Javascript ReferenceError：在src中添加Rx.js时未定义Observable

Question

I am trying to get observables to work on my html but I keep getting this error: 我正在尝试使可观察的东西在我的html上工作，但我不断收到此错误：

ReferenceError: Observable is not defined ReferenceError：未定义Observable

I am using Firefox version: 62.0 我正在使用Firefox version: 62.0

Here is the code: 这是代码：

 <!doctype html> <html lang="en"> <head> <meta charset="utf-8"> <script type="text/javascript" src="https://cdnjs.cloudflare.com/ajax/libs/rxjs/5.4.0/Rx.js"></script> <script> const numberObservable = new Observable((observer) => { observer.next(5); observer.next(10); }); numberObservable.subscribe(value => console.log(value)); </script> <title></title> </head> <body> </body> </html>

How can I get this to work? 我该如何工作？

Answer 1

You just need to use Rx.Observable instead of simply Observable . 您只需要使用Rx.Observable而不是简单的Observable 。

 <!doctype html> <html lang="en"> <head> <meta charset="utf-8"> <script type="text/javascript" src="https://cdnjs.cloudflare.com/ajax/libs/rxjs/5.4.0/Rx.js"></script> <script> const numberObservable = new Rx.Observable((observer) => { observer.next(5); observer.next(10); }); numberObservable.subscribe(value => console.log(value)); </script> <title></title> </head> <body> </body> </html>

Answer 2

它应该是new Rx.Observable注意命名空间。
