What is the benefit of utilizing ngSubmit over just using a basic button and function?

Lately, I've been pondering whether to utilize ngSubmit or simply bind a (click)="submit()" on a button.

There's been much debate about using submit and ngSubmit, but is it necessary to rely on the traditional HTML submit method? Particularly when sometimes it's not even a POST request but rather a PATCH for updating forms. Forms are becoming more complex nowadays with nested forms or components containing subforms within the main form by passing the FormGroup to child components.

If I opt for ngSubmit, should I only apply it to the parent form or all forms? I find myself puzzled about the advantages of ngSubmit in comparison to a basic button with a click event handler triggering a submit function with an http.post() call, especially when working with reactive forms and having easy access to form controls and validators within my FormGroup object.

Answer №1

If you have it on the main form, that should suffice if you plan to submit all your forms together. A great feature of ngSubmit is that it maintains the user experience of submitting. The submission will occur when a button with the submit type is clicked (no need for a (click) event), or when Enter is pressed in an input field within your form.

Answer №2

Utilizing ngsubmit with a submit button or using a button to call a method that references the instance of the form model may seem indistinguishable. However, employing the first approach is considered best practice and is more prevalent among developers. Collaborators working on your code are likely to look for the ngsubmit method when navigating your codebase.
