Hello to all, welcome to therichpost.com. In this post, I will tell you, Angular 15 Flight Booking Form with Validations Working Example.
Guys with this we will cover below things:
- Angular 15 Reactive Form Implelemtnation.
- Reactive forms validation email with valid format.
- Reactive form checkbox validation.
- Angular15 Reactive Form Responsiveness with Bootstrap 5.
Angular15 came and if you are new then you must check below link:
Here is the code snippet and please use carefully:
1. Very first guys, here are common basics steps to add angular 15 application on your machine and also we must have latest nodejs version(14.17.0) installed for angular 15:
npm install -g @angular/cli ng new angularform // Set Angular 15 Application on your pc cd angularform // Go inside project folder
2. Now run below commands to set bootstrap 5 modules into our angular 15 application for responsiveness (optional):
npm install bootstrap npm i @popperjs/core
3. Now friends we just need to add below code into angularform/angular.json file (optional):
"styles": [
...
"node_modules/bootstrap/dist/css/bootstrap.min.css"
],
"scripts": [
...
"node_modules/bootstrap/dist/js/bootstrap.min.js"
]
4. Now guys we will add below code into our angularform/src/app/app.module.ts file:
...
import { ReactiveFormsModule } from '@angular/forms';
@NgModule({
...
imports: [
...
ReactiveFormsModule,
],
providers: [],
bootstrap: [AppComponent]
})
export class AppModule { }
5. Now guys we will add below code into our angularform/src/app/app.component.ts file:
import { Component } from '@angular/core';
import { FormControl,FormGroup,Validators,FormBuilder } from '@angular/forms';
@Component({
selector: 'app-root',
templateUrl: './app.component.html',
styleUrls: ['./app.component.css']
})
export class AppComponent {
//Form variables
registerForm:any = 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 form validations
this.registerForm = this.formBuilder.group({
ffrom: ['', [Validators.required]],
fto: ['', [Validators.required]],
dparting: ['', [Validators.required]],
returning: ['', [Validators.required]],
adults: ['', [Validators.required]],
children: ['', [Validators.required]],
travel: ['', [Validators.required]],
roundtripopt: ['', [Validators.required]],
});
}
}
6. Finally we will add below code into our angularform/src/app/app.component.html file:
<div class="container">
<div class="card p-4 mt-5">
<form [formGroup]="registerForm" (ngSubmit)="onSubmit()">
<div class="row g-3">

7. Now we will add below font awesome icons link into our angularform/src/index.html file:
<!doctype html> <html lang="en"> <head> ... <link rel="stylesheet" href="https://cdnjs.cloudflare.com/ajax/libs/font-awesome/4.0.3/css/font-awesome.css"/> </head>
Now we are done friends and please run ng serve command to check the output in browser(locahost:4200) and if you have any kind of query then please do comment below.
Note: Friends, I just tell the basic setup and things, you can change the code according to your requirements. For better understanding please watch video above.
Guys I will appreciate that if you will tell your views for this post. Nothing matters if your views will be good or bad.
