使用 Google 表格中某列中的電子郵件地址發送電子郵件

Question

我正在嘗試創建代碼，該代碼將使用谷歌表格中特定列的地址發送電子郵件。 我希望代碼在其他用戶編輯工作表后發送電子郵件。 例如，有人在工作表的一行中輸入請求 - 然后將電子郵件發送給請求的經理。 這是我到目前為止所擁有的...

function SendEmail(){
// Fetch the email address
var emailRange = SpreadsheetApp.getActiveSpreadsheet().getSheetByName("HLP REQUESTS").getRange("K:K");
var emailAddress = emailRange.getValues()[0][0];
// Send Alert Email.
var message = 'A request has been submitted for professional learning related to an HLP you champion.  Please check the Design Team Notes document in case follow-up is required.'; // Second column
var subject = 'HLP Request for Professional Learning';
MailApp.sendEmail(emailAddress, subject, message);
}

當我運行上面的代碼時，我收到一個錯誤 - 異常：發送電子郵件失敗：沒有收件人。 K列中有一個有效的電子郵件地址，所以我有點困惑。

如果您想從 K 列的最后一個單元格中獲取電子郵件地址，可以通過以下方式完成：

function SendEmail(){
  var emailRange = SpreadsheetApp.getActiveSpreadsheet()
    .getSheetByName("HLP REQUESTS").getRange("K:K");

  var emailAddress = emailRange.getValues()
    .flat()           // convert a 2d array into a flat array
    .filter(String)   // remove empty elements from the array
    .pop();           // get the last element from the array

  var message = 'A request has been submitted for professional learning related to an HLP you champion.  Please check the Design Team Notes document in case follow-up is required.';
  var subject = 'HLP Request for Professional Learning';

  MailApp.sendEmail(emailAddress, subject, message);
}

更新

這是帶有可安裝觸發器onEdit的完整實現，該觸發器在選中復選框（在 L 列中）后立即發送電子郵件：

// global variables
var SS = SpreadsheetApp.getActiveSpreadsheet(); // get the srpreadsheet
var checkbox_col = 12;                          // column with checkboxes (L in this case)

// the main function
function sendEmail(e) {
  try {
    var {rowStart, columnStart} = e.range;   // get row and column of the cell that was edited
    if (columnStart != checkbox_col) return; // do nothing if it was not column with checkboxes
    if (e.value != 'TRUE') return;           // do nothing if the checkboxs was unchecked
    e.range.setValue(false);                 // else uncheck the chekbox
        
    var sheet = SS.getSheetByName('HLP REQUESTS');                // get the sheet
    var emailAddress = sheet.getRange('K' + rowStart).getValue(); // get email addres from current row, column K

    var message = 'A request has been submitted for professional learning related to an HLP you champion. Please check the Design Team Notes document in case follow-up is required.';
    var subject = 'HLP Request for Professional Learning';

    MailApp.sendEmail(emailAddress, subject, message);       // send the message
    SS.toast('Email to ' + emailAddress + ' has been sent');
  } 
  catch(e) { SpreadsheetApp.getUi().alert(e) }
}


// additional functions -------------------------------------------------------------------------

// insatll the trigger
function install_onEidt_trigger() {
  ScriptApp.newTrigger('sendEmail').forSpreadsheet(SS).onEdit().create();
  SS.toast('Trigger was installed');
}

// remove all triggers
function remove_all_triggers() {
  ScriptApp.getProjectTriggers().forEach(t => ScriptApp.deleteTrigger(t));
  SS.toast('All triggers were remoded');
}

// custom menu to install and remove triggers
function onOpen() {
  SpreadsheetApp.getUi().createMenu('⚙️ Scripts')
  .addItem('Install trigger', 'install_onEidt_trigger')
  .addItem('Remove all triggers', 'remove_all_triggers')
  .addToUi();
}

為了使它工作，你有：

• 重新加載電子表格（或手動運行onEdit()函數）以獲取自定義菜單腳本
• 在自定義菜單中運行項目安裝觸發器
• 之后，只要用戶單擊 L 列中的復選框，它就會嘗試將消息從當前行的 K 列發送到地址

我的測試表如下所示：

發送電子郵件

function SendEmail() {
  const ss = SpreadsheetApp.getActive();
  const rsh = ss.getSheetByName("HLP REQUESTS");
  const emails = rsh.getRange("K1:K" + rsh.getLastRow()).getDisplayValues().flat();
  var message = 'A request has been submitted for professional learning related to an HLP you champion.  Please check the Design Team Notes document in case follow-up is required.';
  var subject = 'HLP Request for Professional Learning';
  emails.forEach(e => {
     MailApp.sendEmail(e, subject, message);
  });
}

如果您希望將此附加到 onEdit，您將不得不重新考慮該過程，因為 onEdit 觸發器會在對任何工作表的每次編輯時觸發，並且很可能您將需要使用可安裝的 onEdit，以便您可以執行需要權限的操作。 我建議您暫時使用 onEdit 簡單觸發器。 查看事件對象並以低開銷成本查看可用的內容。
