在电子邮件发送的表单中加入隐藏变量 - Google Apps脚本

Question

我有一些脚本通过电子邮件发送HTML表单，如下所示：

function sendFormEmail() {
    var ss = SpreadsheetApp.getActiveSpreadsheet();
    var sheet = ss.getSheetByName("Email list");
    var emailRange = sheet.getRange("B2:B");
    var emails = emailRange.getValues();
    var lastRow = emails.filter(String).length;
    var originalEmailRange = sheet.getRange("A2:A");

    // Logged emails

    var logSheet = ss.getSheetByName("Email log");
    var timeStampRange = logSheet.getRange("A2:A");
    var timeStamps = timeStampRange.getValues();
    var logEmailRange = logSheet.getRange("B2:B");
    var logEmails = logEmailRange.getValues();
    var lastLog = logEmails.filter(String).length;
    var adjustedLastLog = lastLog+2;
    var userRange = logSheet.getRange("C2:C");
    // Logger.log(adjustedLastLog);


    for(var i=0; i<lastRow; i++) {
    var toEmailAddress = emails[i];
    var htmlMessage = HtmlService.createHtmlOutputFromFile("form.html").getContent();
    var subject = "Connect";
    var message = "";
    logSheet.getRange("B"+(i+adjustedLastLog)).setValue(emails[i]);
    logSheet.getRange("A"+(i+adjustedLastLog)).setValue(new Date());
    logSheet.getRange("C"+(i+adjustedLastLog)).setValue(Session.getActiveUser().getEmail());
    MailApp.sendEmail(toEmailAddress, subject, message, {
      htmlBody: htmlMessage
    });  


    }
    originalEmailRange.setValue("");

    var ui = SpreadsheetApp.getUi();
      var result = ui.alert(
     'Good news!',
     "Your form was successfully sent to your database of emails. Go to the 'Email log' tab to see a log of all emails sent using this function.",
      ui.ButtonSet.OK);

}

我想要做的是以某种方式将活动用户的电子邮件地址解析为表单中的隐藏输入，以便当收到表单的用户提交该电子邮件地址时，将随之返回此电子邮件。

HTML表单中的输入是非常基本的文本输入，例如：

<input type="text"  style="border-radius: 10px; padding: 10px; width: 80%; border: 2px solid #1CA1F2" name="entry.2082149504" value="" class="ss-q-short" id="entry_2082149504" dir="auto" aria-label="And what is this person&#39;s email address?  " title="" style="">

我的理解是我可能需要使用Scriptlets，但我不理解语法，并试图玩它无济于事。有人能帮忙吗？

非常感谢

在{email}中放置像form.html这样的占位符：

<input type="hidden" name="email" value="{email}">

然后在发送之前将其替换为实际的电子邮件：

var htmlMessage = HtmlService.createHtmlOutputFromFile("form.html").getContent();
htmlMessage = htmlMessage.replace('{email}', toEmailAddress);
