您可以Catalog Products List通过创建包含以下文件的模块，将扩展为使用ajax购物车：
/Your/Module/Block/Product/ListBlock.php内容：
<?php
namespace Your\Module\Block\Product;
use Magento\CatalogWidget\Block\Product\ProductsList;
class ListBlock extends ProductsList
{
/**
* @var \Magento\Framework\Url\Helper\Data
*/
protected $urlHelper;
public function __construct(
\Magento\Catalog\Block\Product\Context $context,
\Magento\Catalog\Model\ResourceModel\Product\CollectionFactory $productCollectionFactory,
\Magento\Catalog\Model\Product\Visibility $catalogProductVisibility,
\Magento\Framework\App\Http\Context $httpContext,
\Magento\Rule\Model\Condition\Sql\Builder $sqlBuilder,
\Magento\CatalogWidget\Model\Rule $rule,
\Magento\Widget\Helper\Conditions $conditionsHelper,
\Magento\Framework\Url\Helper\Data $urlHelper,
array $data
)
{
$this->urlHelper = $urlHelper;
parent::__construct($context, $productCollectionFactory, $catalogProductVisibility, $httpContext, $sqlBuilder, $rule, $conditionsHelper, $data);
}
/**
* Get post parameters
*
* @param \Magento\Catalog\Model\Product $product
* @return string
*/
public function getAddToCartPostParams(\Magento\Catalog\Model\Product $product)
{
$url = $this->getAddToCartUrl($product);
return [
'action' => $url,
'data' => [
'product' => $product->getEntityId(),
\Magento\Framework\App\ActionInterface::PARAM_NAME_URL_ENCODED =>
$this->urlHelper->getEncodedUrl($url),
]
];
}
}
