tp5基于layui版自定义跳转分页-php开发

当页数比较多的时候为了体高用户体验度，需要添加一个跳页也就是手动输入页码数进行快速跳转指定页面。由于手动编写分页比较麻烦，又想使用TP5自带的分页，但是TP5自带的分页类比较简单，所以可以通过修改Bootstrap

当页数比较多的时候为了体高用户体验度，需要添加一个跳页也就是手动输入页码数进行快速跳转指定页面。由于手动编写分页比较麻烦，又想使用TP5自带的分页，但是TP5自带的分页类比较简单，所以可以通过修改Bootstrap类自定义显示分页的页码和数量。

效果展示：

分页文件代码：Bootstrap_cusom.php

由于Bootstrap类是tp自带的类，所以为了我们尽量不要改动底层自带的类，这里拷贝一下Bootstrap类然后重命名为Bootstrap_cusom.php，目录结构如图：

config.php分页配置：

    // 分页配置
    'paginate'               => [
        'type'      => 'Bootstrap_cusom',
        'var_page'  => 'page',
        'first_page'=>true,//首页
        'last_page'=>true//尾页
    ],

也可以在调用分页方法的时候传入，例如：

$list = Db::name('user')->where('status',1)->paginate(10,true,[
    'type'     => 'Bootstrap_cusom',
    'var_page' => 'page',
]);
