從Google電子表格發送自動電子郵件？

Question

僅當單擊運行按鈕時，此代碼才能工作。

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

function sendEmails2() {
  var sheet = SpreadsheetApp.getActiveSheet();
  var startRow = 2;  // First row of data to process
  var numRows = sheet.getLastRow()-1;   // Number of rows to process
  var dataRange = sheet.getRange(startRow, 2, numRows, sheet.getLastColumn());
  // 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[0];  // First column
    var message = row[1];       // Second column
    var emailSent = row[2];     // Third column
    if (emailSent != EMAIL_SENT) {  // Prevents sending duplicates
      var subject = "Sending emails from a Spreadsheet";
      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();
    }
  }
}

我希望如何在能夠發送新郵件時自動發送電子郵件，而無需單擊運行按鈕（如果可以的話）？

Answer 1

@cordova是正確的，只要有新消息，您就可以自動發送電子郵件，而無需單擊運行按鈕。

您可以使用腳本服務以編程方式觸發它。 調用ScriptApp.newTrigger（functionName）返回一個TriggerBuilder

下面的示例演示如何創建兩個時間驅動的觸發器，一個觸發器每6小時觸發一次，另一個觸發器每個星期一上午9點​​觸發（在腳本設置的時區中）。

function createTimeDrivenTriggers() {
  // Trigger every 6 hours.
  ScriptApp.newTrigger('myFunction')
      .timeBased()
      .everyHours(6)
      .create();

  // Trigger every Monday at 09:00.
  ScriptApp.newTrigger('myFunction')
      .timeBased()
      .onWeekDay(ScriptApp.WeekDay.MONDAY)
      .atHour(9)
      .create();
}
