如何在IndexedDB索引中更改对象的值？

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

// 创建对象存储空间
request.onupgradeneeded = function(event) {
  var db = event.target.result;
  var objectStore = db.createObjectStore('myObjectStore', { keyPath: 'id' });
};

// 打开事务并获取对象存储空间
request.onsuccess = function(event) {
  var db = event.target.result;
  var transaction = db.transaction('myObjectStore', 'readwrite');
  var objectStore = transaction.objectStore('myObjectStore');

  // 获取对象
  var getRequest = objectStore.get('object1');
  getRequest.onsuccess = function(event) {
    var object = event.target.result;

    // 修改对象的值
    object.value = 'new value';

    // 更新对象
    var putRequest = objectStore.put(object);
    putRequest.onsuccess = function(event) {
      console.log('Object updated successfully');
    };
  };
};
