> TP6.0 默認提供的分頁代碼中css樣式類名是Bootstrap3中的，如果項目中使用的是Bootstrap4，則不能正確展示分頁樣式效果，需要修改分頁驅(qū)動，使其樣式正確顯示 #### 1. TP6.0 默認分頁 --- **默認分頁驅(qū)動類文件** ``` vendor/topthink/think-orm/src/paginator/driver/Bootstrap.php ``` **默認分頁代碼** ```html <ul class="pagination"> <li><a href="?page=1">«</a></li> <li><a href="?page=1">1</a></li> <li class="active"><span>2</span></li> <li class="disabled"><span>»</span></li> </ul> ``` #### 2. 修改默認分頁驅(qū)動 --- **a. 復(fù)制默認分頁驅(qū)動類** ``` vendor/topthink/think-orm/src/paginator/driver/Bootstrap.php ``` **b. 粘貼到 `app/driver` 目錄下，重命名為 MyPage、修改命名空間** ``` app/driver/MyPage.php ``` **c. 修改文件 `app/provider.php`，添加以下內(nèi)容** ``` // 修改默認分頁驅(qū)動 'think\Paginator' => app\driver\MyPage::class, ``` **d. 修改自定義分頁驅(qū)動文件 `app/driver/MyPage.php`** 給 li 添加 .page-item，給 a 標(biāo)簽 和 span 標(biāo)簽添加 .page-link **e. 修改前和修改后的對比**   **f. 修改后的分頁驅(qū)動，在 Bootstrap4.x 中可直接使用** ```php <?php namespace app\driver; use think\Paginator; /** * Bootstrap 分頁驅(qū)動 */ class MyPage extends Paginator { /** * 上一頁按鈕 * @param string $text * @return string */ protected function getPreviousButton(string $text = "«"): string { if ($this->currentPage() <= 1) { return $this->getDisabledTextWrapper($text); } $url = $this->url( $this->currentPage() - 1 ); return $this->getPageLinkWrapper($url, $text); } /** * 下一頁按鈕 * @param string $text * @return string */ protected function getNextButton(string $text = '»'): string { if (!$this->hasMore) { return $this->getDisabledTextWrapper($text); } $url = $this->url($this->currentPage() + 1); return $this->getPageLinkWrapper($url, $text); } /** * 頁碼按鈕 * @return string */ protected function getLinks(): string { if ($this->simple) { return ''; } $block = [ 'first' => null, 'slider' => null, 'last' => null, ]; $side = 3; $window = $side * 2; if ($this->lastPage < $window + 6) { $block['first'] = $this->getUrlRange(1, $this->lastPage); } elseif ($this->currentPage <= $window) { $block['first'] = $this->getUrlRange(1, $window + 2); $block['last'] = $this->getUrlRange($this->lastPage - 1, $this->lastPage); } elseif ($this->currentPage > ($this->lastPage - $window)) { $block['first'] = $this->getUrlRange(1, 2); $block['last'] = $this->getUrlRange($this->lastPage - ($window + 2), $this->lastPage); } else { $block['first'] = $this->getUrlRange(1, 2); $block['slider'] = $this->getUrlRange($this->currentPage - $side, $this->currentPage + $side); $block['last'] = $this->getUrlRange($this->lastPage - 1, $this->lastPage); } $html = ''; if (is_array($block['first'])) { $html .= $this->getUrlLinks($block['first']); } if (is_array($block['slider'])) { $html .= $this->getDots(); $html .= $this->getUrlLinks($block['slider']); } if (is_array($block['last'])) { $html .= $this->getDots(); $html .= $this->getUrlLinks($block['last']); } return $html; } /** * 渲染分頁html * @return mixed */ public function render() { if ($this->hasPages()) { if ($this->simple) { return sprintf( '<ul class="pager">%s %s</ul>', $this->getPreviousButton(), $this->getNextButton() ); } else { return sprintf( '<ul class="pagination">%s %s %s</ul>', $this->getPreviousButton(), $this->getLinks(), $this->getNextButton() ); } } } /** * 生成一個可點擊的按鈕 * * @param string $url * @param string $page * @return string */ protected function getAvailablePageWrapper(string $url, string $page): string { return '<li class="page-item"><a href="' . htmlentities($url) .
