如何将格式化的值显示为用户类型，但将原始值发送到Angular 4 formControl进行验证和formControl值？

import { Pipe, PipeTransform } from '@angular/core';

@Pipe({
  name: 'formatValue'
})
export class FormatValuePipe implements PipeTransform {
  transform(value: any): any {
    // 根据需要进行格式化操作
    // 返回格式化后的值
  }
}

<p>格式化值: {{ originalValue | formatValue }}</p>

import { Component } from '@angular/core';
import { FormControl } from '@angular/forms';

@Component({
  selector: 'app-form',
  template: `
    <form [formGroup]="myForm">
      <input type="text" formControlName="myControl">
    </form>
  `
})
export class MyFormComponent {
  myForm = new FormGroup({
    myControl: new FormControl()
  });
}

import { Component } from '@angular/core';
import { FormControl } from '@angular/forms';

@Component({
  selector: 'app-form',
  template: `
    <form [formGroup]="myForm">
      <input type="text" formControlName="myControl">
    </form>
  `
})
export class MyFormComponent {
  myForm = new FormGroup({
    myControl: new FormControl()
  });

  setOriginalValue(originalValue: any) {
    this.myForm.get('myControl').setValue(originalValue);
  }
}
