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。
<?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);
}
}
下面看具体使用:
<?= 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!
