在購物車中使用ajax更新購物車計數時避免產品類型

Question

我正在使用腳本更新Shopify商店中使用Ajax的購物車計數。這工作正常，但我有一個特殊的產品類型，我不希望包括在計數中。我已經設法使用下面的代碼（可以從論壇帖子中找到）來實現常規頁面刷新，但無法理解如何編輯Ajax腳本，以便使用Ajax更新計數，但避免使用產品類型mw_product_option。

任何人都可以幫助我嗎？在此先感謝，我會很感激。

<a href="/cart" id="cartCount"> 
{% assign num = 0 %}  
{% for item in cart.items %}    
{% if item.product.type != "mw_product_option" %}  
    {% capture temp %}{{ num | plus: item.quantity }}{% endcapture %} 
{% endif %} 
{% assign num = temp %} 
{% endfor %} 
<span class="CartCount-alt">{{ num }}</span> 

阿賈克斯劇本我想更新，以避免計入 'mw_product_option'：在全

// Update cart count and show cart link. 
    $.getJSON(_config.shopifyAjaxCartURL, function(cart) { 
    if (_config.cartCountSelector && $(_config.cartCountSelector).size()) { 
    var value = $(_config.cartCountSelector).html() || '0'; 
    $(_config.cartCountSelector).html(value.replace(/[0-9]+/,cart.item_count)).removeClass('hidden-count'); 
    }

OK ，因爲我可以看到everythi你需要的是將服務器腳本轉換爲js格式。它會是這樣的：

$.getJSON(_config.shopifyAjaxCartURL, function(cart) { 
    if (_config.cartCountSelector && $(_config.cartCountSelector).size()) { 
     var value = $(_config.cartCountSelector).html() || '0', 
      itemsCount = 0; 
     $.each(cart.items, function(key, item) { 
      if (item.product_type != "mw_product_option") {  
       itemsCount += item.quantity; 
      } 
     }); 
     $(_config.cartCountSelector).html(value.replace(/[0-9]+/, itemsCount)).removeClass('hidden-count'); 
    }   
    ... 
});
