console.log(email, password);
};
return (
<form onSubmit={handleSubmit}>

<input type="email" formControlName="email">
<input type="password" formControlName="password">
<button type="submit" [disabled]="!registrationForm.valid">Register</button>
</form>
`
})
export class RegistrationFormComponent {
registrationForm = new FormGroup({
email: new FormControl('', [Validators.required, Validators.email]),
password: new FormControl('', [Validators.required, Validators.minLength(5)])
});
onSubmit() {
console.log(this.registrationForm.value);
}
}
5. Vue.js Forms
