Rxjs主题next或onNext [英] Rxjs Subject next or onNext

问题描述

在rxjs方面，我是新手，请耐心等待. 例如在本教程中 http://blog.angular-university.io/how-to-build-angular2-apps-using-rxjs-observable-data-services-pitfalls-to-avoid/ 但是我在ng-book中看到了相同的代码

I'm quite new at rxjs stuff be patience. For example in this tutorial http://blog.angular-university.io/how-to-build-angular2-apps-using-rxjs-observable-data-services-pitfalls-to-avoid/ but I saw the same code in the ng-book

我可以看到

let subject = new Rx.Subject();
subject.subscribe(value => console.log('Received new subject value: '))
subject.next(newValue);

但是如果我将代码放入浏览器中，我就拥有

but if I put the code in the browser I've got

s ubject.next不是函数

所以，如果我看一下文档 https://github.com/Reactive-Extensions/RxJS/blob/master/doc/gettingstarted/subjects.md

so if I take a look to the doc https://github.com/Reactive-Extensions/RxJS/blob/master/doc/gettingstarted/subjects.md

var subject = new Rx.Subject();
subject.subscribe(value => console.log('Received new subject value: ',value))
subject.onNext(2);

您能解释一下为什么教程和书吗 正在使用下一个吗?我想念什么?

Can you explain me why the tutorial and the book are using next ? What am I missing ?

推荐答案

似乎您使用了错误的rxjs版本(4.x). Angular2使用rxjs 5 https://github.com/ReactiveX/rxjs/
