Laravel implements Ajax paging

With the development of the Internet and the advancement of technology, modern web applications have increasingly higher requirements for user experience. In such applications, paging is an indispensable feature. In the traditional paging method, the traditional page refresh method is used for page jumps and data loading, which will lead to a reduction in user experience. Especially when the amount of data is huge, users need to wait for a long time to see the desired content. Therefore, a new paging method is widely used - Ajax paging.

The Laravel framework provides powerful support and allows us to easily implement Ajax paging. This article will introduce how to use Laravel to implement Ajax paging.

1. Configure routing

First, we need to configure routing to support Ajax paging. Add the following route in the web.php file:

Route::get('/posts',?'PostController@index');
Route::get('/posts/fetch_data',?'PostController@fetch_data');

2. Create Controller

Next, we need to create a controller to handle the request. Run the following command to create a PostController in Laravel:

php?artisan?make:controller?PostController

Add the following code in the PostController:

<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;
use App\Post;

class PostController extends Controller
{
    public function index()
    {
        $posts = Post::paginate(5);
        return view(&#39;posts.index&#39;, compact(&#39;posts&#39;));
    }

    public function fetch_data(Request $request)
    {
        if($request->ajax())?{
????????????$posts?=?Post::paginate(5);
????????????return?view('posts.data',?compact('posts'))->render();
????????}
????}

}

We use the paginate method to get the post data. In the fetch_data method, we use a blade view named data to render the data as shown below:

<div class="row">
????@foreach($posts?as?$post)
????????<div class="col-md-6">
????????????<div class="card mb-3">
????????????????<img class="card-img-top" src="{{ $post->image?}}"?alt="{{?$post->title?}}">
????????????????<div class="card-body">
????????????????????<h5 class="card-title">{{?$post->title?}}</h5>
????????????????????<p class="card-text">{{?$post->excerpt?}}</p>
????????????????????<a href="{{ route(&#39;posts.show&#39;, $post) }}" class="btn btn-primary">Read?More</a>
????????????????</div>
????????????</div>
????????</div>
????@endforeach
</div>

3. Create View

Now, we need to create a view to display post data and enable Ajax pagination. Add the following content in the resources/views/posts/index.blade.php file:

@extends('layouts.app')

@section('content')
????<div class="container">
????????<div id="posts">
????????????@include('posts.data')
????????</div>
????????<div class="d-flex justify-content-center">
????????????{{?$posts->links()?}}
????????</div>
????</div>
@endsection

@section('scripts')
????<script>
????????$(document).ready(function()?{
????????????$(document).on('click',?'.pagination?a',?function(e)?{
????????????????e.preventDefault();

????????????????var?page?=?$(this).attr('href').split('page=')[1];
????????????????fetch_data(page);
????????????});
????????});

????????function?fetch_data(page)
????????{
????????????$.ajax({
????????????????url:"/posts/fetch_data?page="+page,
????????????????success:function(data)
????????????????{
????????????????????$('#posts').html(data);
????????????????}
????????????});
????????}
????</script>
@endsection

Here, we use blade’s @pagination directive to render the page number link, and include the data. In the @scripts directive, we use jQuery to handle the click event and render the data.

4. Create styles

Finally, we need to add some styles to make the page look prettier. Add the following code to the public/css/app.css file:

.card?{
????border:?none;
}

.card-text?{
????color:?#555;
}

.card-img-top?{
????height:?220px;
????object-fit:?cover;
}

Now our Laravel application is ready to use Ajax pagination! When the user clicks on the page number link, the page will load the data without refreshing. This can greatly improve the user experience, especially when the amount of data is particularly large.
