2];           // Second column 
var tstart = new Date(row[3]); 
tstart.setDate(date.getDate()); 
tstart.setMonth(date.getMonth()); 
tstart.setYear(date.getYear()); 
var tstop = new Date(row[4]); 
tstop.setDate(date.getDate()); 
tstop.setMonth(date.getMonth()); 
tstop.setYear(date.getYear()); 
var loc = row[5]; 
var id = row[6];              // Sixth column == eventId 

// Check if event already exists, update it if it does 

try { 
  var event = cal.getEventSeriesById(id); 
} 

catch (e) { 
  // do nothing - we just want to avoid the exception when event doesn't exist 
} 

if (!event) { 
  //cal.createEvent(title, new Date("March 3, 2010 08:00:00"), new Date("March 3, 2010 09:00:00"), {description:desc,location:loc}); 
  var newEvent = cal.createEvent(title, tstart, tstop, {location:loc}).getId(); 
  row[6] = newEvent;  // Update the data array with event ID 
} 

else { 
  event.setTitle(title); 
  event.setLocation(loc); 
  // event.setTime(tstart, tstop); // cannot setTime on eventSeries. 
  // ... but we CAN set recurrence! 
  var recurrence = CalendarApp.newRecurrence().addDailyRule().times(1); 
  event.setRecurrence(recurrence, tstart, tstop); 
} 
debugger; 
} 
 // Record all event IDs to spreadsheet 

 range.setValues(data); 
} 

代码应在创建的每个事件中（在Google表格或Google日历中）在Google表格中输出1行和1个Google日历约会。
