如何在颤动中获取单选按钮值

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

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

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

var option1 = document.getElementById("option1");
var option2 = document.getElementById("option2");
var option3 = document.getElementById("option3");

if (option1.checked) {
  console.log(option1.value); // 输出选中的值
} else if (option2.checked) {
  console.log(option2.value);
} else if (option3.checked) {
  console.log(option3.value);
}
