如何在 Web 站点的 Firebase 中添加新用户和新参考（HTML，JS）

Question

我在网上找到了一个解决方案，但它是针对旧版本的Firebase，现在它每隔一段时间就可以工作或根本不工作。 我有一个简单的 Html 网站，内容如下：

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <meta http-equiv="X-UA-Compatible" content="IE=edge">
    <meta name="    viewport" content="width=device-width, initial-scale=1.0">

<script src="https://www.gstatic.com/firebasejs/8.2.7/firebase-app.js"></script>
<script src="https://www.gstatic.com/firebasejs/8.2.7/firebase-auth.js"></script>
<script src="https://www.gstatic.com/firebasejs/8.2.7/firebase-database.js"></script>
<script src="form.js"></script>
    <title>Login System</title>
</head>
<body>
    <div class="formContainer" align="center">
       
        <label>Email:</label>
        <input type="email" placeholder="Email" id="email"><br>
        <label>Password</label>
        <input type="password" placeholder="Password" id="password"><br>
        <label>Name</label>
        <input type="text" placeholder="Name" id="FIO"><br>
        <label>position</label>
        <input type="text" placeholder="position" id="DOLZH"><br>
        <label>Place of work </label>
        <input type="text" placeholder="Place of work" id="Workplace"><br>
        <label>Tab number</label>
        <input type="text" placeholder="Tab number" id="TabNumber"><br>
        <button onclick="signUp()" id="signUp">Create User</button>
    </div>
</body>
</html>

我有 JavaScript：

  //firebaseConfig has my correct data
  var firebaseConfig = {
    apiKey: "",
  authDomain: "",
  databaseURL: "",
  projectId: "",
  storageBucket: "",
  messagingSenderId: "",
  appId: "",
  measurementId: ""
  };
  // Initialize Firebase
  firebase.initializeApp(firebaseConfig);

  const auth =  firebase.auth();

  //signup function
  function signUp(){
    var email = document.getElementById("email");
    var password = document.getElementById("password");
    const username=document.getElementById("email").value.split("@",1);
    var messageRef=firebase.database().ref(username[0])
    const fiouser=document.getElementById("FIO").value;
    const work=document.getElementById("Workplace").value;
    const tabnum=document.getElementById("TabNumber").value;
    const dolzhnost=document.getElementById("DOLZH").value;
    var errorcount=0;
    var promise = auth.createUserWithEmailAndPassword(email.value,password.value);
    promise.catch(e=>alert(e.message));
    
    if (errorcount==0){
    try{
                var newMessageRef=messageRef;
                newMessageRef.set({
                "*Должность":dolzhnost,
                "*Место работы":work,
                "*Табельный номер":tabnum,
                "*ФИО":fiouser,
                })
            }
            catch(e){
                alert(e.message);
            }
    }
    if (errorcount==0){
        alert("Пользователь успешно зарегистрирован!")
        location.reload();
    }   
  }

有谁知道将用户添加到 Firebase Auth 并为新版本添加对 Firebase 实时数据库的新参考的方法？:) PS 我知道我的 JS 脚本不好:)
