google-apps-script - 表单谷歌脚本防止重复

Question

我正在制作一个谷歌表单，我有一个名为 name 的字段，其中包含标题、公司和电子邮件地址等其他字段。如果数据库中已经有一个特定的人，我希望其他信息用新信息替换旧信息（即更新功能），但是我在使用 Google Apps 脚本时遇到了麻烦，因为我找到了文档比较可怜。有人介意帮我一把吗？

这不会阻止谷歌表单首先提交重复值，但我认为你想要的看起来像......

function updateExisting() {
  var ss = SpreadsheetApp.getActiveSpreadsheet(),
      s = ss.getSheetByName('Sheet1'),
      lastRow = s.getLastRow(),
      lastValues = s.getRange('A'+lastRow+':E'+lastRow).getValues(),
      name = lastValues[0][0],
      allNames = s.getRange('A2:A').getValues(), 
      row, len;

  // TRY AND FIND EXISTING NAME
  for (row = 0, len = allNames.length; row < len - 1; row++)
    if (allNames[row][0] == name) {
      // OVERWRITE OLD DATA
      s.getRange('A2').offset(0, 0, row, lastValues.length).setValues([lastValues]);
      // DELETE THE LAST ROW
      s.deleteRow(lastRow);
      break;}
}

这必须由工作表内的表单提交触发器触发。

文档可能是压倒性的。他们通常只做 1 或 2 行示例，尽管如果您浏览所有教程，则会有更多完成的示例。开发人员更多地需要制作这些类型的脚本。

这是我解决它的方法...

我使用他们的电子邮件地址来检查重复项，但你可以使用任何你想要的东西：

function SendConfirmationMail(e) {
    
        // Fetch data from latest submission on spreadsheet
        var ss = SpreadsheetApp.getActiveSheet();
                   
        // Access the workbook
        var wrkBk = SpreadsheetApp.getActiveSpreadsheet();
        
        // Fetch the necessary sheets
        var ssResponses = wrkBk.getSheetByName("Form Responses");
        var ssAutomailer = wrkBk.getSheetByName("Automailer"); // <---this sheet is in another tab that has the email's subject and body so this script can be dynamically updated.
      
        // Fetch & store data from form submissions
        var numRows = ssResponses.getLastRow();  // <--- store # of total rows
        var lastfNameCell = "B" + numRows;  // <--- store the range of last cell containing fName data
        var lastEmailCell = "C" + numRows;  // <--- store the range of last cell containing email data
        var numPrevRows = numRows -1;  // <--- store the # of previous rows
        var lastPrevEmailCell = "C" + numPrevRows; // <--- store the range of last "previous" cell that contains email data in A1 notation
        var lastPrevEmailRange = "C2:" + lastPrevEmailCell; // <--- store range of ALL previous cells containing email data in A1 notation
        var fName = ssResponses.getRange(lastfNameCell).getValue();  // <--- store the fName from latest submission 
        var email = ssResponses.getRange(lastEmailCell).getValue();  // <--- store the email address from latest submission
        var prevEmails = ssResponses.getRange(lastPrevEmailRange).getValues(); // <--- store range of all previous email addresses into an array  
      
        // Convert email list to string for search functionality
        prevEmails = prevEmails.toString();
      
        // Run an index search to see if the email address already exists
        // If no match is found, -1 will be the result and we can continue on...
        if (prevEmails.indexOf(email) == "-1") {
      
            // Fetch own email address for cc functionality
            var cc = Session.getActiveUser().getEmail();
        
            // Set sender's name
            var sendername = "Your Site/Business Name Goes Here"
          
            // Store data from Automailer cells
            var subject = ssAutomailer.getRange('A3').getValue();
            var body = ssAutomailer.getRange('B3').getValue();
      
            // Store HTML template and it's contents
            var htmlFile = HtmlService.createTemplateFromFile("new-subscriber-template.html");
            var htmlContent = htmlFile.evaluate().getContent();
      
            // Convert spreadsheet body content to HTML
            var htmlBody = body.replace(/\n/g, '<br>'); //<----- converts newlines to HTML format

            // Replace placeholder data in htmlContent
            htmlContent = htmlContent.replace("[fName]", fName);
            htmlContent = htmlContent.replace("[body]", htmlBody);
    
            // Add a personalized greeting to plain text body and store to new variable
            var textbody = "Hi " + fName + ",\n\n" + body;
                
            // Send the email!
            GmailApp.sendEmail(email, subject, textbody,                           
            // Extra email paramaters: un-comment the first section of this line to send yourself a carbon copy.
            {/*cc: cc, */name: sendername, htmlBody: htmlContent});
                                               
        }
        // If the index search found a duplicate, do this instead
        else { 
                        
            // Send error notification email
            GmailApp.sendEmail(email, "There was an error with your request...", "Looks like you're already a subscriber!",                          
            // Extra email paramaters: un-comment the first section of this line to send yourself a carbon copy.
            {/*cc: cc, */name: sendername, htmlBody: "Looks like you're already a subscriber!" });
          
            // Be gone duplicate!
            ssResponses.deleteRow(numRows);
        } 
 
}

请记住，如果您搜索的内容几乎不是电子邮件，您可能需要使用一些额外的搜索参数来排除误报。我打算使用以下内容，但我认为电子邮件足够独特，以避免在代码中出现这一额外行：

var emailSearch = ',' + email + ',' <--- commas on either end added to match the entire cell on the index search
