Как получить все значения текстового поля из HTML в компоненте Angualr

-2

Я успешно получаю данные из webapi и могу показать на HTML-странице angularjs2, как показано ниже

    <div>
        <br />
        <br />
        <div style="text-align: center;">

            <h4>Employee Personal Information</h4>
        </div>
        <div style="text-align: right;">
            <label class="InformationTextColor">{{EmployeeName}}({{EmployeeCode}})</label>
        </div>
        <div style="text-align: center;">
            <table id="tblEnquire1" style="margin-left:50px;" class="table table-hover table-bordered table-striped table-responsive" border="1">

    </div>

но как только я редактирую несколько значений текстового поля, после нажатия кнопки не удается получить все значения текстового поля (отредактированные значения) в компоненте. Событие щелчка - это PostPersonalInformation()

import { Component, Input, OnInit,Output,EventEmitter } from '@angular/core';
import { IEmployeePersonalInformation } from './PersonalInforamtion';
import { EmployeeService } from './PersonalInformationService';
import { IPersonalDetailsInterface } from './PersonalInforamtion';


@Component({
    selector: 'list-employee',
    templateUrl: 'app/PersonalInformation/PersonalInformation.component.html',
    styleUrls:['app/PersonalInformation/PersonalInformation.css'],
    providers: [EmployeeService]
})
export class EmployeeListComponent implements OnInit {
    employees: IEmployeePersonalInformation;
     PersonalInformation: IPersonalDetailsInterface
    selectedvalue: string;
    firstarray: number = 0;
    EmployeeCode: string;
    EmployeeName: string;
    posting: string;


    constructor(private _employeeService: EmployeeService) { }

    PostPersonalInformation(): void
    {
        console.log("Hey this is post" + this.employees);
        console.log("Hey this is post" + this.EmployeeName);
        this.firstarray = 0;
        for (let personaldata in this.employees) {
            if (this.firstarray == 0) {

                this.firstarray = 1;
                console.log(this.employees[personaldata]);
            }

        }


        this._employeeService.PostPersonalInformation(this.employees);

    }

    ngOnInit() {
        this._employeeService.getEmployees()
            .subscribe((employeeData) => {
            this.employees = employeeData;

            });

        this._employeeService.getPersonalInformationList()
            .subscribe((employeeData1) => {
                this.PersonalInformation = employeeData1;
                console.log(employeeData1);
                for (let personaldata in employeeData1)
                {
                    if (this.firstarray == 0)
                    {
                        this.selectedvalue = employeeData1[personaldata][0]['BankCode'];
                        this.EmployeeCode = employeeData1[personaldata][0]['EmployeeCode'];
                        this.EmployeeName = employeeData1[personaldata][0]['EmployeeName'];
                        this.posting = employeeData1[personaldata][0]['PostingCode'];
                        this.firstarray = 1;
                        console.log(employeeData1[personaldata][0]['PostingCode']);
                         }

                }


            });
    }

}

Вы можете создать сервис, используя HttpClient, как это (я издеваюсь над API, получая файл JSON)

 @Injectable()
    export class ConfigService {

      constructor(private http: HttpClient) { }

      getData() {
        return this.http.get('/assets/config.json');
      }
    }

Используйте сервис в вашем компоненте

export class AppComponent {
  myresult: any;
  name = "Display data from service";
  constructor(private config: ConfigService) { }

  ngOnInit() {
    this.config.getData()
      .subscribe((result: any) => {

        this.myresult = result.PersonalInfolistModel;
        console.log(this.myresult)
      });
  }
}

И выведите свое значение, используя ngFor в HTML

<p *ngFor="let item of myresult">{{item.EmployeeName}}</p>
