Click function for Angular bootstrap button

Click function for Angular bootstrap button

I have implemented a basic form in my template that already has validation. My main issue is how to check when the user clicks on the button after filling out all required fields?

<section class="contact-area pb-80" style="margin-top:10%">
    <div class="container">
        <div class="section-title">
            <h2>Your Information</h2>
            <div class="bar"></div>
            <p>Please provide accurate information so we can contact you accordingly.</p>
        </div>

        <div class="row h-100 justify-content-center align-items-center">
            <div class="col-lg-6 col-md-12">
                <img src="assets/img/1.png" alt="image">
            </div>

            <div class="col-lg-6 col-md-12">
                <form id="contactForm">
                    <div class="row">
                        <div class="col-lg-12 col-md-12">
                            <div class="form-group">
                                <input type="text" name="name" id="name" class="form-control" required placeholder="Enter your name">
                            </div>
                        </div>

                        <div class="col-lg-12 col-md-12">
                            <div class="form-group">
                                <input type="email" name="email" id="email" class="form-control" required placeholder="Enter your email">
                            </div>
                        </div>

                        <div class="col-lg-12 col-md-6">
                            <div class="form-group">
                                <input type="text" name="phone_number" id="phone_number" required class="form-control" placeholder="Enter your number (Whats app)">
                            </div>
                        </div>

                        <div class="col-lg-12 col-md-6">
                            <div class="form-group">
                                <input type="text" name="msg_subject" id="msg_subject" class="form-control" required placeholder="Enter your skype name">
                            </div>
                        </div>


                        <div class="col-lg-12 col-md-12">
                            <button type="submit" class="btn btn-primary">Send Message</button>
                        </div>
                    </div>
                </form>
            </div>
        </div>
    </div>
</section>

My challenge lies in determining how to trigger the function I created, submit(), only when all form fields are filled before the user clicks on the Send Message button.

The current approach I've attempted involved adding (click)="submit()" to the button. However, this causes the function to be called every time the button is clicked. I specifically need it to execute only when all required fields are completed.

Template Example:

<form #myForm="ngForm">
  <input ngModel name="username" type="text" required />
  <input ngModel name="user-email" type="email" required />
  <input ngModel name="user-phone" type="text" required />

  <button (click)="submitForm(myForm)">Submit</button>
</form>

Component Logic:

submitForm(form: NgForm) {
  console.log(form.invalid);
}

Remember to import FormsModule in your module:

import { FormsModule } from '@angular/forms';

@NgModule({
  // ...
  imports: [..., FormsModule, ...],
  // ...
})

Ensure to include the following code in your app-module by importing { FormsModule } from '@angular/forms' and adding it to the imports array.

@NgModule({
  imports: [FormsModule],
})

In your form element, create a template variable called myForm, and on the button tag, utilize property binding like [disabled]="!myForm.form.valid". This will only enable the Submit button when all form elements are filled out correctly.

Template file:

<form #myForm="ngForm" method="POST" (ngSubmit)="submitForm(myForm)">
  <div>
    <label>Name</label>        
    <input name="name" type="text" required ngModel/>
  </div>
  <div>
    <label>Email</label>
    <input name="email" type="email" required ngModel/>
  </div>
  <div>
    <label>Phone no</label>
    <input name="phone" type="number" required ngModel/>
  </div>

  <button type="submit" [disabled]="!myForm.form.valid">Submit</button>
  <pre>{{myForm.value | json}}</pre>
</form>
