        }else{//没分页显示初始
            $params = "<input class='layui-input' type='number' min='1' name='page'  value='' style='display:inline-block;width:60%;' placeholder='请输入页数'>";
        }

    }

}

把config.php分页配置中的bootstrap改成BootstrapPage

    //分页配置
    'paginate' => [
        'type'      =>  'BootstrapPage',///'bootstrap',
        'var_page'  => 'page',
        'list_rows' => 15,
    ],

然后后台全局使用paginate分页的地方都会改变。分页带参数搜索跳转和输入页码跳转都可以！
