这是按钮的代码：

    {% assign p_annual = all_products[section.settings.paid_product_annual] %}
    {% assign p_free = all_products[section.settings.free_product] %}

        {% if section.settings.productlink1label != blank %}
            <button class="btn"
                 type="submit" 
                 name="paid-plan" 
                 id="paid-plan-option-annual" 
                 data-variant-id="{{ p_annual.selected_or_first_available_variant.metafields.subscriptions.discount_variant_id }}" 
                 data-variant-interval-value="{{ p_annual.metafields.subscriptions.shipping_interval_frequency }}" 
                 data-variant-interval-unit="{{ p_annual.metafields.subscriptions.shipping_interval_unit_type }}"
                 data-quickadd-id="{{ p_annual.selected_or_first_available_variant.id }}"
                 data-quickadd-properties
             >
                        {{ p_annual.selected_or_first_available_variant.price | money_without_trailing_zeros }}{{ section.settings.productlink1label }}
             </button>
        {% endif %}

该代码通过 ID 获取项目并发出 AJAX 请求。

// quick add
    _document.on('click', '[data-quickadd-id]', function() {
        let _this = $(this);

        loadingBarTrigger('start');

        itemAdd(
            _this.attr('data-quickadd-id'), 
            _this.attr('data-quickadd-properties'), 
            (_this.attr('data-quickadd-quantity'))
                ? _this.attr('data-quickadd-quantity')
                : 1, 
            (!html.is('#cart')) ? true : false,
            (html.is('#cart')) …
