Angular

In this tutorial, we will learn template-driven form validation in Angular. It is very common that the users will make mistakes when filling out the web form. This is where the validations come into play. The validation module must ensure that the user has provided accurate and complete information in the form fields. We must display the validation error messages to the users, disable the submit button until validation. In this tutorial, we will look at how validations are handled in Template-driven forms in Angular and learn how to use the Angular built-in validators.

In this tutorial, we will learn how to set value in template-driven forms in Angular. We will learn how to set the default or initial value to form controls, dynamically set values, reset the value of the form, etc. Learn how to set the value of individual FormControl or a FormGroup and nested FormGroup.

Angular Template-driven Forms is one of the two ways of building forms in Angular. In this tutorial, we will learn how to build a simple Template-driven forms example app. First, we build a simple HTML form using a few form elements. The ngForm directive will convert it to the Template-driven form and create the top-level FormGroup control. Next, we use the ngModel directive to create the FormControl instance for each of the HTML form elements. Later, we will learn how to submit the form data to the component class. We will also learn how to initialize or reset the form data and use the data binding to access the data in the component class.
