Yii2实现增删改查后留在当前页的方法详解

前言

实现增删改查操作成功后仍留在当前页，能给用户一个良好的体验。但是 Yii2 框架本身是没有在增删改查操作成功后仍留在当前页的效果的，要实现这样的一个效果得自己写。我的原则是不动核心代码，始终坚持自己的原则，现实现了我把它分享出来。殊途同归，如有更好的实现方法，欢迎交流。

一、实现增删改查后操作成功后仍然留在当前页面。

1、链接的效果图

封装代码

共有两个文件ActionColumn.PHP和Helper.PHP1、ActionColumn.PHP文件

use kartik\icons\Icon;
use Yii;
use yii\grid\Column;
use yii\helpers\ArrayHelper;
use yii\helpers\Html;
