将类动态应用于angular自定义窗体组件

import { Component, ComponentFactoryResolver, ViewChild, ViewContainerRef } from '@angular/core';
import { CustomFormComponent } from './custom-form.component';

@Component({
  selector: 'app-parent-component',
  template: `
    <div>
      <button (click)="loadCustomForm()">加载自定义窗体</button>
      <ng-container #customFormContainer></ng-container>
    </div>
  `,
})
export class ParentComponent {
  @ViewChild('customFormContainer', { read: ViewContainerRef }) customFormContainer: ViewContainerRef;

  constructor(private componentFactoryResolver: ComponentFactoryResolver) {}

  loadCustomForm() {
    // 解析自定义窗体组件的工厂
    const customFormFactory = this.componentFactoryResolver.resolveComponentFactory(CustomFormComponent);

    // 创建自定义窗体组件实例
    const customFormComponentRef = this.customFormContainer.createComponent(customFormFactory);

    // 将类应用于自定义窗体组件
    const customFormInstance = customFormComponentRef.instance;
    customFormInstance.class = MyClass; // 设置自定义窗体组件的属性
  }
}
