laravel框架学习之路(二)pjax的使用


继第一篇文章发布之后laravel框架学习之路(一)前后台用户认证分离,忙着项目上的事情,一直没有时间写文章。进入到新公司后,忙里偷闲,继续我的laravel框架学习之路。如需参考代码请移步kaihongChan@github.com(ps:项目还在逐步完善中,还有许多不足,如遇bug,请在评论区告知笔者)

关于什么是pjax,请读者自行百度。

准备工作:
1、下载jquery.pjax.js文件点击下载
2、下载NProgress
3、将所需文件放入项目中,并在布局文件中引用。(框架public目录下)

开始:
这里笔者使用的是adminLTE后台模板,具体使用可参考在Laravel5.* 中使用 AdminLTE

安装pjax的composer包(laravel中间件):

$ composer require spatie/laravel-pjax

在kernel.php文件中加入代码:

// app/Http/Kernel.php

...

protected $middleware = [

...

/Spatie/Pjax/Middleware/FilterIfPjax::class,

];

配置pjax完成页面交互:(ps:笔者整站使用pjax加载页面,故在全局js文件中配置pjax,读者可根据需要另行配置)

$.pjax.defaults.timeout = 5000;
$.pjax.defaults.maxCacheLength = 0;
//配置可点击的<a>标签使用pjax
$(document).pjax('a:not(a[target="_blank"])', {
    container: '#pjax-container'//配置pjax刷新容器
});

NProgress.configure({parent: '#pjax-container'});
//超时执行函数
$(document).on('pjax:timeout', function (event) {
    event.preventDefault();
});

至此,laravel结合pjax已完成。
