如何使用下拉列表选项删除数组的HTML (Javascript)

<select id="mySelect"></select>
<button onclick="deleteElement()">删除选项</button>

var myArray = ["选项1", "选项2", "选项3", "选项4"];
var select = document.getElementById("mySelect");

for (var i = 0; i < myArray.length; i++) {
  var option = document.createElement("option");
  option.text = myArray[i];
  select.add(option);
}

function deleteElement() {
  var selectedIndex = select.selectedIndex; // 获取选择的索引
  myArray.splice(selectedIndex, 1); // 从数组中删除选中的元素
  select.options[selectedIndex].remove(); // 从下拉列表中删除选中的选项
}
