<?php
  
namespace App\Http\Livewire;
  
use Livewire\Component;
   
class ChangeEvent extends Component
{
    public $cities = [
        1 => 'Rajkot',
        2 => 'Surat',
        3 => 'Vadodara'
    ];

        return view('livewire.change-event')->extends('layouts.app');
    }
  
    /**

     * @return response()
     */
    public function changeEvent($value)
    {
        $this->city_id = $value;
    }
}

resources/views/livewire/change-event.blade.php

<div>
    <h1>Laravel Livewire Change Event Example - ItSolutionStuff.com</h1>
    <div>
        <strong>Select City:</strong>
        <select class="form-control" wire:click="changeEvent($event.target.value)">
            <option value="">-- Select City --</option>
            @foreach($cities as $key => $city)
                <option value="{{ $key }}">{{ $city }}</option>
            @endforeach
        </select>
  
        <p>Selected City ID: {{ $city_id }}</p>
    </div>
</div>

Step 4: Create Route

now we will create one route for calling our example, so let’s add new route to web.php file as bellow:

routes/web.php

<?php
  
use Illuminate\Support\Facades\Route;
 
use App\Http\Livewire\ChangeEvent;
  
/*
|--------------------------------------------------------------------------
| Web Routes
|--------------------------------------------------------------------------
|
| Here is where you can register web routes for your application. These
| routes are loaded by the RouteServiceProvider within a group which
| contains the "web" middleware group. Now create something great!
|
*/
  
Route::get('change-event', ChangeEvent::class);

Step 5: Create View File

here, we will create blade file for call form route. in this file we will use @livewireStyles, @livewireScripts. so let’s add it.

resources/views/layouts/app.blade.php

<!DOCTYPE html>
<html>
<head>
    <title>Laravel Livewire Example - ItSolutionStuff.com</title>
    @livewireStyles
    <script src="//cdnjs.cloudflare.com/ajax/libs/jquery/3.2.1/jquery.min.js"></script>
    <link href="//maxcdn.bootstrapcdn.com/bootstrap/4.1.1/css/bootstrap.min.css" rel="stylesheet" id="bootstrap-css">
    <script src="//maxcdn.bootstrapcdn.com/bootstrap/4.1.1/js/bootstrap.min.js"></script>
</head>
<body>
    
<div class="container">
    @yield('content')
</div>
    
</body>
  
@livewireScripts
</html>

Now you can run using bellow command:
