Start Validating after button click

Validating after button click

There is a simpler way of achieving the same result as our second example without iterating all the form controls and marking them as touched (or dirty).

Since we have a new variable to help us verifying if we need to display the validation messages or not, we also need to change the expression that returns if a field is valid or not: In this case, we add a new condition to the field validation.

Nothing mentioned prior to that worked; I didn't try anything mentioned after.

It seems to be the simplest solution and makes sense (don't take any action on a pristine field) -- unless you're using does work for me.

In this article we will learn different approaches of validating all form fields when user clicks on submit button for Angular Reactive Forms.
