如何获取单选按钮的不同id值

<input type="radio" id="option1" name="options" value="1">
<label for="option1">Option 1</label>

<input type="radio" id="option2" name="options" value="2">
<label for="option2">Option 2</label>

<input type="radio" id="option3" name="options" value="3">
<label for="option3">Option 3</label>

var radios = document.getElementsByName('options');
var selectedId;

for (var i = 0; i < radios.length; i++) {
  if (radios[i].checked) {
    selectedId = radios[i].id;
    break;
  }
}

console.log("Selected ID: " + selectedId);
