如何使下拉列表跟随所选内容中的链接？

<select id="mySelect" onchange="updateLink()">
  <option value="">请选择</option>
  <option value="https://www.example1.com">链接1</option>
  <option value="https://www.example2.com">链接2</option>
  <option value="https://www.example3.com">链接3</option>
</select>

<div id="linkContainer">
  <!-- 链接将在这里显示 -->
</div>

function updateLink() {
  var selectElement = document.getElementById("mySelect");
  var linkContainer = document.getElementById("linkContainer");
  var selectedValue = selectElement.value;

  if (selectedValue) {
    var link = document.createElement("a");
    link.href = selectedValue;
    link.textContent = "点击此处访问链接";
    linkContainer.innerHTML = "";
    linkContainer.appendChild(link);
  } else {
    linkContainer.innerHTML = "";
  }
}

#linkContainer {
  margin-top: 10px;
}
