通过 Product.OptionsPrice 可追踪到 调用 JS 函数的PHTM

if (selectOption.selected) {
curConfig = configOptions[selectOption.value];
} else {
curConfig = {price: 0};
}
optionsPrice.addCustomPrices(optionId + '-' + selectOption.value, curConfig);
optionsPrice.reload();
}
});
} else {
optionsPrice.addCustomPrices(element.id || optionId, curConfig);
optionsPrice.reload();
}
通过 搜索 addCustomPrices optionsPrice.reload() 追踪到调用的JS 库
