Google 脚本 - Gmail.App，带有 if 语句的电子邮件正文

Question

我正在尝试根据某些条件从 Google 电子表格创建旅游确认电子邮件。

我创建了一个变量，如果语句和 ID 未显示在电子邮件中，我将添加该变量。

var mailContent = 
'Hello '+customerName +', thank you for the booking.<br><br>'+ "You have booked: "+tourName +" - "+tourType 
+ "<br><br><b>Tour Details:</b> " 
+"<br>Travel Date: "+tourDate
 if (tourLang !== "--------"){
       +"<br>Language: "+tourLang 
  }
+"<br>Pickup adress: "+tourPickup
 if (tourTime !== ""){
    +"<br>Pickup Time: "+tourTime
 }
+"<br>Number of Participants: "+tourPax

    +"<br><br> <b>Contact Details:  </b>"
    +"<br> Main customer: "+customerName
    +"<br> Phone: "+customerPhone
    if (customerOtherNames !== ""){
    +"<br> Names of all Participants: "+customerOtherNames
    }  
GmailApp.sendEmail(
customerEmail,
'Booking Confirmation '+voucherRealNumber,
mailContent,
{
  htmlBody: mailContent,     
  attachments: [createPDF],
  bcc: "test@test.com"
});

电子邮件看起来像这样：

“您好XYZ，感谢您的预订。您已经预订：Some - Tour 旅游详情：旅行日期：2021 年 12 月 24 日星期五

它在第一个 if 语句处停止。在这个特定的例子中，if 语句 == true，所以它应该添加它的内容以便继续脚本。

Answer 1

您需要指定在 if 语句中追加时使用的变量。您没有指定要附加字符串的变量，这就是它没有显示预期输出的原因。请参阅下面的示例脚本：

脚本：

  customerName = 'XYZ';
  tourName = 'Some';
  tourType = 'Tour';
  tourDate = 'Fri Dec 24 2021';
  tourLang = 'lang';
  tourTime = 'time';
  customerOtherNames = 'other names';
  tourPickup = 'pickup';
  tourPax = 'pax';
  customerPhone = 'phone';

  var mailContent =
    'Hello ' + customerName + ', thank you for the booking.<br><br>' + "You have booked: " + tourName + " - " + tourType
    + "<br><br><b>Tour Details:</b> "
    + "<br>Travel Date: " + tourDate

  if (tourLang !== "--------") {
    mailContent += "<br>Language: " + tourLang
  }
  
  mailContent += "<br>Pickup adress: " + tourPickup

  if (tourTime !== "") {
    mailContent += "<br>Pickup Time: " + tourTime
  }

  mailContent += "<br>Number of Participants: " + tourPax
    + "<br><br> <b>Contact Details:  </b>"
    + "<br> Main customer: " + customerName
    + "<br> Phone: " + customerPhone

  if (customerOtherNames !== "") {
    mailContent += "<br> Names of all Participants: " + customerOtherNames
  }

  Logger.log(mailContent);
