Angular 5/4 Email Validation Regex - Model Driven Form

In this Article, we will see “How Angular 5/4 forms are used or create?”  There are basically two types of Angular forms (login) and its validations.
ü  Template driven form
ü  Model driven forms
And In this section, I will discuss about Model driven form.

Steps 1 - In the NgModule
import { FormsModule, ReactiveFormsModule } from '@angular/forms';


Steps 2 - Create login form
<form [formGroup]="logedInForm" (ngSubmit) = "mdfLogin(logedInForm.value)" >
 //login UI
</
form>

Steps 3 - Initialize FormGroup and FormControl in ngOnInit method
  ngOnInit() {
    this.date = new Date(); // Today date and time
    this.logedInForm = new FormGroup({
      emailId: new FormControl("[email protected]", Validators.compose([
          Validators.required,
          Validators.pattern("[^ @]*@[^ @]*")
     ])),
      password: new FormControl('Password!123', [
           Validators.minLength(8),
           Validators.required])
    })
  }


Steps 4 – Create login method to preform login actions
  // Model Driven Form - login
  mdfLogin(data) {
    this.emailId = data.emailId;
    this.password = data.password;
    alert(JSON.stringify(data));
  }


And
<form [formGroup]="logedInForm" (ngSubmit) = "mdfLogin(logedInForm.value)" >
        <div>
            <input type="text" class="textbox" name="emailId" placeholder="Email" formControlName="emailId">
        </div>      
        <div>
            <input type="password" class="textbox" name="password" placeholder="password" formControlName="password">
        </div>
        <div>
            <input type="submit" class="button default-button" value="LogIn" [disabled] = "!logedInForm.valid">
        </div>
    </form>
