如何将href URL插入Javascript变量？

Question

我正在尝试在Google Apps中创建用于自动回复的脚本，并希望该回复具有某种格式。由于引号随着href标签的打开而闭合，因此我一直在语法错误。有没有一种方法可以将URL插入html消息中？我的涂鸦在下面。

function autoReply() 
var interval = 5;    //  if the script runs every 5 minutes; change otherwise
  var message = "We are out of the office until Monday morning and will reply to your email then. If you are having an emergency, please text (800) 590-2508, we'll do our best to reply as soon as possible.";
  var htmlMessage = "<p>Hi,</p><p>Thanks for your message.</p><p>We are out of the office until Monday morning and will reply to your email then. In the meantime, check out some helpful resources:</p><p><a href="https://sampleurl.com" target="_blank" rel="noopener">Link text</a></p><p><a href="https://anothersammple.com" target="_blank" rel="noopener">Link text</a></p><p>If you are having an emergency, please text (800) 000-0000, we'll do our best to get back to you as soon as possible.</p><p>Have a pleasant weekend,</p><p>My Signature</p>";
  var date = new Date();
  var day = date.getDay();
  var hour = date.getHours();
  if ([6,0].indexOf(day) > -1) 
    var timeFrom = Math.floor(date.valueOf()/1000) - 60 * interval;
    var threads = GmailApp.search('is:inbox after:' + timeFrom);
    for (var i = 0; i < threads.length; i++) 
      if (threads[i].isUnread())
      threads[i].reply(message, htmlBody: htmlMessage);
      threads[i].markRead();
      threads[i].star();

错误在第4行上

 var htmlMessage = "<p>Hi,</p><p>Thanks for your message.</p><p>We are out of the office until Monday morning and will reply to your email then. In the meantime, check out some helpful resources:</p><p><a href="https://sampleurl.com" target="_blank" rel="noopener">Link text</a></p><p><a href="https://anothersammple.com" target="_blank" rel="noopener">Link text</a></p><p>If you are having an emergency, please text (800) 000-0000, we'll do our best to get back to you as soon as possible.</p><p>Have a pleasant weekend,</p><p>My Signature</p>";

htmlMessage =后的引号打开消息，而第一个href =后的引号将其关闭，因此消息的其余部分破坏了语法。

关于如何在var语句下包含整个html的任何见解？

谢谢！
