在新的表單提交條目上發送重複的電子郵件

Question

我有以下腳本根據表單提交中的一個字段發送電子郵件給適當的人。它正在正常工作，但每次提交新條目時它都會發送多封電子郵件，我不知道爲什麼。有人能告訴我我的代碼中有什麼問題來解決這個問題嗎？

function sendEmails() { 
    var sheet = SpreadsheetApp.getActiveSheet(); 
    var startRow = 2; // First row of data to process 
    var numRows = 2; // Number of rows to process 
    // Fetch the range of cells A2:B3 
    var dataRange = sheet.getRange(startRow, 1, numRows, 3) 
    // Fetch values for each row in the Range. 
    var data = dataRange.getValues(); 
    var email1 = "A@A.com"; 
    var email2 = "B@B.com"; 
    for (i in data) { 
    var row = data[i]; 
    var emailAddress = row[0]; // First column 
    var message = row[1];  // Second column 
    var subject = "Sending emails from a Spreadsheet"; 
    if (message = "cat") { 
    MailApp.sendEmail(email1, subject, message); 
    if (message = "dog") { 
    MailApp.sendEmail(email2, subject, message); 
    } 
    } 
    } 
     } 

Answer 1

我敢肯定表單提交的最後一行結束，並通過行迭代是不必要的。這假定你沒有用數組公式和你的表單提交表格。

function sendEmails() { 
    var sheet = SpreadsheetApp.getActiveSheet(); 
    var row = sheet.getLastRow(); 
    var dataRange = sheet.getRange(row, 1, 1, sheet.getLastColumn()); 
    var data = dataRange.getValues()[0]; 

    var email1 = "A@A.com"; 
    var email2 = "B@B.com"; 

    var emailAddress = data[0]; // First column 
    var message = data[1];  // Second column 
    var subject = "Sending emails from a Spreadsheet"; 

    if (message == "cat") { 
    MailApp.sendEmail(email1, subject, message); 
    }; 
    if (message == "dog") { 
    MailApp.sendEmail(email2, subject, message); 
    }; 
    } 

最後一部分也許可以與桑迪的建議或開關>情況下

這些行：

if (message = "cat") { 
    MailApp.sendEmail(email1, subject, message); 
if (message = "dog") { 
    MailApp.sendEmail(email2, subject, message); 
} 

應該是：

var email;//Create a new variable 

if (message == "cat") { 
    email = email1; 
} else if (message == "dog") { 
    email = email2; 
} 

MailApp.sendEmail(email, subject, message);
