繼第一篇文章釋出之後laravel框架學習之路（一）前後臺使用者認證分離，忙著專案上的事情，一直沒有時間寫文章。進入到新公司後，忙裡偷閒，繼續我的laravel框架學習之路。如需參考程式碼請移步kaihongChan@github.com（ps:專案還在逐步完善中，還有許多不足，如遇bug，請在評論區告知筆者）

關於什麼是pjax，請讀者自行百度。

準備工作：
1、下載jquery.pjax.js檔案點選下載
2、下載NProgress
3、將所需檔案放入專案中，並在佈局檔案中引用。（框架public目錄下）

開始：
這裡筆者使用的是adminLTE後臺模板，具體使用可參考在Laravel5.* 中使用 AdminLTE

安裝pjax的composer包（laravel中介軟體）：

$ composer require spatie/laravel-pjax

在kernel.php檔案中加入程式碼:

// app/Http/Kernel.php

...

protected $middleware = [

...

SpatiePjaxMiddlewareFilterIfPjax::class,

];

配置pjax完成頁面互動：（ps：筆者整站使用pjax載入頁面，故在全域性js檔案中配置pjax，讀者可根據需要另行配置）

$.pjax.defaults.timeout = 5000;
$.pjax.defaults.maxCacheLength = 0;
//配置可點選的<a>標籤使用pjax
$(document).pjax(`a:not(a[target="_blank"])`, {
    container: `#pjax-container`//配置pjax重新整理容器
});

NProgress.configure({parent: `#pjax-container`});
//超時執行函式
$(document).on(`pjax:timeout`, function (event) {
    event.preventDefault();
});

至此，laravel結合pjax已完成。
