当单元格不为空时运行脚本

Question

当单元格（例如A1）不再为空时，脚本会发送自动邮件，并且需要被触发。

function sendEmails() {
  var sheet = SpreadsheetApp.getActiveSheet();
  var startRow = 2; 
  var numRows = 1; 

  var dataRange = sheet.getRange(startRow, 1, numRows, 11);

  var data = dataRange.getValues();
  for (i in data) {
    var row = data[i];
    var emailAddress = row[9]; 
    var message = row[10];
    var subject = 'Subject';
    MailApp.sendEmail(emailAddress, subject, message);
  }
}

Answer 1

您需要的只是一个简单的if语句：

function sendEmails() {
  var sheet = SpreadsheetApp.getActiveSheet();
  var startRow = 2; 
  var numRows = 1; 

  var dataRange = sheet.getRange(startRow, 1, numRows, 11);

  var data = dataRange.getValues();
  for (var i in data) {
    if (data[i][0] != '') { //check cell A is empty in the row the script is running for.
      var row = data[i];
      var emailAddress = row[9]; 
      var message = row[10];
      var subject = 'Subject';
      MailApp.sendEmail(emailAddress, subject, message);
    }
  }
}
