谷歌表单在信号提交时发送重复的电子邮件

Question

我想做一个谷歌表单向提交者发送电子邮件，我使用此代码指令使用应用脚本方法如下...表单（提交）>工作表（响应）>应用脚本>获取文档文件作为电子邮件模板 > 发送电子邮件

我的问题是提交应用程序会重复发送多封电子邮件。不管我做什么 这是脚本的应用程序是从这里获取的

  var EMAIL_TEMPLATE_DOC_URL = 'https://docs.google.com/document/d/1M2n7iOkl4IeKmuTjU95ibQN6W6UqYtkA9d99fccPd_Y/edit?usp=sharing';
  var EMAIL_SUBJECT = 'title';

  /**
   * Installs a trigger on the Spreadsheet for when a Form response is submitted.
   */
  function installTrigger() {
    ScriptApp.newTrigger('onFormSubmit')
        .forSpreadsheet(SpreadsheetApp.getActive())
        .onFormSubmit()
        .create();
  }

  /**
   * Sends a customized email for every response on a form.
   *
   * @param {Object} e - Form submit event
   */
  function onFormSubmit(e) {
    var responses = e.namedValues;

    // If the question title is a label, it can be accessed as an object field.
    // If it has spaces or other characters, it can be accessed as a dictionary.
    var timestamp = responses.Timestamp[0];
    var email = responses['Email Address'][0].trim();
    var name = responses.Name[0].trim();

    // If there is at least one topic selected, send an email to the recipient.
    var status = 'Email Sent';

    // Append the status on the spreadsheet to the responses' row.
    var sheet = SpreadsheetApp.getActiveSheet();
    var row = sheet.getActiveRange().getRow();
    var column = e.values.length + 1;

    sheet.getRange(row, column).setValue(status);

    MailApp.sendEmail({
      to: email,
      subject: EMAIL_SUBJECT,
      htmlBody: createEmailBody(name),
    });
    
    
    Logger.log('status=' + status + '; responses=' + JSON.stringify(responses));
  }

  /**
   * Creates email body and includes the links based on topic.
   *
   * @param {string} name - The recipient's name.
   * @param {string[]} topics - List of topics to include in the email body.
   * @return {string} - The email body as an HTML string.
   */
  function createEmailBody(name) {

    // Make sure to update the emailTemplateDocId at the top.
    var docId = DocumentApp.openByUrl(EMAIL_TEMPLATE_DOC_URL).getId();
    var emailBody = docToHtml(docId);
    emailBody = emailBody.replace(/{{NAME}}/g, name);
    return emailBody;
  }

  /**
   * Downloads a Google Doc as an HTML string.
   *
   * @param {string} docId - The ID of a Google Doc to fetch content from.
   * @return {string} The Google Doc rendered as an HTML string.
   */
  function docToHtml(docId) {
    // Downloads a Google Doc as an HTML string.
    var url = 'https://docs.google.com/feeds/download/documents/export/Export?id=' +
              docId + '&exportFormat=html';
    var param = {
      method: 'get',
      headers: {'Authorization': 'Bearer ' + ScriptApp.getOAuthToken()},
      muteHttpExceptions: true,
    };
    return UrlFetchApp.fetch(url, param).getContentText();
  }

我试图这样做。在发送电子邮件之前检查最后一列是否为空。发送后，Email Sent 将失败，我的事情是限制电子邮件重复。但没有。

if(sheet.getRange(row, column).getValue() == "")
{
    sheet.getRange(row, column).setValue(status);

    MailApp.sendEmail({
      to: email,
      subject: EMAIL_SUBJECT,
      htmlBody: createEmailBody(name),
    });
}

我试着统计一下它发送了多少封电子邮件。最后一个单元格显示 0，它发送了重复的电子邮件。

if(sheet.getRange(row, column).getValue() == "")
{
    sheet.getRange(row, column).setValue(0);
}
else
{
    sheet.getRange(row, column).setValue(sheet.getRange(row, column).getValue + 1);

    MailApp.sendEmail({
      to: email,
      subject: EMAIL_SUBJECT,
      htmlBody: createEmailBody(name),
    });
}

使用后...

 ScriptApp.getProjectTriggers().forEach(trigger => Logger.log(trigger.getHandlerFunction() + ' - ' + trigger.getEventType()))

这就是我得到的

Answer 1

正如 Cooper 在评论中提到的，您可能安装了多个触发器。

您可以检查项目的触发器页面以查看重复项，或运行此行。

ScriptApp.getProjectTriggers().forEach(trigger => Logger.log(trigger.getHandlerFunction() + ' - ' + trigger.getEventType()))

如果您有重复的触发器，上面的行将像这样记录：

只需删除重复的邮件，只保留其中的 1 个，这样您的邮件就不会再发送重复的邮件了。

删除触发器页面中的重复项后，只应保留 1 个触发器：
