1、简介
Pjax 是一个 jQuery 插件,其作用是使用 ajax 来加速页面加载时间,工作原理是只从服务器获取指定 HTML 片段,然后客户端使用获取到的内容更新局部页面。
Laravel Pjax 扩展包将 Pjax 集成到 Laravel 中,实现原理是提供一个中间件,返回 Pjax 期望的响应内容。
2、安装
通过 Composer 安装扩展包:
$ composer require spatie/laravel-pjax
接下来需要在 Kernel.php 中注册中间件,这里我们将其注册到web中间件组:
// app/Http/Kernel.phpprotected $middlewareGroups = [ 'web' => [ ... \Spatie\Pjax\Middleware\FilterIfPjax::class, ], ...];
3、使用
该扩展包提供的中间件会处理服务端返回的内容并将其转化为 Pjax 插件期望服务端返回的内容。
这里我们以 php artisan make:auth 命令生成的默认视图文件为例演示其使用,首先我们修改路由文件 routes.php :
Route::group(['middleware' => 'web'], function () { Route::get('/', function () { return view('welcome'); }); Route::get('/home', 'HomeController@index'); Route::auth();});
然后我们还需要修改默认布局文件 layouts/app.blade.php ,添加 Pjax 设置:
...<div class="main-content" id="pjax-container"> @yield('content')</div><!-- JavaScripts --><script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/2.1.4/jquery.min.js"></script><script src="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.6/js/bootstrap.min.js"></script>{{-- <script src="{{ elixir('js/app.js') }}"></script> --}}<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery.pjax/1.9.6/jquery.pjax.min.js"></script><script> $(document).pjax('a', '#pjax-container'); $(document).on("pjax:timeout", function(event) { // 阻止超时导致链接跳转事件发生 event.preventDefault() });</script></body></html>
这样我们就可以在浏览器中访问进行测试了:
你会发现在切换登录/注册按钮时页面不会发生跳转而直接进行刷新。
注:该扩展包会设置一个 X-AJAX 请求头以区别 pjax 请求和普通的 XHR 请求。在这种情况下,如果请求是 pjax,我们会跳过页面布局部分 HTML,只渲染页面主体部分内容。
Laravel 缓存失效
我们使用 Laravel Elixir 来管理前端缓存失效,你可以使用这种方法来让 Pjax 的缓存失效 —— 只需要引入 elixir 方法作为 x-pjax-version meta 的 content 即可:
<meta http-equiv="x-pjax-version" content="{{ elixir('css/app.css') }}">
如果是多个文件的话这使用:
<meta http-equiv="x-pjax-version" content="{{ elixir('css/app.css') . elixir('css/app2.css') }}">
这样的话,如果前端缓存失效,那么 Pjax 的缓存随之自动失效。

What’s still popular is the ease of use, flexibility and a strong ecosystem. 1) Ease of use and simple syntax make it the first choice for beginners. 2) Closely integrated with web development, excellent interaction with HTTP requests and database. 3) The huge ecosystem provides a wealth of tools and libraries. 4) Active community and open source nature adapts them to new needs and technology trends.

PHP and Python are both high-level programming languages that are widely used in web development, data processing and automation tasks. 1.PHP is often used to build dynamic websites and content management systems, while Python is often used to build web frameworks and data science. 2.PHP uses echo to output content, Python uses print. 3. Both support object-oriented programming, but the syntax and keywords are different. 4. PHP supports weak type conversion, while Python is more stringent. 5. PHP performance optimization includes using OPcache and asynchronous programming, while Python uses cProfile and asynchronous programming.

PHP is mainly procedural programming, but also supports object-oriented programming (OOP); Python supports a variety of paradigms, including OOP, functional and procedural programming. PHP is suitable for web development, and Python is suitable for a variety of applications such as data analysis and machine learning.

PHP originated in 1994 and was developed by RasmusLerdorf. It was originally used to track website visitors and gradually evolved into a server-side scripting language and was widely used in web development. Python was developed by Guidovan Rossum in the late 1980s and was first released in 1991. It emphasizes code readability and simplicity, and is suitable for scientific computing, data analysis and other fields.

PHP is suitable for web development and rapid prototyping, and Python is suitable for data science and machine learning. 1.PHP is used for dynamic web development, with simple syntax and suitable for rapid development. 2. Python has concise syntax, is suitable for multiple fields, and has a strong library ecosystem.

PHP remains important in the modernization process because it supports a large number of websites and applications and adapts to development needs through frameworks. 1.PHP7 improves performance and introduces new features. 2. Modern frameworks such as Laravel, Symfony and CodeIgniter simplify development and improve code quality. 3. Performance optimization and best practices further improve application efficiency.

PHP type prompts to improve code quality and readability. 1) Scalar type tips: Since PHP7.0, basic data types are allowed to be specified in function parameters, such as int, float, etc. 2) Return type prompt: Ensure the consistency of the function return value type. 3) Union type prompt: Since PHP8.0, multiple types are allowed to be specified in function parameters or return values. 4) Nullable type prompt: Allows to include null values and handle functions that may return null values.
