RXJS 5 .subscribe() 不带参数 [英] RXJS 5 .subscribe() without arguments

问题描述

所以一个快速的问题.我已经使用 RxJS 5 几个月了，我遇到了一些我不太了解的行为，因为我无法在任何地方查找它.

So a quick question. I've been using RxJS 5 for a few months now, and I've run into a bit of behavior that I don't really understand, as I haven't been able to look it up anywhere.

我的情况是，使用简单的 .subscribe(); 订阅可观察链不会触发可观察.

I'm in a situation where subscribing to an observable chain with simply .subscribe(); doesn't trigger the observable.

但是，如果我添加一个 onNext 回调(是否为空)，可观察触发器和链处理:.subscribe(() => {});

However, if I add an onNext callback (empty or not), the observable triggers, and the chain processes: .subscribe(() => {});

谁能解释为什么会发生这种行为?

Can anyone explain why this behavior happens?
