Angular15 came and if you are new then you must check below link:

  1. Angular 15 Tutorials

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">
            
                    <div class="col-12 mb-4">
                        <h4>Flight Booking</h4>
                        <span class="text-muted">Please make the payment to start enjoying all the features of our premium plan as soon as possible</span>
                    </div>
                    <div class="col-12">
                        <div class="form-check form-check-inline mb-3">

                            <label class="form-check-label" for="Roundtrip">Roundtrip</label>
                            <div *ngIf="submitted && f.roundtripopt.errors" class="invalid-feedback mb" style="display: table;position: absolute;left: 16px;top: 150px;margin-bottom: 5px;">
                                <div *ngIf="f.roundtripopt.errors.required">Roundtrip is required.</div>
                             </div>
                        </div>
                        <div class="form-check form-check-inline">
                            <input class="form-check-input" type="radio" name="inlineRadioOptions" id="Oneway" value="option2" formControlName="roundtripopt"  [ngClass]="{ 'is-invalid': submitted && f.roundtripopt.errors }">

                        <div class="form-check form-check-inline">
                            <input class="form-check-input" type="radio" name="inlineRadioOptions" id="MultiCity" value="option3" formControlName="roundtripopt"  [ngClass]="{ 'is-invalid': submitted && f.roundtripopt.errors }">

                    <div class="col-12 mt-4">
                        <button class="btn btn-primary text-uppercase" type="submit">SHOWN FLIGHTS<i class="fa fa-plane ms-3"></i></button>
                    </div>
                
            </div>
        </form>
    </div>
</div>

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.

Jassa
