如何更新indexedDB中的条目而不创建新条目

const request = indexedDB.open('myDatabase', 1);

request.onsuccess = function(event) {
  const db = event.target.result;
  const objectStore = db.createObjectStore('myObjectStore', { keyPath: 'id' });
};

const transaction = db.transaction(['myObjectStore'], 'readwrite');
const objectStore = transaction.objectStore('myObjectStore');

const request = objectStore.get('key');
request.onsuccess = function(event) {
  const data = event.target.result;
  // 对数据进行更新操作
};

data.property = 'new value';

const updateRequest = objectStore.put(data);
updateRequest.onsuccess = function(event) {
  console.log('条目更新成功');
};
