将参数转换为可观察的序列。

of<T>(...args: (SchedulerLike | T)[]): Observable<T>

参量

returns

Observable<T>：一个 Observable，它发出上述自变量，然后完成。

描述

每个参数都将成为一个next通知。

与不同的是 from，它不会进行拼合，而是将每个参数作为单独的next通知整体发出。

例子

发射值 10, 20, 30

import { of } from 'rxjs';


of(10, 20, 30)
.subscribe(
  next => console.log('next:', next),
  err => console.log('error:', err),
  () => console.log('the end'),
);
// result:
// 'next: 10'
// 'next: 20'
// 'next: 30'

发射数组 [1,2,3]

import { of } from 'rxjs';


of([1,2,3])
.subscribe(
  next => console.log('next:', next),
  err => console.log('error:', err),
  () => console.log('the end'),
);
// result:
// 'next: [1,2,3]'
