用于根据列中的值发送电子邮件的脚本-脚本问题

Question

GAS的新手。我有一个Google Form可以输入电子表格。在观看了教程视频并阅读了其他帖子之后，我尝试创建一个脚本，该脚本将向第二列中的地址发送电子邮件，并根据另一列中的是或否发送另一封电子邮件（第25列）。它还包括另一列（26），我希望将发送电子邮件的日期填入其中，以确保每次运行此脚本时都不会发送重复的邮件。我已调试，但没有出现任何错误，但无法正常工作-我尚未收到电子邮件。帮助将不胜感激！这是一个示例电子表格：https://docs.google.com/spreadsheets/d/1AKaSOk1ZbnfKeadgB_mugnqplKzJJ3bDQ_KsRY0sMvQ/edit?usp=sharing

function sendEmail() {
  var ss = SpreadsheetApp.getActiveSpreadsheet();
  var responses = ss.getSheetByName("Field Trip Requests");

  var data = responses.getRange(2,1,responses.getLastRow()-1,25).getValues();

  data.forEach(function(row,i) {
    // variables
    var recipient = row[1];
    var destination = row[6];
    var approval = row[24];
    var emailSent = row[25];

    if(emailSent == ' ') {

      if(approval == "Y") {
        var body = "Your field trip request for " + 
          destination + 
            " has been approved! If you requested transportation, Najma will make arrangements and contact you if she requires more information." + 
              "<br><br>" + 
                "Cheers," + 
                  "<br><br>" + 
                    "Boaty McBoatface";

      }
      else if(approval == "N") {
        var body = "Your field trip request for " +
          destination +
            " has not been approved.  Please come and see me and we can chat!" +
              "<br><br>" +
                "Cheers," +
                  "<br><br>" +
                    "Boaty McBoatface";

      }

      var subject = "Your Field Trip Request";

      MailApp.sendEmail(recipient, subject, body)

      var d = new Date();

      responses.getRange(i + 1, 25).setValue(d);

    }

  })

}

Answer 1

如果此var data = responses.getRange(2,1,responses.getLastRow()-1,25).getValues();是正确的，则不存在行[25]，如下所示：

data.forEach(function(row,i) {
    // variables
    var recipient = row[1];
    var destination = row[6];
    var approval = row[24];
    var emailSent = row[25];

行从零开始到24结束

行是一个数组

也许这就是您想要的：

function sendEmail() {
  var ss=SpreadsheetApp.getActive();
  var sh=ss.getSheetByName("Field Trip Requests");
  var data=sh.getRange(2,1,responses.getLastRow()-1,25).getValues();
  data.forEach(function(row,i) {
    var recipient=row[0];
    var destination=row[5];
    var approval=row[23];
    var emailSent=row[24];
    if(emailSent=='' &&  approval=='Y') {
      var body=Utilities.formatString('Your field trip request for %s has been approved! If you requested transportation, Najma will make arrangements and contact you if she requires more information. <br><br>Cheers<br><br>Boaty McBoatface',destination);
    }else if(emailSent=='' && approval == "N") {
      var body=Utilities.formatString('Your field trip request for %shas not been approved.  Please come and see me and we can chat!<br><br>Cheers,<br><br>Boaty McBoatface',destination);     
    }
    var subject="Your Field Trip Request";
    MailApp.sendEmail(recipient, subject, body);
    sh.getRange(i+1,25).setValue(Utilities.formatDate(new Date, Session.getScriptTimeZone(), "MM/dd/yyyy"));
  })  
}

Answer 2

脚本的一个问题是，当它应该使用基于0的索引时，您正在使用基于1的索引

var recipient = row[1];
var destination = row[6];
var approval = row[24];
var emailSent = row[25];

上面是因为JavaScript对数组元素（以及其他东西）使用基于0的索引，所以代替了上面的用法

var recipient = row[0];
var destination = row[5];
var approval = row[23];
var emailSent = row[24];

另一个问题是以下情况：

emailSent == ' ' /* is emailSent equal to a blank space? */

应该是

emailSent == '' /* is emailSent equal to an empty string? */

以上是因为getValues()为空单元格返回一个空字符串
