javascript - 数据不会在 javascript 中进入 firebase 数据库

问题描述

这里我使用的是firebase auth，所以我还将用户提供的数据上传到firebase实时数据库中，但我的数据只有在服务器启动时才会发送一次，如果我在启动serer时一次性添加更多用户然后数据不会进入火力基地，甚至不会显示任何错误，工作顺利。一个警告即将到来。

我不知道问题出在哪里，因为 user.uid 也打印得很好，用户名也打印得很好。

这是我的代码

这可能是因为您将submit类型分配给按钮：您的表单是在触发 Firebase 方法之前提交的。createUserWithEmailAndPassword()

您应该将按钮类型更改为button（有关按钮类型的更多详细信息，请参见W3 规范）。

类似于以下内容（未经测试）：

    <form id="signup">
        //...
        <button type="button" id="signupButton">Sign up</button>

    </form>


    //...

<script>
    var firebaseConfig = {
      //...
    };
    // Initialize Firebase
    //...

    document
        .getElementById("signupButton")
        .addEventListener("click", function() => {...})
