如何按列对ListView进行排序？

// 假设ListView的数据源是一个数组
var listViewData = [
  { name: 'John', age: 25, city: 'New York' },
  { name: 'Alice', age: 30, city: 'London' },
  { name: 'Bob', age: 20, city: 'Paris' }
];

// 定义排序函数，按照age列进行排序
function sortByAge() {
  listViewData.sort(function(a, b) {
    return a.age - b.age;
  });
  updateListView();
}

// 绑定排序函数到列头点击事件
var ageColumnHeader = document.getElementById('ageColumnHeader');
ageColumnHeader.addEventListener('click', sortByAge);

// 更新ListView的显示内容
function updateListView() {
  var listView = document.getElementById('listView');
  listView.innerHTML = '';
  for (var i = 0; i < listViewData.length; i++) {
    var item = document.createElement('div');
    item.innerHTML = listViewData[i].name + ', ' + listViewData[i].age + ', ' + listViewData[i].city;
    listView.appendChild(item);
  }
}
