如何只刷新组件的一部分而不刷新 angular 中的 ngOnInIt()？

Question

I need to know whether there is a way to refresh only the delete reply part without refreshing the whole component with ngOnInIt()

 public deleteReply(commentId, replyId) {
    this.isLoadingReplyDelete = true;
    this.discussionService.deleteReply(commentId, replyId).takeWhile(() => this.alive)
      .subscribe(returnObj => {
     if (returnObj.status === 200) {
      this.isLoadingReplyDelete = false;
      this.ngOnInit();
    }
   });
  }
 }

You shouldn't call ngOnInit() from another function's scope, it is part of @angular/core

You will need to provide some context (eg your template code) see you which implementation of ChangeDetectorRef would be good practice in this case, but other comments have pointed you in the right direction.
