<form class="form-horizontal" name="form" (ngSubmit)="!f.form.invalid && staffDetails(model)" #f="ngForm" novalidate>
<div class="form-group"><button [disabled]="f.invalid" *ngIf ="buttonSave" class="btn btn-info">Save</button></div>
When the submit button is clicked, the page does not refresh and subsequent resubmissions do not fetch values.
When you perform a reset, it will clear the entire form and revert its state back to pristine, without triggering any validations. On the other hand, using resetForm will only clear the values without changing the form's state. Source
This decision should be made based on the specific requirements.
HTML File
<form #f="ngForm" (ngSubmit)="onSubmit(f)">
TypeScript File
protected onSubmit(f: NgForm): void {
// Add your code here
f.resetForm(); or f.reset();
}
Pass the form instance defined as f to the submit function in order to reset the form.
Source
Utilizing HTML Component
To implement the functionality, include #f="ngForm" within the form tag
<form class="form-horizontal" name="form" (ngSubmit)="!f.form.invalid
&& staffDetails(model)" #f="ngForm" novalidate>
<!-- form inputs -->
</form> <!-- form closed>
Implementation in Logic Component (TS File)
import { ViewChild } from '@angular/core';
@ViewChild('f') myForm; //obtain reference of form using ViewChild property
Once declared, reset the form with the reset function as follows
staffDetails(data){
this.myForm.resetForm(); //resetting the form
}

Utilize the reset() function.
Give this a shot:
this.myform.reset();
If you are working with template driven forms, follow these steps:
Utilize the (ngSubmit) event to manage the form submission. Include the form as a parameter in the event handler. For example: (ngSubmit)="onFormSubmit(f)
In your component's HTML file
<form class="form-horizontal" name="form" (ngSubmit)="onFormSubmit(f)" #f="ngForm" novalidate>
In your component's TypeScript file
public onFormSubmit(ngForm: ngForm): void {
// !f.form.invalid && staffDetails(model)
ngForm.form.reset();
}
If you want to clear the entire form after submission, you can achieve this by using reset() in Angular. The example below demonstrates this functionality in Angular 8. Here is a subscription form where users enter their email address.
<form class="form" id="subscribe-form" data-response-message-animation="slide-in-left" #subscribeForm="ngForm"
(ngSubmit)="subscribe(subscribeForm.value); subscribeForm.reset()">
<div class="input-group">
<input type="email" name="email" id="sub_email" class="form-control rounded-circle-left"
placeholder="Enter your email" required ngModel #email="ngModel" email>
<div class="input-group-append">
<button class="btn btn-rounded btn-dark" type="submit" id="register"
[disabled]="!subscribeForm.valid">Register</button>
</div>
</div>
</form>

Angular: 8.2.11
In Template: HTML
<form #f="ngForm" [formGroup]="postForm" (keydown.enter)="$event.preventDefault()" (ngSubmit)="onSubmit(f)">

f.reset();
}
