当选中状态具有某些逻辑时，无法选择单选按钮

<input type="checkbox" id="condition">满足某些条件
<br>
<label for="option1"><input type="radio" name="options" id="option1" value="option1">选项1</label>
<br>
<label for="option2"><input type="radio" name="options" id="option2" value="option2">选项2</label>

var condition = document.getElementById('condition');
var option1 = document.getElementById('option1');
var option2 = document.getElementById('option2');

condition.addEventListener('change', function() {
  if (condition.checked) {
    option1.disabled = true;
    option2.disabled = true;
  } else {
    option1.disabled = false;
    option2.disabled = false;
  }
});
