angular - Angular 上的 ForkJoin 问题

Question

我为测试 forkJoin 编写了此代码，但它不起作用! 你能检查一下是什么问题吗？

const observables = [];

observables.push(new Observable(subscriber => subscriber.next('Hello')));
observables.push(new Observable(subscriber => subscriber.next(' ')));
observables.push(new Observable(subscriber => subscriber.next('World') ));
observables.push(new Observable(subscriber => subscriber.next('!')));

forkJoin(observables).subscribe(word => console.log(word.join('')));

Answer 1

试试这个

const observables = [];

observables.push(Observable.of('Hello'));
observables.push(Observable.of(' '));
observables.push(Observable.of('World'));
observables.push(Observable.of('!'));

Observable.forkJoin(observables).subscribe(word => console.log(word.join('')));
