用什么方法可以替代sessionStorage来存储临时数据？

// 存储数据
localStorage.setItem('key', 'value');

// 获取数据
var data = localStorage.getItem('key');

// 存储数据
document.cookie = 'key=value';

// 获取数据
var cookieValue = document.cookie;

// 打开数据库
var request = indexedDB.open('database', 1);

// 创建对象仓库
request.onupgradeneeded = function(event) {
  var db = event.target.result;
  var objectStore = db.createObjectStore('store', { keyPath: 'id' });
};

// 存储数据
request.onsuccess = function(event) {
  var db = event.target.result;
  var transaction = db.transaction(['store'], 'readwrite');
  var objectStore = transaction.objectStore('store');
  var data = { id: 1, value: 'data' };
  var request = objectStore.add(data);
};

// 获取数据
request.onsuccess = function(event) {
  var db = event.target.result;
  var transaction = db.transaction(['store'], 'readonly');
  var objectStore = transaction.objectStore('store');
  var request = objectStore.get(1);
  request.onsuccess = function(event) {
    var data = event.target.result;
  };
};
