打开模态表单,包含从ngx-formly从另一个ngx-formly形式创建的表单

我目前正在使用ngx-formly从JSON动态创建一堆Angular表单,这非常好用。我有一个特殊的用例,表单上的自定义按钮应该打开一个包含另一个表单的模式对话框,其中还包含使用ngx-formly创建的表单。我在ngx-formly网站上看到的示例使用自定义按钮,并使用.ts文件创建自定义组件,但我想避免这种情况,因为我会有几个表单执行此操作,并且我不想创建不同的组件对此。

有没有办法从ngx-formly形式触发模态对话框,用ngx-formly形式显示模态,而不必为它们创建多个组件(.ts)文件?

包含动态数据的常见引导模型

<强> modal.service.ts

import {Injectable} from '@angular/core';
import {ModalModel} from './modal.model';
import {Subject} from "rxjs/Subject";

declare let $: any;

@Injectable()
export class ModalService {

  modalData = new Subject<ModalModel>();

  modalDataEvent = this.modalData.asObservable();

  open(modalData: ModalModel) {

    this.modalData.next(modalData);

    $('#myModal').modal('show');
  }

}

<强> modal.component.ts

import { Component } from '@angular/core';
import { ModalService } from './modal.service';
import {ModalModel} from './modal.model';

declare let $: any;

@Component({
  selector: 'app-modal',
  templateUrl: './modal.component.html',
  styleUrls: [ './modal.component.css' ]
})
export class ModalComponent  {

  modalData: ModalModel;

  constructor(private modalService: ModalService) {
    this.modalService.modalDataEvent.subscribe((data) => {
      this.modalData = data;
    })
  }

}

从任何组件调用此服务

import { Component } from '@angular/core';
import { ModalService } from '../modal/modal.service';
import { ModalModel } from '../modal/modal.model';


declare let $: any;

@Component({
  selector: 'app-home',
  templateUrl: './home.component.html',
  styleUrls: [ './home.component.css' ]
})
export class HomeComponent  {

  modelData = new ModalModel();

  constructor(private modalService: ModalService) {

  }

  open() {
    this.modelData.header = 'This is my dynamic HEADER from Home component';
    this.modelData.body = 'This is my dynamic BODY from Home component';
    this.modelData.footer = 'This is my dynamic footer from Home component';
    this.modalService.open(this.modelData);
  }
}
