Какой скрипт (jQuery) добавляет товар в корзину?

   <xsl:template match="/shop">
      <div id="little_cart">
         <div class="cart-block-in">
            <div class="phone">тел. номер</div>
         <div class="email"><a href="">email</a> </div>
            <div class="title">Заказ online</div>
            
            <div class="info">
               
               
               <xsl:variable name="totalQuantity" select="sum(shop_cart[postpone = 0]/quantity)" />
               <xsl:variable name="totalDiscount" select="sum(shop_cart[postpone = 0]/shop_item/property_value[tag_name = 'discount10']/../../quantity)" />
               
               <!-- Вывод общих количества, веса и стоимости товаров -->
         <p>В корзине <b><xsl:value-of select="$totalQuantity"/></b><xsl:text> </xsl:text><xsl:call-template name="declension"><xsl:with-param name="number" select="$totalQuantity"/></xsl:call-template>
                  <br />на сумму <b>
                     
                     <xsl:value-of select="format-number(total_amount, '### ##0', 'my')"/>
                     
               <xsl:text> </xsl:text><xsl:value-of disable-output-escaping="yes" select="shop_currency/name"/></b></p>
               
               
               
            </div>
            
         <a href="{/shop/url}cart/" class="btn-green">Оформить заказ <i class="icon-more"></i></a>
