      <div class="alert alert-danger" *ngIf="firstName.touched && !firstName.valid">

          <div *ngIf="firstName.errors.required">First Name is required.</div>

          <div *ngIf="firstName.errors.minlength">First Name is minimum {{ firstName.errors.minlength.requiredLength }} character.</div>

      <textarea required ngModel #comment="ngModel" name="comment" id="comment" cols="30" rows="10" class="form-control"></textarea>

      <div class="alert alert-danger" *ngIf="comment.touched && !firstName.valid">

          Comment is required.



  <button class="btn btn-primary" type="submit" [class.disabled]="!contactForm.valid">Submit</button>

In ts file. we will write submit() and get all input fields values. so let's add following code to app.component.ts file.


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


  selector: 'app-root',

  templateUrl: './app.component.html',

  styleUrls: ['./app.component.css']
