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：
PHP;">
namespace frontend\components;
use yii\widgets\LinkPager;
use yii\helpers\Html;
class GoLinkPager extends LinkPager
{
}
3、添加属性public $go = false; //是否包含跳转功能跳转 默认false
4、重写父类linkPager的renderPageButtons方法，具体直接参考下面完整版代码，可主要看go部分的代码实现。
PHP;">
pagination->getPageCount();
if ($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,$this->firstPageCssClass,$currentPage <= 0,false);
}
// prev page
if ($this->prevPageLabel !== false) {
if (($page = $currentPage - 1) < 0) {
$page = 0;
}
$buttons[] = $this->renderPageButton($this->prevPageLabel,$page,$this->prevPageCssClass,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,$this->nextPageCssClass,$currentPage >= $pageCount - 1,false);
}
// last page
$lastPageLabel = $this->lastPageLabel === true ? $pageCount : $this->lastPageLabel;
if ($lastPageLabel !== false) {
$buttons[] = $this->renderPageButton($lastPageLabel,$pageCount - 1,$this->lastPageCssClass,false);
}
// go
if ($this->go) {
$goPage = $currentPage + 2;
$goHtml = <<
页码输入框" style="text-align: center; height: 25px; line-height: 20px; margin-top: 5px; width: 46px;">
goHtml;
$buttons[] = $goHtml;
$pageLink = $this->pagination->createUrl(false);
$goJs = <<
