在对象33463中找不到函数getMonth

Question

我创建了一个脚本，通过Birthday Reminder向特定人发送电子邮件。这个用到前天工作。我不知道为什么我会收到无法找到函数getMonth的错误，任何人都可以告诉错误在哪里

function emailAlert() {

  // Short circuit if email notice is set to "No". This causes an error and the script stops.
  if (turnOnEmailNotice.toLowerCase() == "no")
  { 
    Logger.log("The Email Notification is NOT turned ON. System will Exit.");
    exit 
  } 

  //Get the total number of filled row in the sheet.
  var currentRowAT = 2;
  var currentCellValueAT = "start";
  while (currentCellValueAT != ""){
    if (currentCellValueAT = birthdaysSheet.getRange("G" + currentRowAT).getValue() != ""){
    currentRowAT = currentRowAT +1;
    }
  }
  var birthdaysSheetLastRow = currentRowAT - 1;

  // Get today's Date (with Month, Date and Year)
  var today = new Date();
  var todayMth = today.getMonth()+1;
  var todayDate = today.getDate();
  var todayYear = today.getFullYear();


  // Check sheet cell for match to alertDate, k is the current row number being checked. Starting at 2 as the row #1 is for the headers
  for (k=2; k < birthdaysSheetLastRow + 1; k++)
  {
     var targetBday = new Date();
     targetBday = birthdaysSheet.getRange("P" + k).getValue();

     // If Birthday is not speicified, continue with the next row
     if (targetBday == ""){continue};

     var unadjTargetBday = new Date();
     var unadjTargetBdayMth = targetBday.getMonth()+1;
     var unadjTargetBdayDate = targetBday.getDate();
     var unadjTargetBdayYear = targetBday.getFullYear();
     var unadjTargetBday = targetBday;


     targetBday.setDate(targetBday.getDate()-daysInAdvance); // Calculating how many days in advance you want to trigger the notification. This is set in Settings Tab.
     var targetBdayMth = targetBday.getMonth()+1;
     var targetBdayDate = targetBday.getDate();

     if (targetBdayMth + " " + targetBdayDate == todayMth + " " + todayDate)
     {
       var targetBirthDateYearsOld = (today.getYear() - unadjTargetBday.getYear())-1900;
       prepareAndSendEmail(k, targetBirthDateYearsOld);       
     }
   } 
}

Answer 1

getValue将返回类型字符串/日期/数字，具体取决于电子表格中的单元格类型（请参阅菜单格式 - ＆gt;数字）。可以肯定的是，只需始终转换为日期类型。这是转换它的正确方法：

var targetBday = new Date(birthdaysSheet.getRange("P" + k).getValue());

简短回答

检查单元格值是Google表格的有效日期。

解释

来自https://developers.google.com/apps-script/reference/spreadsheet/range#getvalue（强调我的）

  

的getValue（）

     

返回范围中左上角单元格的值。价值可能是   类型为Number，Boolean，Date或String ，具体取决于   细胞即可。空单元格将返回一个空字符串。

为避免此类问题，您可以包含某种数据验证。您可以使用内置功能，例如条件格式，数据验证或类似编辑脚本以及try / catch或emailAlert脚本中的冗余验证。
