有没有角度为2或更高的@ angular -libphonenumber的示例？

npm install @angular-libphonenumber

import { Component } from '@angular/core';
import { PhoneNumberUtil, PhoneNumberFormat } from '@angular-libphonenumber';

@Component({
  selector: 'app-example',
  template: `
    <input [(ngModel)]="phoneNumber" placeholder="Enter phone number">
    <button (click)="validatePhoneNumber()">Validate</button>
    <p>Formatted phone number: {{ formattedPhoneNumber }}</p>
  `
})
export class ExampleComponent {
  phoneNumber: string;
  formattedPhoneNumber: string;

  validatePhoneNumber() {
    const phoneNumberUtil = PhoneNumberUtil.getInstance();
    const phoneNumber = phoneNumberUtil.parse(this.phoneNumber, 'US');

    if (phoneNumberUtil.isValidNumber(phoneNumber)) {
      this.formattedPhoneNumber = phoneNumberUtil.format(phoneNumber, PhoneNumberFormat.NATIONAL);
    } else {
      this.formattedPhoneNumber = 'Invalid phone number';
    }
  }
}
