单击按钮后，列表中选中的复选框应该会消失

<ul id="checkboxList">
  <li><input type="checkbox" value="1">选项1</li>
  <li><input type="checkbox" value="2">选项2</li>
  <li><input type="checkbox" value="3">选项3</li>
</ul>
<button id="removeButton">移除选中的复选框</button>

var removeButton = document.getElementById("removeButton");
removeButton.addEventListener("click", function() {
  var checkboxList = document.getElementById("checkboxList");
  var checkboxes = checkboxList.getElementsByTagName("input");
  
  for (var i = checkboxes.length - 1; i >= 0; i--) {
    if (checkboxes[i].checked) {
      checkboxList.removeChild(checkboxes[i].parentNode);
    }
  }
});
