如何根据选择的选项显示两个链接？

<select id="optionSelect">
  <option value="link1">选项1</option>
  <option value="link2">选项2</option>
  <option value="link3">选项3</option>
</select>

document.getElementById('optionSelect').addEventListener('change', function() {
  var selectedOption = this.value;
  var link1 = "https://www.example.com/link1";
  var link2 = "https://www.example.com/link2";
  
  if (selectedOption === "link1") {
    document.getElementById('linkContainer').innerHTML = "<a href='" + link1 + "'>链接1</a>";
  } else if (selectedOption === "link2") {
    document.getElementById('linkContainer').innerHTML = "<a href='" + link2 + "'>链接2</a>";
  } else {
    document.getElementById('linkContainer').innerHTML = "";
  }
});

<div id="linkContainer"></div>
