Hello friends, welcome back to my blog. Today this blog post will tell you, Angular 12 Modal Popup Forms Tutorial.
Angular12 came and Bootstrap 5 also. If you are new then you must check below two links:
Friends now I proceed onwards and here is the working code snippet and please use carefully this to avoid the mistakes:
1. Firstly friends we need fresh angular 12 setup and for this we need to run below commands but if you already have angular 12 setup then you can avoid below commands. Secondly we should also have latest node version installed on our system:
npm install -g @angular/cli ng new angularboot5 //Create new Angular Project cd angularboot5 // Go inside the Angular Project Folder
2. Now friends we need to run below commands into our project terminal to install bootstrap 5 modules into our angular application:
npm install bootstrap npm i @popperjs/core
3. Now friends we just need to add below code into angularboot5/src/app/app.component.html file to get final out on the web browser:
<button type="button" class="btn btn-primary me-5" data-bs-toggle="modal" data-bs-target="#exampleModal">
User Login
</button>
<button type="button" class="btn btn-primary" data-bs-toggle="modal" data-bs-target="#exampleModal2">
Validation Form
</button>
<!-- Modal -->
<div class="modal fade" id="exampleModal" tabindex="-1" aria-labelledby="exampleModalLabel" aria-hidden="true">
<div class="modal-dialog">
<div class="modal-content">
<div class="modal-header">
<h5 class="modal-title text-danger" id="exampleModalLabel">Login Form</h5>
<button type="button" class="btn-close" data-bs-dismiss="modal" aria-label="Close"></button>
</div>
<div class="modal-body">
<form>
<div class="mb-3">
<label for="exampleInputEmail1" class="form-label">Email address</label>
<input type="email" class="form-control" id="exampleInputEmail1" aria-describedby="emailHelp">
<div id="emailHelp" class="form-text">We'll never share your email with anyone else.</div>
</div>
<div class="mb-3">
<label for="exampleInputPassword1" class="form-label">Password</label>
<input type="password" class="form-control" id="exampleInputPassword1">
</div>
<button type="button" class="btn btn-primary">Login</button>
</form>
</div>
<div class="modal-footer">
<button type="button" class="btn btn-warning" data-bs-dismiss="modal">Close</button>
</div>
</div>
</div>
</div>
<!-- Modal 2 with validation-->
<div class="modal fade" id="exampleModal2" tabindex="-1" aria-labelledby="exampleModal2Label" aria-hidden="true">
<div class="modal-dialog">
<div class="modal-content">
<div class="modal-header">
<h5 class="modal-title text-danger" id="exampleModal2Label">Login Form</h5>
<button type="button" class="btn-close" data-bs-dismiss="modal" aria-label="Close"></button>
</div>
<div class="modal-body">
<form [formGroup]="registerForm" (ngSubmit)="onSubmit()">
<div class="mb-3">
<label for="exampleInputEmail1" class="form-label">Email address</label>
<input type="email" formControlName="email" class="form-control" [ngClass]="{ 'is-invalid': submitted && f.email.errors }" id="inputEmail4">
<div *ngIf="submitted && f.email.errors" class="invalid-feedback">
<div *ngIf="f.email.errors.required">Email is required</div>
<div *ngIf="f.email.errors.email">Email must be a valid email address</div>
</div>
</div>
<div class="mb-3">
<label for="exampleInputPassword1" class="form-label">Password</label>
<input type="password" formControlName="password" class="form-control" [ngClass]="{ 'is-invalid': submitted && f.password.errors }" id="inputPassword4">
<div *ngIf="submitted && f.password.errors" class="invalid-feedback">
<div *ngIf="f.password.errors.required">Password is required</div>
</div>
</div>
<button type="submit" class="btn btn-primary">Login</button>
</form>
</div>
<div class="modal-footer">
<button type="button" class="btn btn-warning" data-bs-dismiss="modal">Close</button>
</div>
</div>
</div>
</div>
4. Now friends we just need to add below code into angularboot5/angular.json file:
"styles": [
...
"node_modules/bootstrap/dist/css/bootstrap.min.css"
],
"scripts": [
...
"node_modules/bootstrap/dist/js/bootstrap.min.js"
]
5. Now friends we just need to add below code into angularboot5/src/app/app.module.ts file for reactive forms:
...
import { ReactiveFormsModule } from '@angular/forms';
@NgModule({
...
imports: [
...
ReactiveFormsModule,
],
6. Now friends we just need to add below code into angularboot5/src/app/app.component.ts file to validation and other reactive form functions:
...
import { FormBuilder, FormGroup, Validators } from '@angular/forms';
export class AppComponent {
//Form Validables
registerForm: FormGroup;
submitted = false;
constructor( private formBuilder: FormBuilder){}
//Add user form actions
get f() { return this.registerForm.controls; }
onSubmit() {
this.submitted = true;
// stop here if form is invalid
if (this.registerForm.invalid) {
return;
}
//True if all the fields are filled
if(this.submitted)
{
alert("Great!!");
}
}
ngOnInit() {
//Add User form validations
this.registerForm = this.formBuilder.group({
email: ['', [Validators.required, Validators.email]],
password: ['', [Validators.required]],
});
}
}
Friends in the end must run ng serve command into your terminal to run the angular 12 project(localhost:4200).
Now we are done friends. If you have any kind of query, suggestion and new requirement then feel free to comment below.
