 <div style="text-align: center;">
  <a href="#" onclick="handleMsg(msg)">點我有彈窗!</a>
  <a href="#" onclick="handleDomMsg(domMsg)">點我有彈窗!</a>
 </div>

 <span class="popupStyle" id="popupMsg">提示信息!</span>
 

 <script>
  const msg = "我是樣式彈窗";
  const domMsg = "我是DOM彈窗";

  // 樣式彈窗
  function handleMsg(message) {
   const popup = document.getElementById("popupMsg");
   popup.innerHTML = message || "Hello, World";
   popup.style.display="block";
   setTimeout(() => {
    popup.style.display="none"
   }, 1000);
  }

  // DOM 彈窗
  function handleDomMsg(message) {
   const div = document.createElement("div");
   document.body.appendChild(div);
   div.innerHTML = message || "this is a Message";
   div.className = "popupStyle";
   div.style.display = "block";

   setTimeout(() => {
    div.remove();
   }, 1000);
  }
 </script>
</body>
</html>
