我已尝试过所有内容,但它似乎无法将数据保存到数据库中。这是我的示例代码html:
<div class="form-body">
<div class="form-row">
<div class="form-controls">
<input type="text" name="emails" class="field" id="email" placeholder="Email Address">
</div><!-- /.form-controls -->
</div><!-- /.form-row -->
<div class="form-row">
<div class="form-controls">
<input type="text" name="names" class="field" id="name" placeholder="Names (First, Middle, Last)">
</div><!-- /.form-controls -->
</div><!-- /.form-row -->
<div class="form-row">
<div class="form-controls">
<input type="number" name="phonenumber" id="number" class="field" placeholder="Phonenumber">
</div><!-- /.form-controls -->
</div><!-- /.form-row -->
<div class="form-row">
<div class="form-controls">
<input type="text" name="countries" id="country" class="field" placeholder="Country">
</div><!-- /.form-controls -->
</div><!-- /.form-row -->
<div class="form-row">
<div class="form-controls">
<input type="text" name="usernames" id="username" class="field" placeholder="Username">
</div><!-- /.form-controls -->
</div><!-- /.form-row --><div align="center">
<button onclick="saveData()" id="submit" >Register</button>
<br />
<span id="loading_image" style="display: none;">
<img src="../images/ajax-loader.gif" alt="Please Wait" width="20" height="11"/> </span>
</div>
这就是我在html代码体中初始化firebase的方式:
<script src="https://www.gstatic.com/firebasejs/4.1.3/firebase.js"></script>
<script>
var config = {
apiKey: "AIzaSyBNz5xZ-yLqvTum93rEo2cVYtlJXSyUteg",
authDomain: "kafe-f422b.firebaseapp.com",
databaseURL: "https://kafe-f422b.firebaseio.com",
projectId: "kafe-f422b",
storageBucket: "kafe-f422b.appspot.com",
messagingSenderId: "491174380565"
};
firebase.initializeApp(config);
</script>
<script src="js/register.js"></script>
<!-- jQuery library -->
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.2.1/jquery.min.js"></script>
<!-- Latest compiled JavaScript -->

我把javascript代码用于将数据保存到名为register.js的javascript文件中的firebase。这是代码:
var user_email = document.getElementById('email');
var user_name = document.getElementById('name');
var user_phonenumber = document.getElementById('number');
var user_country = document.getElementById('country');
var user_username = document.getElementById('username');
var user_submit = document.getElementById('submit');
$('#submit').click(function() {
var cemail = user_email.value;
var cname = user_name.value;
var cnumber = user_phonenumber.value;
var cusername = user_username.value;
var ccountry = user_country.value;
console.log('email is', cemail);
console.log('name is', cname);
var myRef = firebase.database().ref('register');
key=myRef.push().key;
var newData={
id:key,
email:cemail,
name:cname,
country:ccountry,
username:cusername,
phone_number:cnumber
}
myRef.push(newData);
});
请帮我解决这个问题,我已经尝试过阅读firebase中的所有文档,但我似乎无法将数据保存到数据库中。
答案 0 :(得分:0)
删除key = ...
行并使用myRef.push(newData).then(function (snapshot) {})
。
push
方法返回一个承诺。
还要确保您的数据库规则允许您从该路径中读取。
