超级基本Firebase错误，“Firebase未定义” [英] Super basic Firebase error, "Firebase is not defined"

问题描述

我正在进入Firebase。但是第一天，我被一个简单的班轮难住了。

$ b 这是从演示版本开始：

var myDataRef = new Firebase（'

<这是来自演示链接，但是我在控制台中为我创建的任何Firebase数据库获得完全相同的响应。这可能是非常简单的，只是想把我的大脑包围在Firebase上，这与十年前在SQL世界里的情况有很大不同。

感谢指点。如果您将Firebase JavaScript客户端作为脚本加入，您将只能访问Firebase：

 < script src =https://cdn.firebase.com/js/client/2.4.0/firebase.js> ;< /脚本> 
  

这将使 Firebase 对象可能其他人）可用于您的脚本。

我建议您从这个 Firebase的5分钟互动教程。添加脚本标签在第1步解释。

昨天有一个类似的问题：
未捕获的ReferenceError：未定义Firebase

I'm making the move into Firebase. But Day One I'm stumped with a simple one liner.

This is right from the demo:

var myDataRef = new Firebase('https://un2ubl6u7zs.firebaseio-demo.com/');

And returns in my Chrome Console:

This is from the demo link, but I get exactly the same response in the console for any firebase DB I create. It's probably something REALLY simple, just trying to wrap my brain around Firebase, it's very different coming from a decade in the SQL world.

Thanks for pointers. :-)

解决方案

You will only have access to Firebase, if you include the Firebase JavaScript client as a script:

<script src="https://cdn.firebase.com/js/client/2.4.0/firebase.js"></script>

This will make the Firebase object (and may others) available to your script.

I recommend that you start with this 5-minute interactive tutorial for Firebase. Adding the script tag is explain in step 1 there.

There was a similar question yesterday: Uncaught ReferenceError: Firebase is not defined
