yii2分页之实现跳转到具体某页的实例代码

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，具体直接参考下面完整版代码，可主要看go部分的代码实现。

<?phpnamespace 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); }}
