// 初始化 Firebase
const firebaseConfig = {
  apiKey: "YOUR_API_KEY",
  authDomain: "YOUR_PROJECT_ID.firebaseapp.com",
  databaseURL: "https://YOUR_PROJECT_ID.firebaseio.com",
  projectId: "YOUR_PROJECT_ID",
  storageBucket: "YOUR_PROJECT_ID.appspot.com",
  messagingSenderId: "YOUR_MESSAGING_SENDER_ID",

firebase.initializeApp(firebaseConfig);

// 获取要删除的数据节点的引用
const databaseRef = firebase.database().ref('path/to/your/data');

// 给按钮添加点击事件监听器
document.getElementById('deleteButton').addEventListener('click', function() {
  // 删除数据节点
  databaseRef.remove()
    .then(function() {
      console.log("数据删除成功");
    })
    .catch(function(error) {
      console.error("数据删除失败:", error);
