如何在bootstrap 4.3.1和angular 8中使用表单验证

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

@Component({
  selector: 'app-your-component',
  templateUrl: './your-component.html',
  styleUrls: ['./your-component.css']
})
export class YourComponent {
  myForm: FormGroup;

  constructor() {
    this.myForm = new FormGroup({
      name: new FormControl('', Validators.required),
      email: new FormControl('', [Validators.required, Validators.email]),
      password: new FormControl('', [Validators.required, Validators.minLength(6)])
    });
  }
}

<form [formGroup]="myForm" (ngSubmit)="onSubmit()">
  <div class="form-group">
    <label for="name">Name</label>
    <input type="text" class="form-control" id="name" formControlName="name">
    <div *ngIf="myForm.get('name').invalid && myForm.get('name').touched" class="text-danger">
      Name is required.
    </div>
  </div>
  
  <div class="form-group">
    <label for="email">Email</label>
    <input type="email" class="form-control" id="email" formControlName="email">
    <div *ngIf="myForm.get('email').invalid && myForm.get('email').touched" class="text-danger">
      Email is required and must be a valid email address.
    </div>
  </div>
  
  <div class="form-group">
    <label for="password">Password</label>
    <input type="password" class="form-control" id="password" formControlName="password">
    <div *ngIf="myForm.get('password').invalid && myForm.get('password').touched" class="text-danger">
      Password is required and must be at least 6 characters long.
    </div>
  </div>
  
  <button type="submit" class="btn btn-primary">Submit</button>
</form>

onSubmit() {
  if (this.myForm.valid) {
    // 表单验证通过，可以进行提交操作
    console.log(this.myForm.value);
  } else {
    // 表单验证不通过，显示错误信息
    alert('Please fill in all required fields correctly.');
  }
}
