我认为一种解决方案是创建一个包含列标题的电子表格：事件 ID、事件名称、描述、开始时间、结束时间、位置、来宾列表，然后将此脚本添加到电子表格中。 calendarImport() 将导入所有日历事件并将它们写入工作表。然后，您可以修改电子表格行中的事件（将位置更改为月球），并运行 calendarCreateEvent 根据您所做的更改创建一个新事件。它将自动向所有旧与会者发送通知以接受新活动，因为这是一个新邀请。
我非常接近该解决方案，但现在我在访问日历以创建新事件时遇到了问题。我认为这是因为我从 onEdit 事件函数中调用它。已经很晚了，但是如果您重写脚本的第三部分以获取事件数据范围，然后使用 for/if 循环来检查添加日期与修改日期，那么您应该能够创建一个新事件，并删除旧的事件。这会将事件详细信息更改的通知推送给已经接受旧事件的每个人。
我认为，鉴于您一开始提供的代码示例，您可能已经知道如何做到这一点，但如果您不知道，我可能会在明天晚上拼凑一些东西来搜索已重新创建的旧事件并删除它们。
Here's my spreadsheet and code in action.
function calendarImport(){
//http://www.google.com/google-d-s/scripts/class_calendar.html#getEvents
// The code below will retrieve events between 2 dates for the user's default calendar and
// display the events the current spreadsheet

var calId = cal.getId();
var sheet = SpreadsheetApp.getActiveSheet();
var sheetName = SpreadsheetApp.getActiveSheet().setName(calId +" Calendar Data");
var events = cal.getEvents(new Date("March 9, 2014"), new Date("March 14, 2014"));
for (var i=0;i<events.length;i++) {
