我正在尝试在运行响应命令时防止在Google工作表中出现重复的电子邮件响应

Question

我从Google表格教程中获得了此代码，并且可以正常工作，我想在我的同伴填写Google表单后发送电子邮件回复。该电子邮件可以正常工作，因此第一步已完成，但是即使我指定它不会发送重复的电子邮件，它仍将继续发送电子邮件。我的工作表如下：

    Time Stamp/Email Address/Message/Complete for columns A-D
    date-time/[email protected]/   Test1/  EMAIL_SENT
    date-time/ [email protected]/  Test2/  EMAIL_SENT
    date-time/[email protected]/   Test3/  EMAIL_SENT

    // This constant is written in column C for rows for which an email
    // has been sent successfully.
    var EMAIL_SENT = 'EMAIL_SENT';

    /**
     * Sends non-duplicate emails with data from the current spreadsheet.
     */
    function sendEmails2() {
      var sheet = SpreadsheetApp.getActiveSheet();
      var startRow = 2; // First row of data to process
      var numRows = 3; // Number of rows to process
      // Fetch the range of cells B1:D3
      var dataRange = sheet.getRange(startRow, 1, numRows, 3);
      // 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 = row[1]; // Second column
        var message = row[2]; // Third column
        var emailSent = row[3]; // Fourth column
        if (emailSent !== EMAIL_SENT) { // Prevents sending duplicates
          var subject = 'Your PFB Request';
          MailApp.sendEmail(emailAddress, subject, message);
          sheet.getRange(startRow + i, 4).setValue(EMAIL_SENT);
          // Make sure the cell is updated right away in case the script is interrupted
          SpreadsheetApp.flush();
        }
      }
    }

Answer 1

var dataRange = sheet.getRange(startRow, 1, numRows, 3);

getRange不是基于零的方法。您的定义定义的范围只有3列宽。它不包含“完成”列。

将其更改为：var dataRange = sheet.getRange(startRow, 1, numRows, 4);

“完整”列将等于行[3]（从零开始）。当前，row [3]没有值，可能是“ undefined”，它将解释为什么“ IF”语句不起作用。
