在ajax yii2上处理面包块

<div class="breadcrumb-container">
    <ul class="breadcrumb">
        <li><a href="/">首页</a></li>
        <li class="active">当前页面</li>
    </ul>
</div>

public function actionUpdateBreadcrumb($pageId)
{
    // 根据页面ID获取页面信息
    $page = Page::findOne($pageId);

    // 生成面包块导航HTML
    $breadcrumbHtml = $this->renderPartial('_breadcrumb', ['page' => $page]);

    // 返回更新后的面包块导航HTML
    return Json::encode(['breadcrumbHtml' => $breadcrumbHtml]);
}

<?php
use yii\helpers\Html;

// 递归生成面包块导航
function renderBreadcrumb($page)
{
    if ($page->parent) {
        renderBreadcrumb($page->parent);
    }
    echo '<li>' . Html::a($page->title, ['page/view', 'id' => $page->id]) . '</li>';
}

// 渲染面包块导航
echo '<ul class="breadcrumb">';
echo '<li>' . Html::a('首页', '/') . '</li>';
renderBreadcrumb($page);
echo '<li class="active">' . $page->title . '</li>';
echo '</ul>';
?>

$.ajax({
    url: '/site/update-breadcrumb',
    type: 'GET',
    data: {pageId: 123}, // 替换为当前页面的ID
    success: function(response) {
        // 更新面包块导航
        $('.breadcrumb-container').html(response.breadcrumbHtml);
    }
});
