使用javascript在firebase中自动递增一个值

<script src="https://www.gstatic.com/firebasejs/9.5.0/firebase-app.js"></script>
<script src="https://www.gstatic.com/firebasejs/9.5.0/firebase-database.js"></script>

const firebaseConfig = {
  apiKey: "YOUR_API_KEY",
  authDomain: "YOUR_AUTH_DOMAIN",
  databaseURL: "YOUR_DATABASE_URL",
  projectId: "YOUR_PROJECT_ID",
  storageBucket: "YOUR_STORAGE_BUCKET",
  messagingSenderId: "YOUR_MESSAGING_SENDER_ID",
  appId: "YOUR_APP_ID"
};

firebase.initializeApp(firebaseConfig);

const database = firebase.database();

const counterRef = database.ref("counter");

counterRef.transaction((currentValue) => {
  // 如果当前值不存在，则初始化为0
  if (currentValue === null) {
    return 0;
  }

  // 否则，将值递增1
  return currentValue + 1;
}, (error, committed, snapshot) => {
  if (error) {
    console.error("事务执行失败：", error);
  } else if (committed) {
    console.log("事务执行成功，新值为：", snapshot.val());
  } else {
    console.log("事务被中止。");
  }
});
