yii2分页跳转到指定页

Posted 2020-08-29 木子炜培先生

先上图看效果，样式虽然有点丑，这都不重要，我相信拿到代码的你们更注重的是这功能怎么实现的！

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
        $(document).on(\'click\', \'.go-page\', 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！
