我想从Javascript获取值到HTML表单以提交到Firebase数据库

<form id="myForm">
  <input type="text" id="nameInput" placeholder="Name">
  <input type="email" id="emailInput" placeholder="Email">
  <button type="submit">Submit</button>
</form>

document.getElementById('myForm').addEventListener('submit', submitForm);

function submitForm(event) {
  event.preventDefault(); // 阻止表单的默认提交行为

  // 获取表单中输入字段的值
  var name = document.getElementById('nameInput').value;
  var email = document.getElementById('emailInput').value;

  // 创建一个对象来存储要提交到Firebase的数据
  var formData = {
    name: name,
    email: email
  };

  // 调用Firebase的API将数据提交到数据库
  firebase.database().ref('users').push(formData);

  // 清空表单字段的值
  document.getElementById('nameInput').value = '';
  document.getElementById('emailInput').value = '';
}
