我有一个组件，让我们说它叫做"Form"，旁边还有另一个组件，我们可以称之为"Filing Lists"。

“ Form”是“NbWindowService”，“Filing Lists”是“ng2-smart-table”的“LocalDataSource”。现在我想要的是，在“表单”完成或销毁后，“归档列表”必须像我在文档中阅读的内容一样更新/刷新。如何正确地做到这一点？

加班-form.component.ts

import { Component, OnInit } from '@angular/core';
import { NbAuthJWTToken, NbAuthService } from '@nebular/auth';
import { OvertimeService } from '../../services/overtime.service';
import { Overtime } from '../../models/overtime.model';

@Component({
  selector: 'ngx-overtime-form',
  templateUrl: './overtime-form.component.html',
  styleUrls: ['./overtime-form.component.scss']
})
export class OvertimeFormComponent implements OnInit {
  showMessages: any = {};
  user: any;
  overtime: Overtime = {
    //some model values instantiation
  };

  constructor(private overtimeService: OvertimeService,
    private authService: NbAuthService) {

    this.authService.onTokenChange()
      .subscribe((token: NbAuthJWTToken) => {
        if (token.isValid()) {
          this.user = token.getPayload();
          this.overtime.employee_id = this.user.employee_id;
        }
      });
  }

  fileOvertime() {
    this.showMessages = {};
    this.overtimeService.overtimeFiling(this.overtime).subscribe(
      (result) => {
        this.showMessages.success = result
        this.overtime.employee_id = this.overtime.employee_id;
      }, (err) => {
        this.showMessages.error = err.error;
        this.overtime.employee_id = this.overtime.employee_id;
      }
    )
  }

  ngOnInit() {
  }

}

只需创建一个订阅服务的load()方法和使用ng2-smart-table的方法。

fetchTableData(){
    this.service.getOvertime().subscribe(data => {
      this.source.load(data as []);
    });
}

之后，openOvertimeForm()通过订阅 windowRef 的onClose状态来更新您的方法。

openOvertimeForm() {
    this.windowRef = this.windowService.open(OvertimeFormComponent, { title: `File Overtime` });
    this.windowRef.onClose.subscribe(() => {
      this.fetchTableData();
    })
}
