从Google Apps发送电子邮件

我对我的Google Apps自定义脚本感到困惑（特别是对于Google Spreadsheets） .

我从https://developers.google.com/apps-script/articles/sending_emails#section-2-improvements（请参阅"Section 2: Improvements"）重现了这一课，但它不起作用：即使单元格已经包含"EMAIL_SENT"（我使用"NOTIFICATION_SENT"而不是这个），脚本也会再次重新发送所有电子邮件 .

以下是自定义脚本的来源：

var NOTIFICATION_SENT = "NOTIFICATION_SENT";

function NotifyNewBooking() {
  var sheet = SpreadsheetApp.getActiveSheet();
  var startRow = 2;  // First row of data to process
  var numRows = 47;   // Number of rows to process
  // Fetch the range of cells A2:N48
  var dataRange = sheet.getRange(startRow, 1, numRows, 17)
  // Fetch values for each row in the Range.
  var data = dataRange.getValues();
  for (var i = 0; i < data.length; ++i) {
    var row = data[i];
    var emailAddress = "natalya@berdyanskaya56.ru";
    var subject = "Строка № " + row + ": " + "новое бронирование";
    var message = "Уведомление о новом бронировании!" + "\n" + "\nДанные нового бронирования:" + "\n" + "\nЗаезд: " + row[0] + "\nВыезд: " + row[1] + "\nНомер: " + "«" + row[2] + "»" + "\nТип размещения: " + row[3] + "\nЦена за ночь: " + row[4] + " руб." + "\nВнесённый депозит: " + row[8] + " руб." + "\n" + "\nИмя и фамилия гостя: " + row[5] + "\nМобильный телефон: " + row[6] + "\nЭлектронная почта: " + row[7] + "\n" + "\nПримечание: " + row[11] + "\n" + "\n* Просмотреть список всех бронирований можно тут: " + "www.bitly.com/b56guests";  
    var notificationSent = row[17];     // The column where notification status is put
    if (notificationSent != NOTIFICATION_SENT) {  // Prevents sending duplicates
      MailApp.sendEmail(emailAddress, subject, message, {name: "Мини-гостиница Бердянская 56", replyTo: "ruslan@berdyanskaya56.ru"});
      sheet.getRange(startRow + i, 17).setValue(NOTIFICATION_SENT);
      // Make sure the cell is updated right away in case the script is interrupted
      SpreadsheetApp.flush();
    }
  }
}

此处的目标是仅在列 row[17] 中的单元格不包含 NOTIFICATION_SENT 时发送电子邮件 . 请给我一些强有力的建议如何解决它 .

非常感谢你提前！

    问题出在这一行： var notificationSent = row[17];

    尝试通过记录值 Logger.log(row[17]) 和 Logger.log(row[16]) 来调试代码，您将在行[17]中获得 undefined 并在行[16]中获得 NOTIFICATION_SENT .

    Why? 因为范围 . getValues返回一个二维数组，数组索引从0开始 .

    它也在documentation中指定 .

    请记住，当范围索引从1,1开始时，JavaScript数组将从[0] [0]索引 .

    因此，虽然行很好，因为你已经在for循环中将i初始化为0 .

    for (var i = 0; i < data.length; ++i) { 
    var row = data[i]; 
    ....

    获取列时，应从索引中减去1 .

    var notificationSent = row[17 - 1];

    因为如果你有17列，那么数组中的第一个值将从索引0开始到16 .
