Email Validation in Angular 7
Are you using Angular 7 and looking to validate email inputs in your forms? Look no further! In this article, we will explore the EmailValidator class and its implementation in Angular 7.
What is Email Validation?
Email validation is the process of checking if an email address is valid and formatted correctly. This is important in form submissions and user sign-ups to ensure that the email address entered is accurate and can be used for communication.
Email Validation in Angular 7
Angular 7 provides a built-in EmailValidator class that can be used to validate email inputs in your forms. This class implements the ValidatorFn interface, which requires the implementation of a validate
method.
The validate
method takes a control
parameter, which is of type AbstractControl
. This parameter represents the form control being validated. The method returns a ValidationErrors
object if the validation fails, or null
if the validation succeeds.
The EmailValidator class can be used in conjunction with other validators to create a custom validation function for your form controls.
Implementing Email Validation in Angular 7
To implement email validation in Angular 7, first import the EmailValidator
class from the @angular/forms
module:
import { EmailValidator } from '@angular/forms';
emailValidator(control: AbstractControl): ValidationErrors | null {
return EmailValidator.validate(control);
}
this.myForm = this.fb.group({
email: ['', [Validators.required, this.emailValidator]]
});
