Bagaimana cara mengaktifkan AJAX untuk tombol 'Tambah ke Troli' dari widget produk di Magento 2?

Di Magento 2 Add to Carttombol normal memiliki logika berbasis AJAX yang sangat bagus untuk menambahkan produk ke keranjang.
Namun, ketika kita menggunakan Catalog Products Listwidget misalnya di halaman CMS tombol di daftar produk ini berfungsi dengan HTTP POSTyang memuat ulang halaman saat ini.

Pengalaman pengguna menderita dari ini dan itu akan diinginkan jika tombol akan memiliki logika AJAX yang sama seperti dalam daftar produk kategori default atau pada halaman produk.

Bagaimana kita bisa memperluas Catalog Products Listwidget sehingga menggunakan tombol yang lebih baik Add to Cart ? Atau mungkin ada solusi lain?

Anda harus mengganti file addtocart.phtml

app/design/frontend/vendorname/themename/Magento_Catalog/templates/product/view/addtocart.phtml

Sekarang, Ganti "bindSubmit": false dengan "bindSubmit": true

<script type="text/x-magento-init">
    {
        "#product_addtocart_form": {
            "catalogAddToCart": {
                "bindSubmit": false
            }
        }
    }
</script>

Untuk

<script type="text/x-magento-init">
    {
        "#product_addtocart_form": {
            "catalogAddToCart": {
                "bindSubmit": true
            }
        }
    }
</script>

Sekarang hapus cache dan folder page_cache atau cache flush.

Catatan: Pastikan Anda harus mengatur TIDAK dari Store->Configuration->Sales->Checkout->Shopping Cart->After Adding a Product Redirect to Shopping Cart to No

Anda dapat memperluas Catalog Products Listuntuk menggunakan gerobak ajax dengan membuat modul dengan file-file berikut:

/Your/Module/Block/Product/ListBlock.php dengan konten:

<?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\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),
            ]

Di Magento 2.2, Magento_Catalog/product/view/validationskrip disebut bukan catalogAddToCart.

Ini sudah ada di addtocart.phtml(dengan radioCheckboxClosestopsi konfigurasi), jadi untuk mengaktifkan Ajax Add to Cart cukup tambahkan bindSubmitopsi seperti:

<script type="text/x-magento-init">
{
    "#product_addtocart_form": {
        "Magento_Catalog/product/view/validation": {
            "bindSubmit": true,
            "radioCheckboxClosest": ".nested"
        }
    }
}
</script>

Dalam rilis Magento 2 terbaru ini telah diubah lagi dan sekarang

<script type="text/x-magento-init">
