如何在chrome扩展中使用IndexedDB？

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

request.onupgradeneeded = function(event) {
  let db = event.target.result;
  let objectStore = db.createObjectStore('myObjectStore', { keyPath: 'id' });
  objectStore.createIndex('name', 'name', { unique: false });
};

request.onsuccess = function(event) {
  let db = event.target.result;
  // 数据库打开成功后的操作
};

request.onerror = function(event) {
  console.error('Database error: ' + event.target.errorCode);
};

let transaction = db.transaction(['myObjectStore'], 'readwrite');
let objectStore = transaction.objectStore('myObjectStore');
let request = objectStore.add({ id: 1, name: 'Alice' });

request.onsuccess = function(event) {
  console.log('Data added successfully');
};

request.onerror = function(event) {
  console.error('Error adding data: ' + event.target.errorCode);
};

let transaction = db.transaction(['myObjectStore'], 'readonly');
let objectStore = transaction.objectStore('myObjectStore');
let request = objectStore.get(1);

request.onsuccess = function(event) {
  console.log('Data retrieved:', request.result);
};

request.onerror = function(event) {
  console.error('Error retrieving data: ' + event.target.errorCode);
};

let transaction = db.transaction(['myObjectStore'], 'readwrite');
let objectStore = transaction.objectStore('myObjectStore');
let request = objectStore.put({ id: 1, name: 'Bob' });

request.onsuccess = function(event) {
  console.log('Data updated successfully');
};

request.onerror = function(event) {
  console.error('Error updating data: ' + event.target.errorCode);
};

let transaction = db.transaction(['myObjectStore'], 'readwrite');
let objectStore = transaction.objectStore('myObjectStore');
let request = objectStore.delete(1);

request.onsuccess = function(event) {
  console.log('Data deleted successfully');
};

request.onerror = function(event) {
  console.error('Error deleting data: ' + event.target.errorCode);
};
