先上图看效果,大家感觉还错请参考功能怎么实现的!
goHtml;
$buttons[] = $goHtml;
$pageLink = $this->pagination->createUrl(false);
$goJs = = 1 && goPage view->registerJs($goJs);
}
return Html::tag('ul', implode("\n", $buttons), $this->options);
}
}
从上图中不难看出,我们制定跳转到某页的功能是基于linkpager之上的扩展,这根我们之前实现的分页扩展明显不同,之前的明显就是重写了!当然,这都不重要,我们看看GoLinkPager的具体实现!名字起的有点lower,不重要!
1、在frontend\components目录新建GoLinkPager类文件
2、该类继承yii\widgets\LinkPager;,如下:
namespace frontend\components; use yii\widgets\LinkPager; use yii\helpers\Html; class GoLinkPager extends LinkPager { }
3、添加属性public $go = false; //是否包含跳转功能跳转 默认false
4、重写父类linkPager的renderPageButtons方法,具体直接参考下面完整版代码,可主要看go部分的代码实现。
pagination->getPageCount(); if ($pageCount hideOnSinglePage) { return ''; } $buttons = []; $currentPage = $this->pagination->getPage(); // first page $firstPageLabel = $this->firstPageLabel === true ? '1' : $this->firstPageLabel; if ($firstPageLabel !== false) { $buttons[] = $this->renderPageButton($firstPageLabel, 0, $this->firstPageCssClass, $currentPage prevPageLabel !== false) { if (($page = $currentPage - 1) renderPageButton($this->prevPageLabel, $page, $this->prevPageCssClass, $currentPage getPageRange(); for ($i = $beginPage; $i renderPageButton($i + 1, $i, null, false, $i == $currentPage); } // next page if ($this->nextPageLabel !== false) { if (($page = $currentPage + 1) >= $pageCount - 1) { $page = $pageCount - 1; } $buttons[] = $this->renderPageButton($this->nextPageLabel, $page, $this->nextPageCssClass, $currentPage >= $pageCount - 1, false); } // last page $lastPageLabel = $this->lastPageLabel === true ? $pageCount : $this->lastPageLabel; if ($lastPageLabel !== false) { $buttons[] = $this->renderPageButton($lastPageLabel, $pageCount - 1, $this->lastPageCssClass, $currentPage >= $pageCount - 1, false); } // go if ($this->go) { $goPage = $currentPage + 2; $goHtml = 共 {$pageCount} 页 到第 页 确定
