Angular Form Validation - Pristine, Dirty, Touched and Status | Complete Angular Tutorial
Angular Tutorial: Here, you will learn Angular Form Validation - Pristine, Dirty, Touched, and Status.
Angular is a popular framework for building web applications, and it includes a powerful form validation system. When working with forms in Angular, there are four important concepts to understand: pristine, dirty, touched, and status.
Pristine: A form control is considered pristine if the user has not interacted with it yet. In other words, the control has not been modified by the user. A control is marked as pristine by default.
Dirty: A form control is considered dirty if the user has interacted with it and made changes. In other words, the control has been modified by the user.
Touched: A form control is considered touched if the user has interacted with it and then moved focus away from it. In other words, the control has been visited by the user.
Status: The status of a form control refers to its current validation state. A control can have one of several possible statuses, including valid, invalid, pending, or disabled. These statuses are based on the validators that have been applied to the control.
Understanding these concepts is crucial when building forms in Angular. By leveraging the power of Angular's form validation system, you can create robust, user-friendly forms that help prevent errors and improve the overall user experience.
