小编bul*_*rce的帖子

我是rxjs的新手,只是想知道通过管道流并点击它来设置类属性是可以的,或者它应该在订阅中进行.对我来说无论哪种方式都有效,只是想知道是否可以按照我认为合适的方式做到这一点,或者有一些我不知道的事情.

打字稿代码演示两种方式:

export class ViewComponent implements OnInit {

  applicant = {};

  constructor(public route: ActivatedRoute, private store: Store<any>) {}

  ngOnInit() {
    this.route.paramMap.pipe(
      switchMap(params => this.store.select(state => state.applicants.entities[params.get('id')])),
      tap(applicant => this.applicant = applicant)
    ).subscribe();
  }
}

VS

export class ViewComponent implements OnInit {

  applicant = {};

  constructor(public route: ActivatedRoute, private store: Store<any>) {}

  ngOnInit() {
    this.route.paramMap.pipe(
      switchMap(params => this.store.select(state => state.applicants.entities[params.get('id')]))
    ).subscribe(applicant => this.applicant = applicant);
  }
}
