这篇文章主要介绍了yii2分页之实现跳转到具体某页的实例代码的相关资料,需要的朋友可以参考下
先上图看效果,大家感觉还错请参考功能怎么实现的!
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,具体直接参考狼蚁网站SEO优化完整版代码,可主要看go部分的代码实现。
<?php namespace frontend\components; use yii\widgets\LinkPager; use yii\helpers\Html; class GoLinkPager extends LinkPager { // 是否包含跳转功能跳转 默认false public $go = false; protected function renderPageButtons() { $pageCount = $this->pagination->getPageCount(); if ($pageCount < 2 && $this->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, $currentPage <= 0, false); } // prev page if ($this->prevPageLabel !== false) { if (($page = $currentPage - 1) < 0) { $page = 0; } $buttons[] = $this->renderPageButton($this->prevPageLabel, $page, $this->prevPageCssClass, $currentPage <= 0, false); } // internal pages list($beginPage, $endPage) = $this->getPageRange(); for ($i = $beginPage; $i <= $endPage; ++$i) { $buttons[] = $this->renderPageButton($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; $goHtml = <<<goHtml <div class="form" style="float: left; color: #999; margin-left: 10px; font-size: 12px;"> <span class="text">共 {$pageCount} 页</span> <span class="text">到第</span> <input class="input" type="number" value="{$goPage}" min="1" max="{$pageCount}" aria-label="页码输入框" style="text-align: center; height: 25px; line-height: 20px; margin-top: 5px; width: 46px;"> <span class="text">页</span> <span class="btn go-page" role="button" tabindex="0" style="border: solid 1px #ccc; padding: 0px; height: 25px; width: 46px; line-height: 25px;">确定</span> </div> goHtml; $buttons[] = $goHtml; $pageLink = $this->pagination->createUrl(false); $goJs = <<<goJs $(".go-page").on("click", function () { var _this = $(this), _pageInput = _this.siblings("input"), goPage = _pageInput.val(), pageLink = "{$pageLink}"; pageLink = pageLink.replace("page=1", "page="+goPage); if (goPage >= 1 && goPage <= {$pageCount}) { window.location.href=pageLink; } else { _pageInput.focus(); } }); goJs; $this->view->registerJs($goJs); } return Html::tag('ul', implode("\n", $buttons), $this->options); } }
狼蚁网站SEO优化看具体使用:
<?= GoLinkPager::widget([ 'pagination' => $pages, 'go' => true, ]); ?>
可以看出,使用起来也是贼方便贼方便的!加一个属性go为true即可。
需要说明的是,完整版代码中go部分html js可根据自己需要自行修改整理!
