如何使用Apps脚本随机化多个问题选择？

function randomizeOptions() {
  var form = FormApp.getActiveForm();
  var items = form.getItems(FormApp.ItemType.MULTIPLE_CHOICE);
  
  for (var i = 0; i < items.length; i++) {
    var item = items[i];
    var choices = item.asMultipleChoiceItem().getChoices();
    
    // 随机化选项
    choices = shuffleArray(choices);
    
    // 更新问题选择的选项
    item.asMultipleChoiceItem().setChoices(choices);
  }
}

// 随机化数组
function shuffleArray(array) {
  for (var i = array.length - 1; i > 0; i--) {
    var j = Math.floor(Math.random() * (i + 1));
    var temp = array[i];
    array[i] = array[j];
    array[j] = temp;
  }
  return array;
}
