如何向/从WooCommerce Data-ProductVariments对象传递/获取数据？

向/从data-product_variations 产品单页中的属性表单。在使用WooCommerce时，我正在与产品库图像和产品变体进行一些交互。

基本上，我需要能够在woocommerce_variation_has_changed 事件

我能够在连接到的同时传递并获取数据属性single_product_large_thumbnail_size 和woocommerce_single_product_image_thumbnail_html.

我有not 能够在woocommerce_variation_has_changed 事件我所理解的（？）那是woocommerce_variation_has_changed 触发器从data-product_variations 对象插入与产品变体相关的图像标记。

综上所述，如何将数据属性添加到data-product_variations 对象在woocommerce_variation_has_changed 事件

这是对象在data-product_variations 看起来像。基本上我需要通过data-attr 当woocommerce_variation_has_changed 踢进来。

data-product_variations="[{
    "variation_id": 373,
    "variation_is_visible": true,
    "variation_is_active": true,
    "is_purchasable": true,
    "display_price": 100,
    "display_regular_price": 100,
    "attributes": {
        "attribute_pa_chain-length": "80cm"
    },
    "image_src": "",
    "image_link": "",
    "image_title": "",
    "image_alt": "",
    "image_caption": "",
    "image_srcset": "",
    "image_sizes": "",
    "price_html": "<span class=\\"price\\"><span class=\\"woocommerce-Price-amount amount\\"><span class=\\"woocommerce-Price-currencySymbol\\">&pound;<\\/span>100.00<\\/span><\\/span>",
    "availability_html": "",
    "sku": "",
    "weight": " kg",
    "dimensions": "",
    "min_qty": 1,
    "max_qty": null,
    "backorders_allowed": false,
    "is_in_stock": true,
    "is_downloadable": false,
    "is_virtual": false,
    "is_sold_individually": "no",
    "variation_description": ""
}]"

jQuery(document).on(\'found_variation.wc-variation-form\', \'form.variations_form\', function(event, variation_data) { //this is called when a valid productis found }); jQuery(document).on(\'change.wc-variation-form\', \'form.variations_form\', function(event) { //this function is called when the user clicks or changes the dropdown });

apply_filters( \'woocommerce_available_variation\', array( \'attributes\' => $variation->get_variation_attributes(), \'availability_html\' => wc_get_stock_html( $variation ), \'backorders_allowed\' => $variation->backorders_allowed(), \'dimensions\' => $variation->get_dimensions( false ), \'dimensions_html\' => wc_format_dimensions( $variation->get_dimensions( false ) ), \'display_price\' => wc_get_price_to_display( $variation ), \'display_regular_price\' => wc_get_price_to_display( $variation, array( \'price\' => $variation->get_regular_price() ) ), \'image\' => wc_get_product_attachment_props( $variation->get_image_id() ), \'image_id\' => $variation->get_image_id(), \'is_downloadable\' => $variation->is_downloadable(), \'is_in_stock\' => $variation->is_in_stock(), \'is_purchasable\' => $variation->is_purchasable(), \'is_sold_individually\' => $variation->is_sold_individually() ? \'yes\' : \'no\', \'is_virtual\' => $variation->is_virtual(), \'max_qty\' => 0 < $variation->get_max_purchase_quantity() ? $variation->get_max_purchase_quantity() : \'\', \'min_qty\' => $variation->get_min_purchase_quantity(), \'price_html\' => $show_variation_price ? \'<span class="price">\' . $variation->get_price_html() . \'</span>\' : \'\', \'sku\' => $variation->get_sku(), \'variation_description\' => wc_format_content( $variation->get_description() ), \'variation_id\' => $variation->get_id(), \'variation_is_active\' => $variation->variation_is_active(), \'variation_is_visible\' => $variation->variation_is_visible(), \'weight\' => $variation->get_weight(), \'weight_html\' => wc_format_weight( $variation->get_weight() ), ), $this, $variation );

add_filter( \'woocommerce_available_variation\', \'add_variation_data\', 10, 3 ); function add_variation_data( $array, $instance, $variation ){ $array[\'custom_data_key\'] = get_post_meta( $array[\'variation_id\'], \'_meta_key\', true ); return $array; }

如何在函数中添加自定义的JavaScript？

我想写一些JavaScript，并想将其分配给一个自定义功能，我探索了很多，但不幸的是，它们都不起作用，任何帮助都将受到欢迎。我的代码如下：add_action(\'init\', function() { if (current_user_can(\'disable_image\')) { //add javascript here } });
