问题描述

这是一个快速的问题。我已经使用RxJS 5几个月了,而且我遇到了一些我并不理解的行为,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.

我的情况是只用订阅一个可观察链.subscribe(); 不会触发observable。

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onNext回调(空或不),可观察触发器和链过程: .subscribe(()=> {});

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

有人可以解释为什么会出现这种情况吗?

Can anyone explain why this behavior happens?
